major version 53 is newer than 52, the highest major version supported by this compiler. Android studio

Question

I got a warning while I compile it tells me :

> Task :app:compileDebugJavaWithJavac
warning: C:\Users\bleuc\AppData\Local\Android\Sdk\build-tools\30.0.1\core-lambda- 
stubs.jar(java/lang/invoke/LambdaMetafactory.class): major version 53 is newer than 52, the highest 
major version supported by this compiler.
It is recommended that the compiler be upgraded.

How can I resolve this? I'm using android studio.

In my module:app

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

I know 53 is java 9 so I tried to pout 1_9 but it shows me so much errors.

Up! I don't know how to correct this on Android studio

Well, i updated my buildToolsVersion in build.gradle (app level, eg Module: YourApp.app) "30.0.2" and the warning disapeard.

apply plugin: 'com.android.application'

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.2"

    defaultConfig {
        applicationId "com.app"
        minSdkVersion 20
        targetSdkVersion 30
        versionCode 1
        versionName "0.0.1"
    }

    ...
}

Let's take Windows as an example, if your OS's JRE is Java 8 (52), while your program is complied in Java 14 (58), you will face a similar error. However, if you specify the program to run with JDK 14 binary, it will run normally.

In short, check what your system default JRE is, if it's older than the one you use to compile, you will have this error. Note that you might not face any issue in IDE since you set your IDE to use newer version of JRE.

Make sure to properly associate the .jar file with the supported JRE, so it will you the correct JRE to run the executable.
