I have two class files: Generator.class(Main) and Approach.class(Helper), which are created when I compile Generator.java code. The code is dependent on two external jars - argparse4j-0.7.0.jar and org.apache.commons.io.jar.

In normal scenario, if I need to execute the code, I would have to run below :

java -cp .:argparse4j-0.7.0.jar:org.apache.commons.io.jar Generator

I want to create a jar file so that it is easy to share a single file.

One approach that I found was, to include below in the jar file (Main.jar) - 1. Generator.class 2. Approach.class 3. manifest.txt

Manifest file : manifest.txt

Main-Class: Generator
Class-Path: argparse4j-0.7.0.jar org.apache.commons.io.jar

In this case, I need to share below 3 with the user - 1. Main.jar 2. org.apache.commons.io.jar 3. argparse4j-0.7.0.jar To run the jar :- java -jar Main.jar

Is it possible to create a single jar file (Main.jar) with below files - 1. Generator.class 2. Approach.class 3. org.apache.commons.io.jar 4. argparse4j-0.7.0.jar 5. manifest.txt

Then only Main.jar needs to be shared with the user and it can be run using : java -jar Main.jar

I gave this a try with the same manifest file as mentioned above but the java command fails to run the jar.

  • Kindly go through the following [link](https://stackoverflow.com/questions/81260/easiest-way-to-merge-a-release-into-one-jar-file) for your required solution. – Mayank Maria Apr 15 '19 at 16:25
  • Thanks for sharing the link. It was very informative. But none of the approach worked for me easily. I looked around and found assemble plugin (maven) which directed me towards using the shade plugin (maven). This was very easy at worked very well. – Garima Agarwal Apr 22 '19 at 13:05
