Crosswalk build fails with error related to plugin

So the install of Crosswalk worked fine but running an android build fails due to an issue with this plugin - (part error below).

The question is, do plugins need to specifically support Crosswalk? i.e. is the problem one for the developers of this plugin or are there issues that need to be resolved in our app?

Any direction would be helpful.

import com.craftar.CraftARActivity;
etc, etc, etc…

Right now, with crosswalk, we’re pulling in a beta of cordova-android 4.0, so some hiccups are to be expected.
Once cordova releases 4.0 officially, then the plugin should be updated by the author.
