Looks like Resolver.getSymbolsWithAnnotation only returns annotations available in the same compilation/gradle module for KMP. When I move the annotation to another module (dedicated to annotations) it's not returned anymore. Have you already experienced something similar ?

Not sure if it's the same issue, but there def is something wonky with annotation resolution on KMP https://github.com/google/ksp/issues/632

Resolver.getSymbolsWithAnnotation only look annotations present in the current compile module, it is not practical to look into dependencies, too.

[Grégory Lureau]

What's the best approach then if I want to write a compiler to cover multiple modules? Should I scan all files? Or copy the annotation in every module?

[Jiaxiang]

in case of a multi module project, can you just apply ksp to all modules and process in every module?

[Grégory Lureau]

Could be enough if I keep everything in 1 git repository/gradle tree but hard to build an open-source compiler I suppose.

[Jiaxiang]

there might be some miscommunication here, you can define annotation in another module, the only requirement is the annotated symbols are defined in the same module where KSP is applied.

[Jiaxiang]

e.g. you can define annotation in lib.jar and use that annotation to annotate a symbol @Anno class C then you should be able to get C by calling getSymbolsAnnotatedWith()

Oh ok, sorry for my english, thanks a lot for your time.
So currently I've a module A for annotation, a module B for the compiler, and a module C with some classes annotated (from A annotation). When I run my compilation, getSymbolsAnnotatedWith() returns nothing, but if I copy/paste the annotation class from A to C (same name, same package), then getSymbolsAnnotatedWith() returns some classes to process.
It's a KMP project so it may be a bit different I suppose, I'd like to define the compiler only for JS, so my gradle looks like this

kotlin {
js(IR) { ...}
// other platforms
sourceSets {
val jsMain by getting {
kotlin.srcDir("build/generated/ksp/jsMain/kotlin")
dependencies {
configurations["ksp"].dependencies.add(project(":ExportCompiler"))
}
}

[Grégory Lureau]

Also I defined the project A as a multiplatform project too, not sure if a classic 'java' library is usable from another KMP module.

[Grégory Lureau]

Mmmh, just realized it's not the same behavior on android platform for some reasons.
Thanks for your comments, I've a lead to investigate!

Looks like some new changes could help in 1.0.1 https://github.com/google/ksp/pull/609
