IssueTracker

can you share steps to reproduce same issue.

My first attempt at a simple sample project couldn't repro.  I'll try again and follow up.

I am also getting this issue (or something similar). I am running Beta 2 of Android Studio 3.0.

I also attempted to create a simple test project but failed to reproduce the issue.

I don't know enough about how lint works to know if task execution order is relevant. Based on the times/line numbers of the first occurrences of "module_name:lint" and "module_name:assemble" in the output during dry-runs and actual build attempts after a clean, Gradle seems to execute lint in alphabetical order with little or no regard to the dependencies I declare with ":api" or ":internal". In fact, it may be possible for Gradle to lint a module before its dependencies are assembled in such cases. Again, I don't know if task execution order is relevant. However, if it is, please let me know what I should be looking for.  

Below is my stack trace:

Still seeing this in AGP 3.0.0-rc2.  Working on a sample project to repro.

Attached is a sample project.

Looks like an intellij-core bug that's triggered when a method reference -- whose functional interface method has a method signature similar to its delegate -- is then passed to an overloaded method.

In the attached example:
If you change TestCoordinator#onBackPressed to return void, lint passes.  
If you change HandlesBack#onBackPressed to return void, compilation will fail due to an ambiguous method call.

Hey Tor, any chance a fix will make it into AGP 3.1?

This fell off the radar; it was a crash deep inside IntelliJ Java parsing code, so I filed https://youtrack.jetbrains.com/issue/KT-25298 back then -- but they couldn't reproduce it and it didn't go anywhere.

I took another look today and found the real cause -- https://youtrack.jetbrains.com/issue/IDEA-230923 -- which I've patched locally and confirmed fixes this bug.

This will be included in 4.0 beta 1 (I think; if I'm off by the build cutoff date it will be beta2 at the latest.)
