@ -45,7 +45,7 @@ In TDengine, the data types below can be used when specifying a column or tag.
:::note
- Only ASCII visible characters are suggested to be used in a column or tag of BINARY type. Multi-byte characters must be stored in NCHAR type.
- The length of BINARY can be up to 16,374 bytes. The string value must be quoted with single quotes. You must specify a length in bytes for a BINARY value, for example binary(20) for up to twenty single-byte characters. If the data exceeds the specified length, an error will occur. The literal single quote inside the string must be preceded with back slash like `\'`
- The length of BINARY can be up to 16,374(data column is 65,517 and tag column is 16,382 since version 3.0.5.0) bytes. The string value must be quoted with single quotes. You must specify a length in bytes for a BINARY value, for example binary(20) for up to twenty single-byte characters. If the data exceeds the specified length, an error will occur. The literal single quote inside the string must be preceded with back slash like `\'`
- Numeric values in SQL statements will be determined as integer or float type according to whether there is decimal point or whether scientific notation is used, so attention must be paid to avoid overflow. For example, 9999999999999999999 will be considered as overflow because it exceeds the upper limit of long integer, but 9999999999999999999.0 will be considered as a legal float number.

- `INTERP` is used to get the value that matches the specified time slice from a column. If no such value exists an interpolation value will be returned based on `FILL` parameter.
- The input data of `INTERP` is the value of the specified column and a `where` clause can be used to filter the original data. If no `where` condition is specified then all original data is the input.
- `INTERP` must be used along with `RANGE`, `EVERY`, `FILL` keywords.
- The output time range of `INTERP` is specified by `RANGE(timestamp1,timestamp2)` parameter, with timestamp1 <= timestamp2. timestamp1 is the starting point of the output time range and must be specified. timestamp2 is the ending point of the output time range and must be specified.
- The output time range of `INTERP` is specified by `RANGE(timestamp1,timestamp2)` parameter, with timestamp1 <= timestamp2. timestamp1 is the starting point of the output time range. timestamp2 is the ending point of the output time range.
- The number of rows in the result set of `INTERP` is determined by the parameter `EVERY(time_unit)`. Starting from timestamp1, one interpolation is performed for every time interval specified `time_unit` parameter. The parameter `time_unit` must be an integer, with no quotes, with a time unit of: a(millisecond)), s(second), m(minute), h(hour), d(day), or w(week). For example, `EVERY(500a)` will interpolate every 500 milliseconds.
- Interpolation is performed based on `FILL` parameter. For more information about FILL clause, see [FILL Clause](../distinguished/#fill-clause).
- When only one timestamp value is specified in `RANGE` clause, `INTERP` is used to generate interpolation at this point in time. In this case, `EVERY` clause can be omitted. For example, SELECT INTERP(col) FROM tb RANGE('2023-01-01 00:00:00') FILL(linear).
- `INTERP` can be applied to supertable by interpolating primary key sorted data of all its childtables. It can also be used with `partition by tbname` when applied to supertable to generate interpolation on each single timeline.
- Pseudocolumn `_irowts` can be used along with `INTERP` to return the timestamps associated with interpolation points(support after version 3.0.2.0).
- Pseudocolumn `_isfilled` can be used along with `INTERP` to indicate whether the results are original records or data points generated by interpolation algorithm(support after version 3.0.3.0).

### Subscription
Connector support data subscription. For more information about subscroption, please refer to [Data Subscription](../../../develop/tmq/).
<Tabs defaultValue="native">
<TabItem value="native" label="native connection">
The `consumer` in the connector contains the subscription api.
#### Create Consumer
The syntax for creating a consumer is `consumer = Consumer(configs)`. For more subscription api parameters, please refer to [Data Subscription](../../../develop/tmq/).
```python
from taos.tmq import Consumer
consumer = Consumer({"group.id": "local", "td.connect.ip": "127.0.0.1"})
```
#### Subscribe topics
The `subscribe` function is used to subscribe to a list of topics.
```python
consumer.subscribe(['topic1', 'topic2'])
```
#### Consume
The `poll` function is used to consume data in tmq. The parameter of the `poll` function is a value of type float representing the timeout in seconds. It returns a `Message` before timing out, or `None` on timing out. You have to handle error messages in response data.
