Hello all, upgrading to add KSP to my build, instructions here: https://developer.android.com/build/migrate-to-ksp. When doing so I am getting the following error. Anyone else running into this?

java.lang.NoSuchMethodError: 'kotlin.sequences.Sequence com.google.devtools.ksp.processing.Resolver.getPackagesWithAnnotation(java.lang.String)'

Check for new versions...

[Billy Newman]

Bumped my kotlin to 1.9.10. Now:

Unable to load class 'org.jetbrains.kotlin.gradle.plugin.mpp.pm20.KotlinCompilationData'.

[juliocbcotta]

Did you update ksp plugin?

[Chrimaeon]

KSP version and Kotlin version need to align. The KSP version is suffixed with the Kotlin version it supports.

[Billy Newman]

Moving backwards to 1.8.10

kotlin_version = '1.8.10'
...
id 'com.google.devtools.ksp' version '1.8.10-1.0.9' apply false

Still produces the sequence error. Do I have another dependency that ksp doesn’t like?

[juliocbcotta]

just use kotlin 1.9.10 and ksp 1.9.10-1.0.13 , if that is not working, you may have a bigger problem

[juliocbcotta]

if you are using compose, room or dagger ... you may have to update those too

[juliocbcotta]

compose compiler*

Just use KAPT, KSP is so problematic it's not worth the hassle unless you have a specific problem with the KAPT version.

[Billy Newman]

Yeah, I am rolling back to kapt only. Spent 2 days trying to just get room using ksp. Adding ksp dep and updating room dep to ksp and I run into the issues above. This is following the android docs 100%. I will try again at a later time

[Billy Newman]

Just adding ksp dependency I see the issue, without modifying my room dependency. Not sure what “bigger problems” I would have.
