Hello.

I get the following error while building a project with the GWT plugin:

What could it be caused by?

You're using "the other plugin"

Try re-running your Maven command with -Dgwt.compiler.strict or -Dgwt.logLevel=TRACE (or DEBUG) as suggested by the error to understand why those 80 files are in error.

You can ask for help in the Google Group or Gitter chatroom
