Alexander Ashitkin updated MNG-5750:
------------------------------------
Description:
We have a large project of 300+ modules which regularly fails with different
kind of errors in different places. The issue is reliably reproduced with
parallel build and is not happens in single threaded. The optimal concurrency
level for our project ~10 threads. At this level ~%20 of builds fail. To
workaround the issue we reduced concurrency to 4 in development builds and
reverted production build to 1 thread.
Main point of failures:
# Surefire ClassNotFound. Reported and investigated in SUREFIRE-1132. Points to
a problem with MavenProject#getArtifacts - empty set unexpectedly returned.
# unexpected compilation failures because of incorrect classpath (lterally all
dependencies are not on the classpath), like: {code}

# unexpected NPE in archiver plugins, eg jar, assembly. Reported with stack
traces in MJAR-192
At this point the issue looks like problem with MavenProject#getArtifacts in
concurrent builds.
To help with the issue im happy to implement or evaluate any custom assembly to
trace this down. Unfortunately i cannot submit my project - it is proprietary.
Thanks in advance, Alexander
