Is it relevant? :/

Fixes a build warning, I can roll it back if you want

Unnecessary duplication?

Hopefully this can replace the duplication in other modules, but I can roll back this project if you'd rather express these flags in each module.

It's useless for local builds. Build cache is good for CI, because on CI, you can grab the caches after build to reuse them in the next run.

Suggested change

org.gradle.caching=true

Please explain how this preview helps.

I added this because it improves the configuration cache experience, at least for me; doesn't need to be in this PR, though. I'll remove it.

What is going on here?

This is a fix from the Gradle team which makes Version Catalog symbols visible within the precompiled build script (the convention plugin). I can add a comment which explains it because otherwise it's pretty mysterious.

CommanderTvis · 2024-02-14T10:28:43Z

build-logic/src/main/kotlin/org.jetbrains.reflekt.conventions.gradle.kts

Any reason why can't this logic be just in a couple of build files? buildSrc and convention plugins were avoided for clarity, preventing mix-up of classpathes and build performance.

I've structured this as a single convention plugin, so that compiler flags are consistent across modules. To use Kotlin 2.0.0 beta, we'll need to pass at least some compiler flags to solve OptIns and allow unstable outputs.

I don't think the flags need to be kept after Kotlin 2.0.0 release, so I can add them to each module.

Please make it so. If we had more modules, of course, a convention plugin would be necessary.

Why do we need all these compiler keys now, considering that everything was fine?

Some of these are needed for Kotlin 2.0, in particular the final two. I will check if the first two are needed.

@CommanderTvis thank you for the quick review, sorry for the mess 😅 we are trying this downstream to see if it works as expected.

With regard to the NoSuchMethodError, here is the exception silenced by that code:

java.lang.NoSuchMethodError: 'void com.intellij.openapi.util.io.NioFiles.deleteRecursively(java.nio.file.Path)'
	at org.jetbrains.kotlin.test.services.impl.TemporaryDirectoryManagerImpl.cleanupTemporaryDirectories(TemporaryDirectoryManagerImpl.kt:45)
	at org.jetbrains.kotlin.test.TestRunner.runTest(TestRunner.kt:32)

I remember now. This deleteRecursively function on com.intellij.openapi.util.io.NioFiles is called by AbstractKotlinCompilerTest.runTest. It seems the Open API dependency for IntelliJ may need to be upgraded, but I don't see where it is being pulled in. Do you have any ideas? Full stacktrace below.

It was being suppressed because it's deleting temporary files, otherwise the tests seem to pass.
