Usage

Simply add the plugin to the build section of your top-level POM as following.


  <build>
    <plugins>
      ...
      <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>flatten-maven-plugin</artifactId>
        <!--<version>1.7.0</version>-->
        <configuration>
        </configuration>
        <executions>
          <!-- enable flattening -->
          <execution>
            <id>flatten</id>
            <phase>process-resources</phase>
            <goals>
              <goal>flatten</goal>
            </goals>
          </execution>
          <!-- ensure proper cleanup -->
          <execution>
            <id>flatten.clean</id>
            <goals>
              <goal>clean</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>

Keep developer information

If you want to keep additional development information in your POM you can configure predefined modes via the flattenMode parameter. For typical open-source-projects you can choose "oss". To keep all additional POM elements and flatten only to a bare minimum use "minimum". Here is an example configuration:


        <configuration>
          <flattenMode>minimum</flattenMode>
        </configuration>
