[jira] Closed: (MECLIPSE-150) [with PATCH] Plugin generates invalid Eclipse project files when multiproject contains two references to the same artifact

["Barrie Treloar (JIRA)" <ji...@codehaus.org>]

     [ http://jira.codehaus.org/browse/MECLIPSE-150?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Barrie Treloar closed MECLIPSE-150.
-----------------------------------

       Resolution: Fixed
    Fix Version/s: 2.6

IdeDependency is comparable and equals delegates to compare, hashCode() also defined.

AbstractIdeSupportMojo.doDependencyResolution() maintains a list of dependencies and code already guards against duplicates:

{code:java}
// no duplicate entries allowed. System paths can cause this problem.
if ( !dependencies.contains( dep ) )
{
  dependencies.add( dep );
}
{code}

This should resolve your problem.

> HI
> in same circumstances the eclipse-plugin will generate a Eclipse project file which contains two references to the same artifact/project which will cause Eclipse to fail loading the project. The attached patch is very small and solves this problem by managing the references within a java.util.Set and using equals() within the IdeDependency.java class.
> Thanks
