Unfortunately I don't know enough Java to fix this. Nor do I have a clue what
the code is
supposed to be doing. However, it seems that
getMavenPluginConfigurationsImpl().get()
returns a single HashMap, and getMavenPluginOptions is trying to cast this to
an array of Maps.
Is this possible?
The previous version, 2.0-beta-1, works OK.
