Repro:

Use FusedLibraryTest
change the dependency of remoteA to remoteB to have a typo, so that it does not find the transitive dependency: line 86
run the tests.

Expected: a good error message indicating that a dependency is not resolved.

Actual:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':fusedLib1:validateDependencies'.

This can be either an issue with interface method desugaring, most likely one of the dependency has now new static/default/private methods on interfaces which is incorrectly supported by our compiler, or it's an issue with desugared library, or both.

To rule the options out:
- Are you using desugared library in your project (

https://developer.android.com/studio/write/java8-support-table)?
- What is the minSdk of your project? If it's strictly below 24, and you change it to 24, and let us know if the issue happens.

If you want us to help you further, for example by helping you build a work-around, or fix the compiler, we need you to either provide us a reproduction project (github or zip) or a compilation dump of your application (See how to generate dumps here

https://r8.googlesource.com/r8/+/refs/heads/main/doc/compilerdump.md).

Thanks for the report.
