Besides the repository move, I’ve also updated the plugin to work with Gradle’s daemon mode or when the System.console isn’t available which should make it work in Cygwin as well.
I used the “Eclipse Marketplace” tool on a new copy of Juno to install the Gradle and Groovy tooling plugins, then I tried building your project on Eclipse and it does not render any of the “create” tasks that you reference in your document.
Have you tried it on Eclipse or do you only support Idea ?
