The Line #41 does not works, seems like it can't find Repos.

Pasted the code without this line at my project and seems to have fixed my problem.

Thanks!

Glad to hear it helped! I didn't realize that Repos snuck in here - it's a helper class that I have in my buildSrc to handle configuration-time switching of repositories (ex. using local jcenter cache when [condition], or the Internet version of it when [!condition]) as well as consolidating the logic of restricting what dependencies can be used from a given repository.

Thanks again for the help! I was fighting docker+robolectric combination for some days already... Now my tests are passing at circleCI!

And I ended up using robolectric to change SDK because changing SDK_INT static final does not work after java 11... You know when you discover a bug is actually a matrioska? Like that.

But it is solved, thanks!

@simtel12 That works!

Since the method Repos.jcenter(this.repositories) is not being exposed, I created another version that can be helpful for future reference https://gist.github.com/jairobjunior/d739730a970c622d4634b0c84f0975c7

Thank you!

For anyone that may come to this problem again, it seems that Robolectric 4.5.1 to 4.6 transitioned from android-all artifacts to android-all-instrumented artifacts. These artifacts also have -i3 appended to their frameworkSdkBuildVersion
