Antoine Pitrou commented on ARROW-9470: --------------------------------------- It looks like the Apache RAT Maven plugin isn't compatible with multi-thread builds. Is it important to enable RAT checks in the Java build system? We already have a custom CI run, as well as {{archery lint --rat}} to check for RAT issues. cc [~lidavidm] [~emkornfield] [~rymurr] > [CI][Java] Run Maven in parallel > -------------------------------- > > Key: ARROW-9470 > URL: https://issues.apache.org/jira/browse/ARROW-9470 > Project: Apache Arrow > Issue Type: Improvement > Components: Continuous Integration, Developer Tools, Java > Reporter: Antoine Pitrou > Priority: Minor > > It looks like Maven nowadays supports multi-threaded builds, but we're not > using them: > https://cwiki.apache.org/confluence/display/MAVEN/Parallel+builds+in+Maven+3 -- This message was sent by Atlassian Jira (v8.3.4#803005)
