I'm trying to upgrade my plugin from 1.9.10 to 2.0...

# compiler

[Tóth István Zoltán]

I'm trying to upgrade my plugin from 1.9.10 to 2.0.0-RC2. In my test cases I get this error, have anyone seen something like this?

If there is any available information about how to upgrade, please let me know. Thanks in advance.

com.intellij.rt.execution.junit.FileComparisonFailure: Actual data differs from file content:

fun Adaptive.higherFun(higherI: Int, lowerFun: Adaptive.(lowerFunI: Int) -> Unit) {
    higherFunInner(higherI * 2) { lowerFunInnerI ->
        lowerFun(higherI + lowerFunInnerI)
    }
}

fun Adaptive.higherFun(higherI: Int, lowerFun: Adaptive.(lowerFunI: Int) -> Unit) {
    higherFunInner(higherI <!MISSING_DEPENDENCY_SUPERCLASS!>*<!> 2) { lowerFunInnerI ->
        lowerFun(higherI <!MISSING_DEPENDENCY_SUPERCLASS!>+<!> lowerFunInnerI)
    }
}

You didn't provide some dependency to the test runtime classpath

[Tóth István Zoltán]

The error is for the multiply operator between two integers. All I did was to change Kotlin version from 1.9.10 to 2.0.0-RC2. On 1.9.10 everything works well.

You can add ("") to the diagnostic in the testdata and rerun the test to see what exact class is missing

<!MISSING_DEPENDENCY_SUPERCLASS!("")>*<!> 2

[Tóth István Zoltán]

Thank you, I'll try that.

[Tóth István Zoltán]

Hm... I can't add the ("") . This test is not a diagnostic test but a box test that is supposed to be successful. Actually, I get the fir.ir.txt and ir.txt files generated and they do not contain this missing dependency line.

But when I run the test it fails with (in this case it is String.startsWith):

Actual data differs from file content: basic.kt

You can apply te diff with diagnostic to the file even for box tests (temporary)
Or create similar diagnostics test

[dmitriy.novozhilov]

Regarding the issue: K2 compiler become more strict in reporting about missing dependencies

[Tóth István Zoltán]

I can understand that, but these are the very basic Kotlin operators, like multiplying two integers.

Hm:

• cloned https://github.com/demiurg906/kotlin-compiler-plugin-template.git
• run tests, all OK
• changed it Kotlin to 2.0.0-RC2
• run tests, all OK
• changed testData/box/simple.kt
◦ (result == "Hello world") to result.startsWith("Hello world")
• run tests, simple fails with:

Multiple Failures (2 failures)
	com.intellij.rt.execution.junit.FileComparisonFailure: Content is not equal: simple.fir.txt expected:<...en () {

[dmitriy.novozhilov]

I'll check it tomorrow

[Tóth István Zoltán]

Ok, thank you, have a nice evening.

[dmitriy.novozhilov]

I've checked, the tests fails as expected, as both dumps were changed
IDEA doesn't show it nicely, as two file diff assertions is too much for it, but if you remove both dumps and rerun the test, you'll see updated dumps

[Tóth István Zoltán]

Yes, that's my bad, I haven't noticed the generated files (I don't generate them by default).

I've noticed you have a // WITH_STDLIB in the first line of the file, I don't have that. I tried to add it but the error is still there.

I use useCustomRuntimeClasspathProviders to add the shadow jar file I generate with the base library, probably that's not compatible with the changes in the compiler.

I'll try to figure out what's wrong with that. Thx for the help.

[Tóth István Zoltán]

Oh, it wasn't the custom provider, this was the missing part from BaseTestRunner :

+ JvmEnvironmentConfigurationDirectives.FULL_JDK
