Apparently that's the version that's referenced by a dependency, I had
the same thing happen! You can simply delete that dependency, but it
will come back next time you run MavenTool.
I fixed some bugs in MavenTool that were preventing it from getting all
transitive dependencies - unfortunately, that's "uncovered" some
dependencies that have problems!
You can also add a property to the depdency that causes the mockobjects
jar to be included called <mavenToolSkip>true</mavenToolSkip> This
indicates that the recursion is to stop on that jar - e.g. it does not
check for further dependencies of that jar.
For that property to work, it's best to put the dependency that uses it
near the top of the project.xml (otherwise another dependency might
include the one you want to skip in *its* recursion)