```python
while True:
res = consumer.poll(1)
if not res:
continue
err = res.error()
if err is not None:
raise err
val = res.value()
for block in val:
print(block.fetchall())
```
#### assignment
The `assignment` function is used to get the assignment of the topic.
```python
assignments = consumer.assignment()
```
#### Seek
The `seek` function is used to reset the assignment of the topic.
```python
tp = TopicPartition(topic='topic1', partition=0, offset=0)
consumer.seek(tp)
```
#### After consuming data
You should unsubscribe to the topics and close the consumer after consuming.
```python
consumer.unsubscribe()
consumer.close()
```
#### Tmq subscription example
```python
{{#include docs/examples/python/tmq_example.py}}
```
#### assignment and seek example

```
</TabItem>
<TabItem value="websocket" label="WebSocket connection">
In addition to native connections, the connector also supports subscriptions via websockets.
#### Create Consumer
The syntax for creating a consumer is "consumer = consumer = Consumer(conf=configs)". You need to specify that the `td.connect.websocket.scheme` parameter is set to "ws" in the configuration. For more subscription api parameters, please refer to [Data Subscription](../../../develop/tmq/#create-a-consumer).
```python
import taosws
consumer = taosws.(conf={"group.id": "local", "td.connect.websocket.scheme": "ws"})
```
#### subscribe topics
The `subscribe` function is used to subscribe to a list of topics.
```python
consumer.subscribe(['topic1', 'topic2'])
```
#### Consume
The `poll` function is used to consume data in tmq. The parameter of the `poll` function is a value of type float representing the timeout in seconds. It returns a `Message` before timing out, or `None` on timing out. You have to handle error messages in response data.
```python
while True:
res = consumer.poll(timeout=1.0)
if not res:
continue
err = res.error()
if err is not None:
raise err
for block in message:
for row in block:
print(row)
```
#### assignment
The `assignment` function is used to get the assignment of the topic.
```python
assignments = consumer.assignment()
```
#### Seek
The `seek` function is used to reset the assignment of the topic.
```python
consumer.seek(topic='topic1', partition=0, offset=0)
```
#### After consuming data
You should unsubscribe to the topics and close the consumer after consuming.
```python
consumer.unsubscribe()
consumer.close()
```
#### Subscription example
```python
{{#include docs/examples/python/tmq_websocket_example.py}}

## Install Confluent
Confluent provides two installation methods: Docker and binary packages. This article only introduces binary package installation.
## Install Kafka
Execute in any directory:
````
curl -O http://packages.confluent.io/archive/7.1/confluent-7.1.1.tar.gz
tar xzf confluent-7.1.1.tar.gz -C /opt/
````
```shell
curl -O https://downloads.apache.org/kafka/3.4.0/kafka_2.13-3.4.0.tgz
tar xzf kafka_2.13-3.4.0.tgz -C /opt/
ln -s /opt/kafka_2.13-3.4.0 /opt/kafka
```
Then you need to add the `$CONFLUENT_HOME/bin` directory to the PATH.
Then you need to add the `$KAFKA_HOME/bin` directory to the PATH.
```title=".profile"
export CONFLUENT_HOME=/opt/confluent-7.1.1
export PATH=$CONFLUENT_HOME/bin:$PATH
export KAFKA_HOME=/opt/kafka
export PATH=$PATH:$KAFKA_HOME/bin
```
Users can append the above script to the current user's profile file (~/.profile or ~/.bash_profile)
After the installation is complete, you can enter `confluent version` for simple verification:
```
# confluent version
confluent - Confluent CLI
Version: v2.6.1
Git Ref: 6d920590
Build Date: 2022-02-18T06:14:21Z
Go Version: go1.17.6 (linux/amd64)
Development: false
```
## Install TDengine Connector plugin
### Install from source code
```
```shell
git clone --branch 3.0 https://github.com/taosdata/kafka-connect-tdengine.git
cd kafka-connect-tdengine
mvn clean package
unzip -d $CONFLUENT_HOME/share/java/ target/components/packages/taosdata-kafka-connect-tdengine-*.zip
mvn clean package -Dmaven.test.skip=true
unzip -d $KAFKA_HOME/components/ target/components/packages/taosdata-kafka-connect-tdengine-*.zip
```
The above script first clones the project source code and then compiles and packages it with Maven. After the package is complete, the zip package of the plugin is generated in the `target/components/packages/` directory. Unzip this zip package to plugin path. We used `$CONFLUENT_HOME/share/java/` above because it's a build in plugin path.

