The binary version of its metadata is 1.7.1, expected version is 1.5.1. How to Solve?-CodePudding

I connected firebase and I got this error, how can I fix it? (Class 'com.google.firebase.auth.ktx.AuthKt' was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.7.1, expected version is 1.5.1.)

build.gradle

buildscript {
    ext {
        compose_version = '1.1.0-beta01'
    }

    dependencies {
        classpath 'com.google.gms:google-services:4.3.13'
    }
}// Top-level build file where you can add configuration options common to all sub-projects/modules.
plugins {
    id 'com.android.application' version '7.2.1' apply false
    id 'com.android.library' version '7.2.1' apply false
    id 'org.jetbrains.kotlin.android' version '1.5.31' apply false
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

CodePudding user response：

Try downgrading kotlin version from 1.7.1 to 1.5.1. Your current version is causing the issue as firebase auth dependency is not compatible with your current kotlin version.

CodePudding user response：

In your project level open build.gradle file, increase the ext.kotlin_version from whatever current version that you have to the latest stable version 1.7.10.

You can get latest version from here:

Recently i had same issue,

I fixed with below steps.

Project Gradle

 classpath 'org.jetbrains.kotlin:kotlin-gradle-plugin:1.7.10' 
 or 
 id 'org.jetbrains.kotlin.android' version '1.7.10' apply false

App gradle

implementation "org.jetbrains.kotlin:kotlin-reflect:1.7.10"

You can find more details on the below thread. Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.5.1, expected version is 1.1.15
