it was happened in using ksp

public fun FileSpec.writeTo(
  codeGenerator: CodeGenerator,
  dependencies: Dependencies
)

the exception stack is

kotlin version: 1.6.21
ksp version: 1.6.21-1.0.5
kotlinpoet version: 1.12.0
gradle: 7.2

Are the versions not suitable?

[ZacSweers]

1.12.0 is built against KSP 1.7.0-1.0.6. You should update your tools.

[kakinIA]

Thanks, it also can downgrade to 1.11.0.

[Nobler]

1.12.0 is built against KSP 1.7.0-1.0.6. You should update your tools.

Could please provide some mechanisms to check the version of ksp that kotlinpoet depending?
ksp can provide some message like this

ksp-a.b.c is too old for kotlin-x.y.z. Please upgrade ksp or downgrade kotlin-gradle-plugin