We used `$KAFKA_HOME/components/` above because it's a build in plugin path.
### Install with confluent-hub
### Add configuration file
[Confluent Hub](https://www.confluent.io/hub) provides a service to download Kafka Connect plugins. After TDengine Kafka Connector is published to Confluent Hub, it can be installed using the command tool `confluent-hub`.
**TDengine Kafka Connector is currently not officially released and cannot be installed in this way**.
add kafka-connect-tdengine plugin path to `plugin.path` in `$KAFKA_HOME/config/connect-distributed.properties`.
## Start Confluent
```
confluent local services start
```properties
plugin.path=/usr/share/java,/opt/kafka/components
```
:::note
Be sure to install the plugin before starting Confluent. Otherwise, Kafka Connect will fail to discover the plugins.
:::
## Start Kafka Services
:::tip
If a component fails to start, try clearing the data and restarting. The data directory will be printed to the console at startup, e.g.:
Use command bellow to start all services:
```title="Console output log" {1}
Using CONFLUENT_CURRENT: /tmp/confluent.106668
Starting ZooKeeper
ZooKeeper is [UP]
Starting Kafka
Kafka is [UP]
Starting Schema Registry

```
```shell
zookeeper-server-start.sh -daemon $KAFKA_HOME/config/zookeeper.properties
To clear data, execute `rm -rf /tmp/confluent.106668`.
:::
kafka-server-start.sh -daemon $KAFKA_HOME/config/server.properties
### Check Confluent Services Status
connect-distributed.sh -daemon $KAFKA_HOME/config/connect-distributed.properties
Use command bellow to check the status of all service:
```
confluent local services status
```
The expected output is:
```
Connect is [UP]
Control Center is [UP]
Kafka is [UP]
Kafka REST is [UP]
ksqlDB Server is [UP]
Schema Registry is [UP]
ZooKeeper is [UP]
```
### Check Successfully Loaded Plugin
After Kafka Connect was completely started, you can use bellow command to check if our plugins are installed successfully:
```
confluent local services connect plugin list
```shell
curl http://localhost:8083/connectors
```
The output should contains `TDengineSinkConnector` and `TDengineSourceConnector` as bellow:
The output as bellow:
```txt
[]
```
Available Connect Plugins:
[
{
"class": "com.taosdata.kafka.connect.sink.TDengineSinkConnector",
"type": "sink",
"version": "1.0.0"
},
{
"class": "com.taosdata.kafka.connect.source.TDengineSourceConnector",
"type": "source",
"version": "1.0.0"
},
......
```
If not, please check the log file of Kafka Connect. To view the log file path, please execute:
```
echo `cat /tmp/confluent.current`/connect/connect.stdout
```
It should produce a path like:`/tmp/confluent.104086/connect/connect.stdout`
Besides log file `connect.stdout` there is a file named `connect.properties`. At the end of this file you can see the effective `plugin.path` which is a series of paths joined by comma. If Kafka Connect not found our plugins, it's probably because the installed path is not included in `plugin.path`.

5. `fetch.max.rows`: The maximum number of rows retrieved when retrieving the database, default is 100.
6. `query.interval.ms`: The time range of reading data from TDengine each time, its unit is millisecond. It should be adjusted according to the data flow in rate, the default value is 1000.
7. `topic.per.stable`: If it's set to true, it means one super table in TDengine corresponds to a topic in Kafka, the topic naming rule is `<topic.prefix>-<connection.database>-<stable.name>`; if it's set to false, it means the whole DB corresponds to a topic in Kafka, the topic naming rule is `<topic.prefix>-<connection.database>`.
6. `query.interval.ms`: The time range of reading data from TDengine each time, its unit is millisecond. It should be adjusted according to the data flow in rate, the default value is 0, this means to get all the data to the latest time.
7. `out.format`: Result output format. `line` indicates that the output format is InfluxDB line protocol format, `json` indicates that the output format is json. The default is line.
8. `topic.per.stable`: If it's set to true, it means one super table in TDengine corresponds to a topic in Kafka, the topic naming rule is `<topic.prefix><topic.delimiter><connection.database><topic.delimiter><stable.name>`; if it's set to false, it means the whole DB corresponds to a topic in Kafka, the topic naming rule is `<topic.prefix><topic.delimiter><connection.database>`.
