Template for porting GWT modules

[Ahmad Bawaneh]

Hi

For maven we have a template for ported GWT modules to GWT 3.0 here https://github.com/Vertispan/some-gwt-module

It would be realy helpful for gradle experts to provide a template for gradle in order to be consistence.

Thanks

Setting a reminder for tomorrow. I'll see what I can do this weekend.

May i suggest that the template also show how setup annotation-processing since it is almost in every gwt-module that used to have a generator

currently i base my work on gwt-events repository, but when try to build i receive the following error

 gradle build --stacktrace

FAILURE: Build failed with an exception.

* What went wrong:

Failed to notify task execution listener.

> tried to access field org.gradle.api.tasks.SourceTask.source from class com.github.sherter.googlejavaformatgradleplugin.FormatTask

Run with --info or --debug option to get more log output. Run with --scan to get full insights.

The google-java-format plugin is not compatible with Gradle 5.0 (yet, fix has been made, but not yet released). Use ./gradlew, not gradle.
