URLExtraLoader

or Java extra classpath

URLExtraLoader is a utility that allows you to quickly and easily create a URLClassLoader or work with an existing instance. Functions:

1. Create your own URLClassLoader with dynamic modification of Classpath on the fly and control of resources loaded into Classpath.
2. Extension of the standard URLClassLoader with a wrapper.
3. A utility to work on the fly. It is sufficient to pass a reference to the loader object.

Default way to work with URLClassLoader. In this way, we cannot add files to Classpath.

URLClassLoader classLoader = new URLClassLoader(new URL[]{
        new URL("file:\\test.jar")
});

URLExtraClassLoader

Extra extra = new ExtraURLClassloader(new URL[]{
        new URL("file:\\test.jar")
});

We can now add and remove files to Classpath dynamically.

extra.add(new File("test.jar"));

Example of using the URLClassLoader wrapper

Extra extra = new URLClassloaderWrapper(new URLClassLoader(new URL[0]));
extra.add(new File("test.jar"));

You can also use ClasspathUtils.
Let's create a new instance of URLClassLoader and add a test jar file to Classpath.

URLClassLoader urlClassLoader = new URLClassLoader(new URL[0]);
ClasspathUtils.addToPath(new URL("file:\\test.jar"), urlClassLoader);
