Usage

Describe Goal

Assuming you have configured the Maven JMod Plugin accordingly to the usage page like the following:

<project>
  [...]
  <build>
    [...]
    <plugins>
      [...]
      <plugin>
        <artifactId>maven-jmod-plugin</artifactId>
        <version>3.0.0-alpha-1</version>
        <extensions>true</extensions>
        <configuration>
          <!-- configuration elements goes here -->
        </configuration>
        <executions>
          <execution>
            <id>describe</id>
            <goals>
              <goal>describe</goal>
            </goals>
            <phase>verify</phase>
          </execution>
        </executions>
      </plugin>        
      </plugin>
   [...]
</project>

You can run via:

mvn clean verify

During the above call of Maven the jmod files will be generated and by the describe goal you will get an output like the following (using toolchains):

[INFO] --- maven-jmod-plugin:3.0.0-alpha-1:describe (describe) @ first-jmod ---
