How to create an archive of archives of project sources with maven

I include the following snippet in the project object model

<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-source-plugin</artifactId> <version>2.1.2</version> </plugin>

according to maven.apache.org the plugin joins the can target to the package phase. However, running "mvn clean; mvn package" does not create the project-sources.jar file in the destination directory.

EDIT: Appropriate, I do not understand the comment from the website I quoted: "[Source: target jar] Becomes the default lifecycle phase: package." I expected that when I turn on the plugin section as shown above, maven already binds the original target: jar to the package phase. Am I mistaken here? What does a comment mean?

The documentation is a bit misleading. The plugin has a default execution phase for the package, but there is no default target. I believe that you specified a goal for the plugin to work.

You need to bind the plugin to the maven lifecycle goal so that it can generate the source jar. Otherwise, you need to explicitly call it mvn source:jar .

As described here , you can bind it to a jar target.

Try the following:

 <project> ... <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-source-plugin</artifactId> <version>2.1.2</version> <executions> <execution> <id>attach-sources</id> <goals> <goal>jar-no-fork</goal> </goals> </execution> </executions> </plugin> </plugins> </build> ... </project>

In this case, the default jar-no-fork default binding to the package life cycle phase is used and probably what you need here.
