Unknown error when building for Google VR

I’m having trouble building my project for android even though it was working previously. Here’s my output log from the point where the errors started occurring:

LogPlayLevel: BUILD FAILED

I’ve checked my configuration for building for Android and everything seems well, does anyone have any idea what’s gone wrong? Thank you!
