Overview

Maven Exec plugin lets you run the main method for a Java class in your project, with the project dependencies Automaticall Y included in the classpath. This is article show for you 3 ways of using the MAVEN exec plugin to run Java with code examples. 1) Running from Command line

Since you are is not running your code in a MAVEN phase, the code of the You-need to compile. Remember Exec:java does not automatically compile code your MVN Compile

Once your code is compiled, the following command runs your class without arguments: view plain Copy to Clipboard print? MVN exec:java-dexec.mainclass= "Com.vineetmanohar.module.Main" with arguments: view plain Copy to CLI Pboard print? MVN exec:java-dexec.mainclass= "Com.vineetmanohar.module.Main"-dexec.args= "arg0 arg1 arg2" with runtime Depen Dencies in the CLASSPATH: View plain copy to clipboard print? MVN exec:java-dexec.mainclass= "Com.vineetmanohar.module.Main"-dexec.classpathscope=runtime 2) Running in a phase In Pom.xml

You can also run the main method in a Maven phase. For example, your can run the Codegenerator.main () method As part of Thetest phase. View plain Copy to clipboard print? <build>    <plugins>     <plugin>       <groupId>org.codehaus.mojo</groupId>      <artifactId> exec-maven-plugin</artifactid>      <version>1.1.1</version>       <executions>       <execution>        <phase>test</phase>        < goals>         <goal>java</goal>         </goals>        <configuration>         <mainClass>com.vineetmanohar.module.CodeGenerator</mainClass>          <arguments>          <argument>arg0</argument>          <argument>arg1</argument>          </arguments>        </configuration>        </execution>      </executions>     </plugin>    </plugins>   </build>  

To run the Exec plugin with above configuration, simply run the corresponding phase. MVN Test 3) Running in a profiles in Pom.xml

Can also run the main method in a different profile. Simply wrap the above config in the <profile> tag. View plain Copy to clipboard print? <profiles> <profile> <id>code-generator</id> <build> <plugins> & Lt;plugin> <groupId>org.codehaus.mojo</groupId> <artifactid>exec-maven-plugin</artif Actid> <version>1.1.1</version> <executions> <
