  ch.elca.el4j.util.classpath.ClassloaderTools

public final class ClassloaderTools
extends Object

Tool for analyzing the classpath (e.g. in maven projects). This tool allows the list of URLs to be easily retrieved: Call getClassPath(YourMainClass.class). Remark: 'mvn exec:java' uses an URLClassloader for the main class and passes all project dependencies plus the target directories as URLs to that.
