> maven-jar-plugin is very slow on machines with slow Unix group lookups
> ----------------------------------------------------------------------
>
> Key: MNG-5709
> URL: https://jira.codehaus.org/browse/MNG-5709
> Project: Maven
> Issue Type: Bug
> Affects Versions: 3.1.1, 3.2.3
> Environment: Ubuntu Trusty, OpenJDK 7 (modified)
> Reporter: Brian Slesinsky
>
> While building a Maven project, it appeared to hang while packaging a large
> jar. Running jstack showed that it was getting stuck in the Java 7
> implementation of getgrgid. It looks like it's doing this for every file and
> there are lots of files. This is already fixed in plexus-io-2.0.5 [1] but
> Maven needs to upgrade to the new version.
> A workaround is to patch it in the the pom, such as [2]. However, this needs
> to be done in each project.
> This isn't easy to reproduce; I've seen it on some machines but not others.
