Android Studio seems to be stuck at Java 8-CodePudding

I'm trying to update the jdk of an AndroidStudio-App to the newest possible version (From what I've read jdk11).

I have changed the build.gradle to:

compileOptions {
    sourceCompatibility JavaVersion.VERSION_11
    targetCompatibility JavaVersion.VERSION_11
}

The version in the settings seems to be 11:

When I type gradlew --version it seems to be java 18. (The version I would like to use, if it were supported)

But even after multiple reloads, restarts, cleans and synchronizations the IDE still behaves as if I would use Java 8.

CodePudding user response：

I have now found this thread which explains that even the new versions of Android Studio simply don't support all features of Java 11.