9. `topic.ignore.db`: Whether the topic naming rule contains the database name: true indicates that the rule is `<topic.prefix><topic.delimiter><stable.name>`, false indicates that the rule is `<topic.prefix><topic.delimiter><connection.database><topic.delimiter><stable.name>`, and the default is false. Does not take effect when `topic.per.stable` is set to false.

`Consumer` 提供了 Python 连接器订阅 TMQ 数据的 API。
#### 创建 Consumer
创建 Consumer 语法为 `consumer = Consumer(configs)`，参数定义请参考 [数据订阅文档](../../develop/tmq/#%E5%88%9B%E5%BB%BA%E6%B6%88%E8%B4%B9%E8%80%85-consumer)。
```python
from taos.tmq import Consumer
consumer = Consumer({"group.id": "local", "td.connect.ip": "127.0.0.1"})
```
#### 订阅 topics
Comsumer API 的 `subscribe` 方法用于订阅 topics，consumer 支持同时订阅多个 topic。
```python
consumer.subscribe(['topic1', 'topic2'])
```
#### 消费数据
Consumer API 的 `poll` 方法用于消费数据，`poll` 方法接收一个 float 类型的超时时间，超时时间单位为秒（s），`poll` 方法在超时之前返回一条 Message 类型的数据或超时返回 `None`。消费者必须通过 Message 的 `error()` 方法校验返回数据的 error 信息。
```python
while True:
res = consumer.poll(1)
if not res:
continue
err = res.error()
if err is not None:
raise err
val = res.value()
for block in val:
print(block.fetchall())
```
#### 获取消费进度
Consumer API 的 `assignment` 方法用于获取 Consumer 订阅的所有 topic 的消费进度，返回结果类型为 TopicPartition 列表。
```python
assignments = consumer.assignment()
```
#### 重置消费进度
Consumer API 的 `seek` 方法用于重置 Consumer 的消费进度到指定位置，方法参数类型为 TopicPartition。
```python
tp = TopicPartition(topic='topic1', partition=0, offset=0)
consumer.seek(tp)

- 表的每行长度不能超过 48KB（从 3.0.5.0 版本开始为 64KB）（注意：每个 BINARY/NCHAR 类型的列还会额外占用 2 个字节的存储位置）。
- 虽然 BINARY 类型在底层存储上支持字节型的二进制字符，但不同编程语言对二进制数据的处理方式并不保证一致，因此建议在 BINARY 类型中只存储 ASCII 可见字符，而避免存储不可见字符。多字节的数据，例如中文字符，则需要使用 NCHAR 类型进行保存。如果强行使用 BINARY 类型保存中文字符，虽然有时也能正常读写，但并不带有字符集信息，很容易出现数据乱码甚至数据损坏等情况。
- BINARY 类型理论上最长可以有 16,374 字节。BINARY 仅支持字符串输入，字符串两端需使用单引号引用。使用时须指定大小，如 BINARY(20) 定义了最长为 20 个单字节字符的字符串，每个字符占 1 字节的存储空间，总共固定占用 20 字节的空间，此时如果用户字符串超出 20 字节将会报错。对于字符串内的单引号，可以用转义字符反斜线加单引号来表示，即 `\'`。

- SQL 语句中的数值类型将依据是否存在小数点，或使用科学计数法表示，来判断数值类型是否为整型或者浮点型，因此在使用时要注意相应类型越界的情况。例如，9999999999999999999 会认为超过长整型的上边界而溢出，而 9999999999999999999.0 会被认为是有效的浮点数。

## 什么是 Confluent？
[Confluent](https://www.confluent.io/) 在 Kafka 的基础上增加很多扩展功能。包括：
1. Schema Registry
2. REST 代理
3. 非 Java 客户端
4. 很多打包好的 Kafka Connect 插件
5. 管理和监控 Kafka 的 GUI —— Confluent 控制中心
这些扩展功能有的包含在社区版本的 Confluent 中，有的只有企业版能用。
![TDengine Database Kafka Connector -- Confluent introduction](kafka/confluentPlatform.webp)
Confluent 企业版提供了 `confluent` 命令行工具管理各个组件。
## 前置条件
运行本教程中示例的前提条件。
1. Linux 操作系统
2. 已安装 Java 8 和 Maven
3. 已安装 Git
3. 已安装 Git、curl、vi
4. 已安装并启动 TDengine。如果还没有可参考[安装和卸载](/operation/pkg-install)
