proguard issue with 2.0

[wookietreiber]

Adding macroid 2.0 to a fresh project created with sbt-android 1.7.10 gen-android yields the following proguard issues. How does one fix them? Shouldn't there be somewhere a list with proguard options that need to be enabled for macroid to work?

Note: there were 1 classes trying to access enclosing classes using reflection.
      You should consider keeping the inner classes attributes
      (using '-keepattributes InnerClasses').
      (http://proguard.sourceforge.net/manual/troubleshooting.html#attributes)
Note: there were 3 unresolved dynamic references to classes or interfaces.
      You should check if you need to specify additional program jars.
      (http://proguard.sourceforge.net/manual/troubleshooting.html#dynamicalclass)
Note: there were 1 accesses to class members by means of introspection.
      You should consider explicitly keeping the mentioned class members
      (using '-keep' or '-keepclassmembers').
      (http://proguard.sourceforge.net/manual/troubleshooting.html#dynamicalclassmember)
Warning: there were 2 unresolved references to program class members.
         Your input classes appear to be inconsistent.
         You may need to recompile the code.
