Kari J. Niemi commented on MNG-4996:
------------------------------------
Uhhh...now this got to the level of my incompetence. Checked out succesfully,
but my internal repository does not contain all the artifacts needed for
building and I'm not supposed(capable? don't know how...) to use external
repositories(maven central)...
(Yes, you figured it, it's unfortunately closed source.)
> Maven3 parallel build fails occasionally for classpath problems.

> In a multimodule (>120 modules) maven build, the compiler plug-in would seem

> And of course the compilation fails because none of the dependencies are
> added to the classpath. Sometimes it goes fine in the multi-module build, but
> every now and then it fails for this.
