It looks like this is causing failures during dexing in the android-interop test. I think that one may not be run during presubmit.

Seems need to remove the old Dexmaker dependency and add org.mockito:mockito-android

FYI this is the upstream issue: mockito/mockito#1511 It is related to usage of outdated Android tooling. Make sure you are running the latest version of the Android Gradle Plugin.

@TimvdLippe, thanks for the link. That's helpful. So we need to upgrade to com.android.tools.build:gradle:3.3.2. Unfortunately that requires upgrading Gradle to 4.10, which means non-Android is impacted. But since we're on Gradle 4.9 now, it may not be too hard. I'm working on this.

@ejona86 actually I was doing that as well see #5523 #5525
