Title: Multiproject builds - org.gradle.api.InvalidUserDataException: Cannot add task ':subproj:decompile' as a task with that name already exists.

Seems to be caused by BasePlugin.project being static and trying to create that all it's tasks in the same project multiple times.

I've tried changing it to a normal field and it seems to at least let the build run, currently testing if it broke anything, will send a PR once i'm sure.

Full error:

```
