New Gradle Sync is not supported due to containing Kotlin modules using an unsupported plugin version

Question

I'm using android studio 3.4.1 and my Kotlin version is 1.3.31. I have a flutter app. When trying to add cloud_firestore to my app I have the following issue. My android studio Kotlin version is exactly the same as build.gradle. Any advice?

Here is the my buld.gradle:

buildscript {     ext.kotlin_version = '1.3.31'     repositories {         google()         jcenter()     }      dependencies {         classpath 'com.android.tools.build:gradle:3.4.1'         classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"         // for firebase         classpath 'com.google.gms:google-services:4.2.0'     } }

Answer 1

Faced this same error. I had to update my JVM Version in Kotlin Compiler settings.

You can find that setting here: File -> Settings -> Kotlin Compiler -> Target JVM Version

Changing to 1.8 fixed the issue.

Answer 2

Update Kotlin Plugin

I could be that your IDE has an older level of the Kotlin plugin.

Within Android Studio, got to File > Settings... > Kotlin and check to make sure your plugin is up to date. You may see something like this, indicating you need to update:

Also, if you run into memory issues, you may need to add org.gradle.jvmargs=-Xms1024m -Xmx4096m to the gradle.properties file.
