> I have noticed this when I was working on the issue:
> http://jira.codehaus.org/browse/MECLIPSE-601
> It looks like that if you have multiple versions of the same plugin, only one 
> of them can be installed as the plugins and models maps are used with the 
> groupId.artifactId as the key.
> So a subsequent version of the same plugin will replace the previous one 
> leading to the last-one-wins situation.
> This might look an innocent bug however image you have two set of plugins in 
> your installation. Then you will end up a randomly -picked list of a single 
> entry list of the plugins in your repository that can possibly lead to 
> unwanted version chaos. Furthermore this situation can be missed easily and 
> can cause a big headache to the experiencing person.
> Attached path resolves the issue...
