Tibor Digana commented on SUREFIRE-1837:
----------------------------------------
[~gnodet]
The server would run witin the MVN process?
I don't mean mvnd, do you?
I am asking because this because you said that the server will for few minutes
longer but the mvn process is expected to exit after the job is done. Is it
another process?
Notice: Perhaps the incremental build from De.Ba. should have the cache on the
same server. WDYT?
