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?

Copy code

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

Bumped my kotlin to 1.9.10. Now:

Copy code

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

Did you update ksp plugin?

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

Moving backwards to 1.8.10

Copy code

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?

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

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

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.

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

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