Add the effective pom.xml in the META-INF directory

Question

When I build a JAR library using Maven 2 (version 2.0.9 or 2.2.1), the pom.xml of the library is copied in the META-INF/maven/[g

Answer 1

Use https://www.mojohaus.org/flatten-maven-plugin/

It will set updatePomFile true by default.

Its not what you asked for, but its what you want.

Answer 2

You can generate the effective-pom.xml during install cycle

<plugin>
     <groupId>org.apache.maven.plugins</groupId>
     <artifactId>maven-help-plugin</artifactId>
     <version>2.1.1</version>
     <executions>
        <execution>
           <phase>generate-resources</phase>
       <goals>
          <goal>effective-pom</goal>
       </goals>
       <configuration>
          <output>${project.build.outputDirectory}\effective-pom.xml</output>
       </configuration>
      </execution>
  </executions>
</plugin>

But to copy this effective-pom.xml to under META-INF/maven/[groupId]/[artifactId]/ directory of the JAR file, you will have to write a custom Jar mojo (just by extending org.apache.maven.plugin.jar.JarMojo) because the code that copies the pom.xml to META-INF is hard-coded in org.apache.maven.archiver.MavenArchiver (Line 487) (and i think there is no apparent way to set/override this behavior from pom.xml).
