Same problem here. I'm compiling with Oracle's 1.7.0.u45 JDK. I get a
bunch of warnings like this:
[WARN] Unable to read:
jar:file:/C:/gwt-2.7.0/gwt-user.jar!/com/google/gwt/core/Core.gwtar.
Skipping: java.io.InvalidClassException:
com.google.gwt.dev.jjs.SourceOrigin$1; local class incompatible: stream
classdesc serialVersionUID = -2407201776821563037, local class
serialVersionUID = 4713379764594032837
before my compile terminates with this:
Adding '1' new generated units
Compiling...
Compilation completed in 0.01 seconds
Removing invalidated units
[ERROR] Unexpected internal compiler error