## 安装 Confluent
Confluent 提供了 Docker 和二进制包两种安装方式。本文仅介绍二进制包方式安装。
## 安装 Kafka
在任意目录下执行：
```
curl -O http://packages.confluent.io/archive/7.1/confluent-7.1.1.tar.gz
tar xzf confluent-7.1.1.tar.gz -C /opt/
```shell
curl -O https://downloads.apache.org/kafka/3.4.0/kafka_2.13-3.4.0.tgz
tar xzf kafka_2.13-3.4.0.tgz -C /opt/
ln -s /opt/kafka_2.13-3.4.0 /opt/kafka
```
然后需要把 `$CONFLUENT_HOME/bin` 目录加入 PATH。
然后需要把 `$KAFKA_HOME/bin` 目录加入 PATH。
```title=".profile"
export CONFLUENT_HOME=/opt/confluent-7.1.1
export PATH=$CONFLUENT_HOME/bin:$PATH
export KAFKA_HOME=/opt/kafka
export PATH=$PATH:$KAFKA_HOME/bin
```
以上脚本可以追加到当前用户的 profile 文件（~/.profile 或 ~/.bash_profile）
安装完成之后，可以输入`confluent version`做简单验证：
```
# confluent version
confluent - Confluent CLI
Version: v2.6.1
Git Ref: 6d920590
Build Date: 2022-02-18T06:14:21Z
Go Version: go1.17.6 (linux/amd64)
Development: false
```
## 安装 TDengine Connector 插件
### 从源码安装
### 编译插件
```
```shell
git clone --branch 3.0 https://github.com/taosdata/kafka-connect-tdengine.git
cd kafka-connect-tdengine
mvn clean package
unzip -d $CONFLUENT_HOME/share/java/ target/components/packages/taosdata-kafka-connect-tdengine-*.zip
mvn clean package -Dmaven.test.skip=true
unzip -d $KAFKA_HOME/components/ target/components/packages/taosdata-kafka-connect-tdengine-*.zip
```
以上脚本先 clone 项目源码，然后用 Maven 编译打包。打包完成后在 `target/components/packages/` 目录生成了插件的 zip 包。把这个 zip 包解压到安装插件的路径即可。上面的示例中使用了内置的插件安装路径： `$CONFLUENT_HOME/share/java/`。

### 用 confluent-hub 安装
### 配置插件
[Confluent Hub](https://www.confluent.io/hub) 提供下载 Kafka Connect 插件的服务。在 TDengine Kafka Connector 发布到 Confluent Hub 后可以使用命令工具 `confluent-hub` 安装。
**TDengine Kafka Connector 目前没有正式发布，不能用这种方式安装**。
将 kafka-connect-tdengine 插件加入 `$KAFKA_HOME/config/connect-distributed.properties` 配置文件 plugin.path 中
## 启动 Confluent
```
confluent local services start
```properties
plugin.path=/usr/share/java,/opt/kafka/components
```

### 验证各个组件是否启动成功
### 验证 kafka Connect 是否启动成功
输入命令：
```
confluent local services status
```shell
curl http://localhost:8083/connectors
```
如果各组件都启动成功，会得到如下输出：
```txt
[]
```
Connect is [UP]
Control Center is [UP]
Kafka is [UP]
Kafka REST is [UP]
ksqlDB Server is [UP]
Schema Registry is [UP]
ZooKeeper is [UP]
```
### 验证插件是否安装成功
在 Kafka Connect 组件完全启动后，可用以下命令列出成功加载的插件：
```
confluent local services connect plugin list
```
如果成功安装，会输出如下：
```txt {4,9}
Available Connect Plugins:
[
{
"class": "com.taosdata.kafka.connect.sink.TDengineSinkConnector",
"type": "sink",
"version": "1.0.0"
},
{
"class": "com.taosdata.kafka.connect.source.TDengineSourceConnector",
"type": "source",
"version": "1.0.0"
},
......
