Brian Slesinsky created MNG-5709:
------------------------------------
Summary: very slow builds 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: 3.2.3, 3.1.1
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.
