I am sure m2eclipse Maven plugin for Eclipse - the other way around - can do that. You can configure it to download both the source files and javadoc automatically for you.
This is achieved by going into <code>Window &gt; Preferences &gt; Maven and checking the &quot;Download Artifact Sources&quot; and &quot;Download Artifact JavaDoc&quot;</code> options.

Checking download source/javadoc in Eclipse-Maven preference, sometimes is not enough. In the event maven failed to download them for some reason (a network blackout?), maven creates some *.lastUpdated files, then will never download again. My empirical solution was to delete the artifact directory from .m2/repository, and restart the eclipse workspace with download source/javadoc checked and update projects at startup checked as well.
After the workspace has been restarted, maybe some projects can be marked in error, while eclipse progress is downloading, then any error will be cleared.
Maybe this procedure is not so "scientific", but for me did succeded.

I had a similar problem, and the solution that worked best for me was to include the source in the same jar as the compiled code (so a given directory in the jar would include both <code>Foo.java</code> and <code>Foo.class</code>). Eclipse automatically associates the source with the compiled code, and automatically provides the JavaDoc from the source. Obviously, that's only helpful if you control the artifact.
