[Jake_nz]

I'm trying to get VrSamples/Oculus360VideosSDK running on my Oculus Go on Mac. I get the following gradle sync error:
ERROR: Could not find method task() for arguments [cleanWorkAround, build_bec9j7f0890u48bvwou5dawsx$_run_closure2@2e2308ea, build_bec9j7f0890u48bvwou5dawsx$_run_closure3@607a128b] on project ':VrAppFramework:Projects:Android' of type org.gradle.api.Project.

Can anyone help please?
