>             Project: Maven Eclipse Plugin
>          Issue Type: Bug
>          Components: Core : Workspace settings
>    Affects Versions: 2.8
>            Reporter: Peter Winckles
>            Priority: Minor

> An NPE is thrown from EclipsePlugin.isAvailableAsAWorkspaceProject() if there are existing projects in the Eclipse workspace that are not properly configured (ie have a pom without a GAV definition).  I would expect the plugin to simply ignore bad projects, particularly when they aren't in the target project's dependency tree.
> To reproduce, simply delete the the group definition from a project, and run maven eclipse:eclipse on an unrelated project in the same workspace.
