A warning for Android users. To use Gradle toolchain support, use the Android Gradle plugin (AGP) version 8.1.0-alpha09 or higher.


Gradle Java toolchain support is available only from AGP 7.4.0. Nevertheless, because of this issue, AGP did not set targetCompatibility to be equal to the toolchain's JDK until the version 8.1.0-alpha09. If you use versions less than 8.1.0-alpha09, you need to configure targetCompatibility manually via compileOptions. Replace the placeholder <MAJOR_JDK_VERSION> with the JDK version you would like to use:

android {
    compileOptions {
        sourceCompatibility = <MAJOR_JDK_VERSION>
        targetCompatibility = <MAJOR_JDK_VERSION>
    }
}

gradle을 업그레이드 하거나 싫다면 내가 사용하는 java 버전으로 바꿔주라고 해서 17을 넣어줬더니 됐다.
