<pre>sudo apt-get install maven</pre>
```
sudo apt-get install maven
```

## Run jdbcDemo using mvn plugin
run command:
<pre> mvn clean compile exec:java -Dexec.mainClass="com.taosdata.example.JdbcDemo"</pre>
```
mvn clean compile exec:java -Dexec.mainClass="com.taosdata.example.JdbcDemo"
```
and run with your customed args
<pre>mvn clean compile exec:java -Dexec.mainClass="com.taosdata.example.JdbcDemo" -Dexec.args="-host [HOSTNAME]"</pre>
```
mvn clean compile exec:java -Dexec.mainClass="com.taosdata.example.JdbcDemo" -Dexec.args="-host [HOSTNAME]"
```
## Compile the Demo Code and Run It
To compile the demo project, go to the source directory ``TDengine/tests/examples/JDBC/JDBCDemo`` and execute
```
cd TDengine/src/connector/jdbc
mvn clean package -Dmaven.test.skip=true
cp target/taos-jdbcdriver-2.0.x-dist.jar ../../../tests/examples/JDBC/JDBCDemo/target/
cd ../../../tests/examples/JDBC/JDBCDemo
<pre>
mvn clean package assembly:single
</pre>
```
The ``pom.xml`` is configured to package all the dependencies into one executable jar file.
To run it, go to ``TDengine/tests/examples/JDBC/JDBCDemo/target`` and execute
```
java -Djava.ext.dirs=.:$JAVA_HOME/jre/lib/ext -jar JDBCDemo-SNAPSHOT-jar-with-dependencies.jar -host localhost
```
To run it, go to ``examples/JDBC/JDBCDemo/target`` and execute
<pre>java -jar JDBCDemo-SNAPSHOT-jar-with-dependencies.jar -host localhost</pre>
