Subject [jira] Commented: (MRELEASE-318) Release plugin throws NullPointerException when using version range for dependency
Date Fri, 22 Oct 2010 04:23:33 GMT

    [ http://jira.codehaus.org/browse/MRELEASE-318?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=240546#action_240546
] 

Phillip Hellewell commented on MRELEASE-318:
--------------------------------------------

I'm getting this in 2.1 using an exact version number, e.g., [1.2.5].  2.0-beta-9 works fine.
 Should I create a new bug or is there a way to re-open this?  Migrating to Maven 3 is not
an option for us at this time.

java.lang.NullPointerException: version was null for ad.3rdparty:boost

> After upgrading to 2.0.8 I find that the release plugin throws NPE if any dependency
uses version range.
> I have one dependency with version range <version>[1.0,2.0)</version> the
rest are test scope with fixed version.

> It seems the reason version is null is that the call to selectVersionFromNewRangeIfAvailable()
assumes that versionRange.getRecommendedVersion() will always return non-null, else it sets
the version to null!  However during the release:prepare phase this is not true, see the output:

> [13:42:04]: [INFO] Verifying that there are no local modifications...

> [13:42:05]: TEST!!! version=null
> [13:42:05]: TEST!!! versionRange=[1.0,2.0)
> [13:42:05]: TEST!!! getRecommendedVersion=null
> TEST!!! Lines are my test code so I could see what is going on here.
