How to Create an Executable JAR from Multiple JAR Files Using Ant?

Merging JAR Files for Executable Usage with Manifest Configuration

The challenge of merging multiple JAR files into a single executable JAR can be easily resolved using straightforward tools.

Using Ant's Zipfileset:

Ant's zipfileset task proves to be an effective way to merge JAR files. The following code snippet demonstrates how to merge multiple JAR files (such as first.jar and second.jar) and place them in a new JAR file named all.jar:

<code class="xml"><jar id="files" jarfile="all.jar">
    <zipfileset src="first.jar" includes="**/*.java **/*.class"/>
    <zipfileset src="second.jar" includes="**/*.java **/*.class"/>
</jar></code>
Copy after login

Setting Main Class and Executability:

In order to make the merged JAR executable, you can make use of a manifest file to specify the main class:

<code class="xml"><manifest>
    <main-class>com.example.MainClass</main-class>
</manifest>
<signjar ...>
    <jar ...>
        ...</code>
Copy after login

Automating the Process:

To automate the process, you can create an Ant script that combines the above tasks and specify the appropriate JAR files and manifest settings.
