> 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
