Package: libtycho-java

Severity: important

I'm trying to build equinox-bundles with the tycho-maven-plugin and I get this exception:

Running Maven in debug mode provides more infortmation:

  [WARNING] The POM for org.eclipse.tycho:tycho-core:jar:0.25.0 is invalid, transitive dependencies (if any) will not be available: 1 problem was encountered while building the effective model for org.eclipse.tycho:tycho-core:0.25.0
  [ERROR] 'dependencies.dependency.version' for org.mockito:mockito-core:jar is missing. @

It seems the lack of version in the pom of tycho-core for the dependency
on mockito-core breaks the dependency resolution. After adding the version
manually the error goes away.
