    @Override
    public void run() {
        System.out.println("plugin executed");
    }
}

Another Jar project (pom.xml)

JarPlugin initialized

public class Main {
    public static void main(String[] args) {
        
        JarPlugin<InterfaceClass> jarPlugin = JarPluginManager.builder(InterfaceClass.class)
                .setEntryName("Plugin-Entry")
                .setDisabledPluginSuffix(".disabled.jar")
                .build();

        // Get InterfaceClass from sample.jar
        Optional<InterfaceClass> interfaceClassOptional = jarPlugin.loadJar(new File("/home/sample.jar"));
        
        // Get the InterfaceClass list from /home directory
        List<InterfaceClass> interfaceClassList = jarPlugin.loadJarDirectory(new File("/home"));
    }
