How to generate code across sourcesets

[xgouchet]

I'm trying to generate some code for my tests based on the code in my main sourceset.

If I apply my Processor to the main source sets, it sees the types I want to, but generates the output in the same sourceset, which I don't want because it's not relevant for production, and also it's missing some dependencies which are only available in test.

Is there a way to do so either in my processor implementation or in the project where I apply it? I'm using Gradle, and so far here's how it works

// build.gradle.kts
dependencies {
        add("ksp", "…") // sees the source I want but generates code in either debug/release source set
        add("kspTest", "...") // generates the  code in the debugUnitTest source set, but doesn't see the main sources
}

KSP follows compilation model in Gradle where main and test source sets are compiled separately. So there is no way (that I know of, without hacking Gradle too much) to process main sources together with the test sources. If you have control over the processor, maybe get symbols in main via Resolver.getClassDeclarationByName, Resolver.getDeclarationsFromPackage or through references in the test source set.

Is this similar to my question here?

Yes it does look like we want to achieve the same thing
