How to create Java Executable JAR with JAR dependencies 

The following example shows creating an executable JAR file with other JAR dependencies. First create a simple standalone java application, for instance a simple Swing UI application with two dependent libraries (commons-lang3-3.0.1.jar and commons-io-2.1.jar).


File Name  :  
/JavaExeWithLibsTest/ExeJARApplication.java 
   
package com.btc;

import javax.swing.JButton;
import javax.swing.JFrame;

import java.io.File;

import org.apache.commons.io.FileUtils;
import org.apache.commons.lang3.RandomStringUtils;

public class ExeJARApplication {

  public static void main (String [] argsthrows Exception {
    
    //Get Temp directory size in bytes
    long dirSize = FileUtils.sizeOfDirectory(new File("C:/Temp"));
  
    String htmlButton = "<html>Random String : " + RandomStringUtils.randomAlphabetic(6"<br>" +
              "Temp directory size : " + FileUtils.byteCountToDisplaySize(dirSize"</html>";
    
    JFrame frame = new JFrame("My Application");
    frame.getContentPane().add(new JButton(htmlButton));
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    
    frame.setSize(200200);
    frame.setLocation(24090);
    frame.setVisible(true);
  }
}
   

Compile and run the application for sanity.

javac -cp lib/commons-lang3-3.0.1.jar;lib/commons-io-2.1.jar -d . ExeJARApplication.java
java -cp lib/commons-lang3-3.0.1.jar;lib/commons-io-2.1.jar;. com.btc.ExeJARApplication
Create a manifest file manifest.txt with Main-Class attribute. Ensure to enter a new line at the end of manifest file. Otherwise some systems may throw failed to load Main-Class error.
Main-Class: com.btc.ExeJARApplication
Class-Path: lib/commons-lang3-3.0.1.jar lib/commons-io-2.1.jar 

Create an executable JAR using jar command from the console (Ensure to include JDK_HOME\bin in Path environment variable).
jar cvfm [jar-file] [manifest-file] [dirs/files]
jar cvfm test.jar manifest.txt com lib
Run the executable JAR from the console or from "Open with" windows dialog.
java -jar test.jar
It gives the following output,



                    Print
