> Key: MNG-4648
> URL: http://jira.codehaus.org/browse/MNG-4648
> Project: Maven 2 & 3
> Issue Type: Bug
> Components: Plugins and Lifecycle, POM
> Affects Versions: 3.0-beta-1
> Reporter: Ivica Loncar
>
> As a user i would like to see better error reporting from
> DefaultPluginRealmCache#pluginHashCode method
> Currently it calculates hash value based on a dependency metadata, but if I
> omit version it fails with NullPointer exception.
> It would be more user friendly to validate metadata prior to calculating hash
> value and to display more meaningful error to the end user.
> Test scenario:
> - configure plugin and create dependencies
> - add dependency but DO NOT specify version
> - run maven such that plugin is invoked
> maven will fail without reporting which dependency doesn't have version
