Error:Timeout waiting to lock buildscript class cache for build file 'E:\xxx\app\build.gradle' (C:\Users\Administrator\.gradle\caches\2.2.1\scripts\build_837c7i6iyyvskowjqvasoz1fk\ProjectScript\buildscript). It is currently in use by another Gradle instance.

I was stuck with this error and had to blow away the contents of my user's.gradle/caches/folder and the contents of my project's.gradle/folder to get going again.

Not sure what caused it, possibly a failed build that kept these files in a locked state?

I'd deleted .gradle/caches/** and it works again.
