Can not generate jnijavacpp.cpp and jniNativeLibrary.cpp

I am refrencing gradle-javacpp-android to use javacpp with android studio. After a bit adjust to gradle-javacpp-android, it successfully generated NativeLibrary. But jnijavacpp.cpp and jniNativeLibrary.cpp are not generated.

plugins {
    id 'com.android.application'
    id 'org.bytedeco.gradle-javacpp-build' version '1.5.7'
}

allprojects {
    tasks.withType(JavaCompile) {
        options.compilerArgs << "-Xlint:unchecked"
    }
}

By reviewing the build log, it looks like task javacppBuildCompiler$variantName is not executed. I don't know why, please help me, thank you.

Deprecated Gradle features were used in this build, making it incompatible with Gradle 8.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.
