[jira] (MJAR-168) Update to latest plexus-archiver

Osvaldo Doederlein created MJAR-168:
---------------------------------------

             Summary: Update to latest plexus-archiver
                 Key: MJAR-168
                 URL: https://jira.codehaus.org/browse/MJAR-168
             Project: Maven 2.x JAR Plugin
          Issue Type: Improvement
    Affects Versions: 2.4
         Environment: Any Unix system that has some ldap groups
            Reporter: Osvaldo Doederlein


maven-jar-plugin regresses horribly with JDK 7 compared to JDK 6. The cause is well known and already fixed in plexus-io, PLXCOMP-203, but the fixed version of plexus-io has yet to be used by maven-jar-plugin. Here's some benchmark from y project:

Standard build with maven 3.0.x or 3.1-alpha1:

[INFO] Total time: 3:03.048s
[INFO] Finished at: Tue Jul 09 15:22:02 EDT 2013
[INFO] Final Memory: 40M/221M

After rebuilding maven-jar-plugin, changing its POM to use plexus-archiver 2.4.1 (which in turn uses the latest plexus-io):

[INFO] Total time: 41.786s
[INFO] Finished at: Tue Jul 09 15:28:26 EDT 2013
[INFO] Final Memory: 47M/403M

It seems like a trivial fix, all maven-jar unit tests pass.
