Subject [jira] Commented: (MNG-4112) Set property containing the currently executing maven version.
Date Wed, 01 Apr 2009 04:26:12 GMT

    [ http://jira.codehaus.org/browse/MNG-4112?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=171658#action_171658
] 

Paul Gier commented on MNG-4112:
--------------------------------

I looked into it a bit, and I should be able to get the version the same way that it's retrieved
when you run "mvn -version" from the command line.  It gets the information from the maven
core jar, so it wouldn't be dependent on the RuntimeInformation.
I wasn't sure if it should be a system property, or should the scope of the property be more
localized?

The RuntimeInformation could be used in a goal in a plugin (maybe the buildnumber plugin?)
to allow the version to be accessed in maven pre 3.0.

> It would be helpful to have an easy way to access the current version of maven.  This
might be accomplished by setting a property like "maven.version" during startup that would
be available to the pom and/or to plugins.  This could be used to record what version of maven
was used during the build to facilitate build reproducibility.
