I am unable to delete the lock file in windows explorer too

Closing my IDE then deleting it manually seems to fix it. I have no clue how to reproduce it other than pressing this on the Minecraft configurations 

Could IDEA be reading something whilst gradle does it stuff?

Figured it out! IntellIJ has a "filesystem watcher" daemon process that opens files up for a split second to verify the contents (and update it in the IDE file list)...

 killing the watcher fixes the error.

To be honest, intellIJ shouldn't be watching files in `.gradle` in the first place

I'll take a look at this.

Maybe I'll take a look at this

Lang is already a PR

Its getting very large though - are package restructuring considered breaking changes? Functionality stays the same?
