Phonegap facebook plugin build problems

Hi, wonder if anyone here can help me on this. I am trying to use the phonegap facebook plugin ( but it crashes during the android build process with the following error:

warning: java/net/URI.class(java/net:URI.class): major version 51 is newer than 50, the highest major version supported by this compiler.
   It is recommended that the compiler be upgraded.
   /Users/name/dev/myApp/app/.meteor/local/cordova-build/platforms/android/src/com/adobe/phonegap/push/ cannot find symbol
   symbol  : method setColor(int)
   location: class

It seem to be related to but the solutions in that thread didn’t fix it for me.

Has anyone encounter this error before and have a fix?
