Lint options:

    lintOptions {
        lintConfig = file('lint.xml')

        abortOnError true
        xmlReport true
        htmlReport true
        checkDependencies true
    }

Also, our project has custom lint rules. Failure happens with a dependency of 26.6.3 and 27.0.0.

Is any way to downgrade lint runner? This problem is keeping us from using AGP 4.0

Attached slightly different stacktrace for the same problem.

Wonder if disabling some lint rules could help to "fix" this problem, as it is also blocking for us 4.0 AGP upgrade.

Notes:

I suspect the exceptions are happening now because JetBrains recently changed an assert statement into a hard failure (see 3260e41111).

I.e., it's possible that Lint has been hitting this code path all along, and only now it is causing a problem.

This has been difficult to investigate so far because the failure is nondeterministic and also deep inside the Kotlin compiler. Plus, JetBrains seems to be hitting this code path occasionally too (hence why they changed the assert into a hard failure), so I'm not even sure whether Lint is implicated or not.

It could also explain why not all lint rules were working from time to time (https://issuetracker.google.com/issues/149554597). According to Github, this change was done for 1.4-M2, which is considered unstable. Maybe lint runner could use an older but stable version? What else options do I have?

Is any public issue created I could follow?
