My compiler plugin module uses Kotlin 2.2.20, but when I run my test fixtures, I get the error UNSUPPORTED_FEATURE: The feature "break continue in inline lambdas" is only available since language version 2.2 (36,36) in /withoutState.kt. Does anyone know why this feature isn't working?

EDIT: Apparently AbstractIrBlackBoxCodegenTest pins the language version to 1.9. Not sure why. The way to suppress the diagnostic is to add // LANGUAGE: +BreakContinueInInlineLambdas to the test file.

You can also set the language version, I believe. I never ran into this, though, which is strange. I have tests that use context parameters, which weren't a thing pre K2 at all.

Do not use AbstractIrBlackBoxCodegenTest. It's a test runner for the old K1 compiler.
The proper runner you need is AbstractFirLightTreeBlackBoxCodegenTest.

@dmitriy.novozhilov Even when testing a purely IR plugin? Does the FIR backend do everything needed in both IR and bytecode?

Yes.You have to go thru some frontend no matter what. The original Kotlin frontend does not support any language features past 1.9.