```
如果插件安装失败，请检查 Kafka Connect 的启动日志是否有异常信息，用以下命令输出日志路径：
```
echo `cat /tmp/confluent.current`/connect/connect.stdout
```
该命令的输出类似： `/tmp/confluent.104086/connect/connect.stdout`。
与日志文件 `connect.stdout` 同一目录，还有一个文件名为： `connect.properties`。在这个文件的末尾，可以看到最终生效的 `plugin.path`， 它是一系列用逗号分割的路径。如果插件安装失败，很可能是因为实际的安装路径不包含在 `plugin.path` 中。

3. `timestamp.initial`: 数据同步起始时间。格式为'yyyy-MM-dd HH:mm:ss'，若未指定则从指定 DB 中最早的一条记录开始。
4. `poll.interval.ms`: 检查是否有新建或删除的表的时间间隔，单位为 ms。默认为 1000。
5. `fetch.max.rows` : 检索数据库时最大检索条数。 默认为 100。
6. `query.interval.ms`: 从 TDengine 一次读取数据的时间跨度，需要根据表中的数据特征合理配置，避免一次查询的数据量过大或过小；在具体的环境中建议通过测试设置一个较优值，默认值为 1000.
7. `topic.per.stable`: 如果设置为true，表示一个超级表对应一个 Kafka topic，topic的命名规则 `<topic.prefix>-<connection.database>-<stable.name>`；如果设置为 false，则指定的 DB 中的所有数据进入一个 Kafka topic，topic 的命名规则为 `<topic.prefix>-<connection.database>`
6. `query.interval.ms`: 从 TDengine 一次读取数据的时间跨度，需要根据表中的数据特征合理配置，避免一次查询的数据量过大或过小；在具体的环境中建议通过测试设置一个较优值，默认值为 0，即获取到当前最新时间的所有数据。
7. `out.format` : 结果集输出格式。`line` 表示输出格式为 InfluxDB Line 协议格式，`json` 表示输出格式是 json。默认为 line。
8. `topic.per.stable`: 如果设置为 true，表示一个超级表对应一个 Kafka topic，topic的命名规则 `<topic.prefix><topic.delimiter><connection.database><topic.delimiter><stable.name>`；如果设置为 false，则指定的 DB 中的所有数据进入一个 Kafka topic，topic 的命名规则为 `<topic.prefix><topic.delimiter><connection.database>`
9. `topic.ignore.db`: topic 命名规则是否包含 database 名称，true 表示规则为 `<topic.prefix><topic.delimiter><stable.name>`，false 表示规则为 `<topic.prefix><topic.delimiter><connection.database><topic.delimiter><stable.name>`，默认 false。此配置项在 `topic.per.stable` 设置为 false 时不生效。
10. `topic.delimiter`: topic 名称分割符，默认为 `-`。

# How to Run the Consumer Demo Code On Linux OS
TDengine's Consumer demo project is organized in a Maven way so that users can easily compile, package and run the project. If you don't have Maven on your server, you may install it using
```
sudo apt-get install maven
```
## Install TDengine Client and TaosAdapter
Make sure you have already installed a tdengine client on your current develop environment.
Download the tdengine package on our website: ``https://www.taosdata.com/cn/all-downloads/`` and install the client.
## Run Consumer Demo using mvn plugin
run command:
```
mvn clean compile exec:java -Dexec.mainClass="com.taosdata.ConsumerDemo"
```
## Custom configuration
```shell
# the host of TDengine server
export TAOS_HOST="127.0.0.1"
# the port of TDengine server
export TAOS_PORT="6041"
# the consumer type, can be "ws" or "jni"
export TAOS_TYPE="ws"
# the number of consumers
export TAOS_JDBC_CONSUMER_NUM="1"
# the number of processors to consume
export TAOS_JDBC_PROCESSOR_NUM="2"
# the number of records to be consumed per processor per second
export TAOS_JDBC_RATE_PER_PROCESSOR="1000"
# poll wait time in ms
export TAOS_JDBC_POLL_SLEEP="100"
```
## Run Consumer Demo using jar
To compile the demo project, go to the source directory ``TDengine/tests/examples/JDBC/consumer-demo`` and execute
```
mvn clean package assembly:single
```
To run ConsumerDemo.jar, go to ``TDengine/tests/examples/JDBC/consumer-demo`` and execute
```
java -jar target/ConsumerDemo-jar-with-dependencies.jar
```
