Ben Tatham commented on MSOURCES-44:
------------------------------------
We have the same issue, with some test-less projects (like parent pom projects,
that are themselves a child pom of our overall company pom that says to create
source and test-source jars for all projects, using no-fork goals).
> If project doesn't contain sources (contains only test sources) source:jar
> will fail

> Key: MSOURCES-44
> URL: http://jira.codehaus.org/browse/MSOURCES-44
> Project: Maven 2.x Source Plugin
> Issue Type: Bug
> Affects Versions: 2.1
> Environment: WinXp SP3, Cygwin
> Reporter: Bugittaa Pahasti
>
> We are running all of our CI builds with the release profile so that javadocs
> and sources are generated. However, one module in a multi-module build
> contains only test sources. After updating from 2.0.4 to 2.1 the build will
> fail. The same error occurs when source:jar is run manually. Below is the
> stack trace from jar:source. It might be intentional that the build will fail
> in case source:jar is run from command line, but when using release profile
> the failure is quite problematic.
