Description

Ever since upgrading to 1.1.0, I can no longer resolve the install function in my IDE. I can downgrade back to 1.0.1, and everything is fine, but as soon as I upgrade again to 1.1.0, install can no longer be found, which makes most of the other parts of the code unresolve as well. I’ve tried refreshing all the gradle dependencies, which doesn’t seem to fix it either. When compiling with gradle in the command line, the same errors surface as well.

This should be fixed in 1.1.1

For me 1.1.1 solved this.
