Re: How to migrate gwt 2.8.1 project to gwt 2.9.0 in eclipse?

Reads like your war file is empty.

You *must* declare your dependencies via Gradle and if you are mixing server and client code, (a really bad idea), together you will need to remove the root spec exclude filters.

Thank You Michael!

It was a big help.

Except the :farmRun I can successfully execute the commands.

:farmRun give me an interesting "java.util.zip.ZipException: zip file is empty" message. Any idea, what is this?
