I'm having the same issue locally, I can't build.

I've executed the dependencies insight task, and I got:

androidx.test:rules:1.6.1
  Variant runtime:

androidx.test:rules:1.6.1
\--- com.github.bitfireat:synctools:9db5cb5dc6
     \--- standardDebugRuntimeClasspath

So the problem is that synctools is requesting strictly 1.6.1, while we have 1.7.0 in ICSx⁵.

I think the most simply fix would be to downgrade rules and runner to 1.6.1 until we upgrade synctools enough to have 1.7.0
