Error: Could not resolve com.android.tools.build:gradle:8.3.2

Beginne damit nachzuverfolgen, wie die Version des Android Gradle plugin aus package.json version_info in platforms/tempPlugin/core/build.gradle etwa bei Zeile 40 ausgewählt wird; vergleiche diesen Pfad mit before-plugins.gradle. Reproduziere den Kompatibilitätsfehler mit Java 8 und überprüfe anschließend, dass die angeforderte Überschreibung berücksichtigt wird und der Android-Build erfolgreich aufgelöst wird.

Environment
My app.gradle:

// You can add your native dependencies here
dependencies {
//  implementation 'androidx.multidex:multidex:2.0.1'
}

android {
    compileSdkVersion 34
    buildToolsVersion "34"
    defaultConfig {
        minSdkVersion 23
        targetSdkVersion 34
        generatedDensities = []
    }

    aaptOptions {
        additionalParameters "--no-version-vectors"
    }
}

and before-plugins.gradle:

// this configurations is loaded before building plugins, as well as before building
// the app - this is where you can apply global settings and overrides

project.ext {
    // androidXAppCompat = "1.4.1"
    // androidXExifInterface = "1.3.3"
    // androidXFragment = "1.4.1"
    // androidXMaterial = "1.5.0"
    // androidXMultidex = "2.0.1"
    // androidXTransition = "1.4.1"
    // androidXViewPager = "1.0.0"

    useKotlin = true
    kotlinVersion = "1.6.0"
    androidBuildToolsVersion = "8.4.0"
}

Describtion
During building I get the following error and nothing changes even when I add androidBuildToolsVersion = "8.4.0" to before-plugings.gradle:

BUILD FAILED in 855ms
Failed to build plugin @nativescript/core : 
Error: Command gradlew.bat failed with exit code 1

Both version seems the be hardcoded here: https://github.com/search?q=repo%3ANativeScript%2Fandroid%208.3.2&type=code and the androidBuildToolsVersion = "8.4.0" does not have any effect on the version. In the error message and under platforms/tempPlugin/core/build.gradle on line 40, it shows always the version 8.3.2: classpath 'com.android.tools.build:gradle:8.3.2'. It seems to come from package.json version_info. I tried Java 1.8, 11 and 23.

I would like to be able to override the gradle version number, so that I can resolve the error.
