Hi all! I was wondering, is checking if the app has some dependency a valid use case when using KSP? Like imagine, if the user of my KSP library has a certain dependency, then I want to generate some classes a bit differently?
I seemingly managed to do this by calling resolver.getDeclarationsFromPackage("com.some.package").iterator().hasNext() , but I was wondering if there is a better/more performant way.

We do this in room, like to use coroutines, you need the ktx artifact.https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:room/room-compiler/src/main/kotlin/androidx/room/solver/binderprovider/QueryResultBinderProviderWithRequiredArtifact.kt;l=29

We use get class declaration by name

I see. Cool, thanks @yigit!
This is a nice validation that I’m supposed to do this and it’s not a hacky approach 😄

[yigit]

Yep. This significantly improves use experience as you can tell them what to add as a dependency, instead of a class not found compilation failure

[Rafael Costa]

In my case, I want to support both cases where he has or doesn’t have a specific dependency.
But actually, now that you mention it, I do have dependencies which I just documented, but if they are not included, then yeah: compilation failure 😛
And we should not rely on documentation only, so.. great! I have more work to do ahah
