Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.9.9999, expected version is 1.7.1.

    Hallo zusammen,


    ich finde trotz Stunden Suche bei Google und vielen Try&Error in Android Studio leider keine für mich verständliche Erklärung, woher dieser Fehler kommt und wie ich ihn beheben kann.


    Diese Meldung erhalte ich für mehrere Module:

    in Build.gradle habe ich schon einige Versuche unternommen, die aber alle entweder beim Gradle-Sync eine Fehlermeldung ergeben oder im Ergebnis wieder zu der oben zitierten Liste von Fehlern führen.

    Code
    plugins {
//    id 'org.jetbrains.kotlin.android'
//    id 'kotlin-android-extensions'
//    id 'com.android.application' version '8.10.0' apply false
    id 'com.android.application'
    id 'com.android.library' version '8.10.0' apply false
    id 'org.jetbrains.kotlin.android' //version '1.9.9999' apply false
    id 'kotlin-kapt'
    id 'kotlin-android'
}

    Irgendwie muss es doch möglich sein, für die oben aufgeührten Module und für die im Projekt verwendete Kotlin-Version auf einen Nenner zu kommen - ich finde es aber nicht raus, wie ich das machen muss. Kann mit hier im Forum evtl. jemand helfen?

    Werden weitere Informationen / Codeausschnitte benötigt, um mir eine Hilfestellung geben zu können?
