Michael Osipov commented on MNG-6984: ------------------------------------- Can you futher describe how race conditions affect your build, maybe a log file if possible? > maven concurrent builds ignore synchronized in mojo execute-method > ------------------------------------------------------------------ > > Key: MNG-6984 > URL: https://issues.apache.org/jira/browse/MNG-6984 > Project: Maven > Issue Type: Bug > Affects Versions: 3.6.0, 3.6.3 > Reporter: Thomas Lörcher > Priority: Critical > > I have written a custom maven-Mojo. > Since libraries used in this mojo are not thread-safe, i followed the guide > [https://cwiki.apache.org/confluence/display/MAVEN/Parallel+builds+in+Maven+3] > to avoid parallel executions of the code. > Doesnt seem to work though. > I tried to use other approaches like semaphors or synchronized functions, > maven does execute the code snippets in parallel. It seems to me that every > mvn module will get build in an own process. > Build started using > mvn clean package -T1C -- This message was sent by Atlassian Jira (v8.3.4#803005)
