How to create an executable jar with dependency jars

Question

I have created a java application which depends upon some external jars. Now I want to create an executable jar for my project. Which means if I double click the project then it should execute.

Answer 1

You can do that easily with Ant:

<jar jarfile="MyJar.jar" basedir="bin">
    <manifest>
    <attribute name="Class-Path" value="lib/lib1.jar lib/lib2.jar lib/lib3.jar"/>
    <attribute name="Built-By" value="me"/>
    <attribute name="Main-Class" value="mypackage.Myclass"/>
    </manifest>
</jar>

This will add all the appropriate entries to the Manifest file. In order to be able to run the jar, you also need to create a lib folder and place all the dependency jars there:

myjar.jar
lib/lib1.jar
lib/lib2.jar
lib/lib3.jar
