I include the following snippet in a projects 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 attaches the jar goal to the package phase. However doing "mvn clean ; mvn package" does not generate a project-sources.jar in the target directory.
EDIT: Propably i do not understand the comment from the website, which i quoted: "[The source:jar goal] Binds by default to the lifecycle phase: package." I expected that, when i include the plugin section as shown above maven already binds the source:jar goal to the package phase. Am i mistaking here? What does the comment mean?

The source plugin can be used to create a jar file of the project sources from the command line or by binding the goal to the project's build lifecycle. To generate the jar from the command line, use the following command: mvn source:jar.
Execute the “mvn clean install” command to built the project and deploy the jar files to the target folder.
Go to that root and run mvn package. If this is correct, there should be a new folder with the name target in the root of the project. Inside this folder there should be the jar file.
The documentation is a little misleading. The plugin has a default execution phase of package but there is no default goal. I believe that you have specify a goal in order for the plugin to work.
You need to bind the plugin to a maven life-cycle goal for it to generate the source jar. Otherwise, you need to invoke it explicitly mvn source:jar
.
As documented here, you can bind it to the jar
goal.
Try this:
<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>
It uses then the default binding of jar-no-fork
goal to package
phase of the lifecycle and that's probably what you need here.
