installNativeImageClassLoader

public static ImageClassLoader installNativeImageClassLoader(String[] classpath,
                                                             String[] modulepath,
                                                             List<String> arguments)

Installs a class loader hierarchy that resolves classes and resources available in classpath and modulepath. The parent for the installed ClassLoader is the default system class loader (jdk.internal.loader.ClassLoaders.AppClassLoader and sun.misc.Launcher.AppClassLoader for JDK11, 8 respectively). We use a custom system class loader NativeImageSystemClassLoader that delegates to the ClassLoader that NativeImageClassLoaderSupport creates, thus allowing the resolution of classes in classpath and modulepath via system class loader.

Parameters:

classpath - for the application and image should be built for.

modulepath - for the application and image should be built for (only for Java >= 11).

arguments -

Returns:

NativeImageClassLoaderSupport that exposes the ClassLoader for image building via AbstractNativeImageClassLoaderSupport.getClassLoader().
