Print all files and folders added to java classpath

print class path

  // JAVA
  public static void main(String[] args)
	{
		ClassLoader cl = ClassLoader.getSystemClassLoader();
		
		URL[] urls = ((URLClassLoader)cl).getURLs();
		
		for(URL url: urls){
			System.out.println(url.getFile());
		}
	}
	
	
// GRADLE
testClasses.doFirst {

	println "Test classpath is:- "
	
	sourceSets.test.runtimeClasspath.getFiles().each { file ->
		println "file: \"" + file + "\""
	}

}

Can somebody post a snipped that works for AppClassLoader or for any class loader? I am a java novice.
