If i compile from Android Studio Build => Generate signeed App bundle / APK menu option works fine. The ide shows me to select the Key store and the path where i want to store the .abb file. Nice

But now i'm trying to automate this process so i tried to do it from console with the command:

./gradlew bundleRelease

However seems that this do different things as gives me an error:

In my build.gradle i have already (as suggested in other answers):

compileOptions {
    // Flag to enable support for the new language APIs
    coreLibraryDesugaringEnabled true

    sourceCompatibility JavaVersion.VERSION_17
    targetCompatibility JavaVersion.VERSION_17
}
kotlinOptions {
    jvmTarget = '17'
}

The next process will be to set the cert store, etc in the build gradle file, i think that i will be able to do that step.

Any help with the current jvmTarjet problem?
