makeURLClassLoader

public static final java.net.URLClassLoader makeURLClassLoader(java.lang.ClassLoader parent,
                                                               boolean recursive,

根据libdirs提供的lib路径和classpath创建URLClassLoader实例
如果所有的参数中都没有找URL(jar或class 文件夹),则抛出异常

Parameters:

parent - 指定父类加载器,为null时根据parentLoaderStrategy决定parent

recursive - 指示是否递归搜索文件夹,对 libdirs有效,see also toJarURLs(File, boolean)

libdirs - path列表,path为jar包或jar所在文件夹(such as 'lib')

classpath - jar包或class文件夹路径

Returns:
