>             Project: Maven 2.x Eclipse Plugin
>          Issue Type: Bug
>          Components: PDE support
>    Affects Versions: 2.5.1
>         Environment: Windows XP
> Java 1.4.2
>            Reporter: Phillip Merensky
>         Attachments: MECLIPSE-491.patch

> The attached Patch fixes two Issues:
> #  NPE when executing install-plugins and parsed jar has no manifest:
>  In this case an info log message will be generated and the respective jar will be skipped.
> # If you build your Eclipse distribution with maven from scratch - that is all your plugins
will be resolved and installed by maven into an assembly directory - it is obstructive to
exit the execution of the install-plugins goal when the plugins folder is missing. Thus I
changed the code to only output an info message and to create the missing plugin dir.
> Hope this helps.
> Regards,
> Phillip
