In a compiler plugin, I want to generate new source files by interpreting already-existing source files (basically exactly like an annotation processor would) but while getting access to the resolved descriptors coming in from external sources (e.g. if there's a KtCallExpression to let from the stdlib, I want to get the descriptor for that call). I do realise that I can get the bindingContext and use that to call ktExpression.getResolvedCall but obviously I don't have access to that inside of a CollectAdditionalSourcesExtension so what can I do here? I'm thinking maybe I can run analysis twice or something as in run it once inside of a CollectAdditionalSourcresExtension and generate the files and then let the compiler do its own analysis normally but is that the right approach?

Hi @Youssef Shoaib [MOD] I believe what you want can be currently done with RetryWithAdditionalRoots as analysis result in which you launch a new analysis with the new files you’ve generated but that is part of the api that may go away with FIR. @shikasd has a clean example 🙏 of that API here https://github.com/ShikaSD/kotlin-compiler-plugin-retry-with-additional-roots/blob/master/compiler-plugin/src/main/kotlin/Plugin.kt#L30

Kapt also depends on it https://github.com/JetBrains/kotlin/blob/29b23e79f32791e456a5b4a453277f0f0b3e984d/[…]kapt3-compiler/src/org/jetbrains/kotlin/kapt3/Kapt3Extension.kt
