Hudson commented on MNG-6323: ----------------------------- Build succeeded in Jenkins: Maven TLP (wip) » maven » MNG-6362 #11 See https://builds.apache.org/job/maven-wip/job/maven/job/MNG-6362/11/ > Deadlock in multithreaded dependency resolution > ----------------------------------------------- > > Key: MNG-6323 > URL: https://issues.apache.org/jira/browse/MNG-6323 > Project: Maven > Issue Type: Bug > Affects Versions: 3.5.2 > Reporter: Ben Caradoc-Davies > Assignee: Robert Scholte > Priority: Major > Fix For: 3.5.3 > > Attachments: geoserver-community-maven-hang-jstack-2.txt, > geoserver-community-maven-hang-jstack.txt > > > Maven 3.5.2 multithreaded builds experience a deadlock not seen with Maven > 3.5.0. > To reproduce the issue, clone GeoServer: > {noformat} > git clone https://github.com/geoserver/geoserver.git > cd geoserver > {noformat} > Build GeoServer community modules with: > {noformat} > mvn -f src/community/pom.xml -B -T4 -U -Prelease -PcommunityRelease > -DskipTests clean install > {noformat} > Builds that normally take 2-4 minutes instead experience long hangs. > {{jstack}} output (attached) suggests a deadlock (two different hangs > attached). Some of the locks are in {{TIME_WAIT}} and eventually the build > completes after 30-45 minutes, but this is enough to cause builds on Travis > to be killed for their failure to output for ten minutes. (Travis upgraded to > Maven 3.5.2 a week ago.) > I have only seen the failures with -U. The hang does not occur in > single-threaded builds. There are no "*.lock" files in the local repository > during the hang so the deadlocks are not mediated by the filesystem. CPU > utilisation is zero suggesting a deadlock not a livelock. > See also discussion on the geoserver-devel mailing list: > http://osgeo-org.1560.x6.nabble.com/Travis-failures-started-with-new-trusty-images-td5346836.html -- This message was sent by Atlassian JIRA (v7.6.3#76005)
