見かけましたよね。

以下に似たようなエラー。

私は、SDKバージョンアップ時に SQLDelight で出会いましたが以下で回避。

// bottom of app/build.gradle.kts

androidComponents {
  onVariants(selector().all()) { variant ->
    afterEvaluate {
      val capName = variant.name.capitalize()
      tasks.getByName<KotlinCompile>("ksp${capName}Kotlin") {
        setSource(tasks.getByName("generate${capName}DatabaseInterface").outputs)
      }
    }
  }
}

こんな「とりあえず回避」ってのよくありますが

対応コードが溜まっていくと後々意味不明になるので

なんか嫌ですけど、

仕方ないんですよね。
