Xtendroid in Android Studio 2

[Toby Kurien]

Xtendroid now works in Android Studio 2. Setup instructions are here:

https://github.com/tobykurien/Xtendroid/wiki/HowTo-setup-Android-Studio-%28aka-Intellij%29-support

The code editing, syntax highlighting, active annotations, etc. all work great! The new 'instant run' feature doesn't work with Xtend though.

Thanks to the Xtend team for the great work on the IntelliJ plugin!

I cannot get it to work reliably. At every rebuild of gradle I get errors like this:

Error during auto build.: Argument for @NotNull parameter 'file' of com/intellij/openapi/vfs/VfsUtilCore.getRelativePath must not be null

Hi Christian,

Could you check that Xtend output folders are exist and if not create them?

It is a known bug and is fixed for 2.9.1: https://bugs.eclipse.org/bugs/show_bug.cgi?id=483931.

Anton
