Export Runnable JAR in Eclipse: Step-by-Step

To export a runnable JAR file, you can use the built-in functionality in the IDE (Integrated Development Environment). Here are the steps to export a runnable JAR file using Eclipse IDE:

1. Open Eclipse IDE and make sure that your Java project is already opened.
2. In Eclipse, right-click on the project name and select “Export”.
3. In the “Export” dialog box, choose “Runnable JAR file” under “Java” and then click on “Next”.
4. On the “Runnable JAR File Specification” page, select the launch configuration to export and the location to save the JAR file.
5. In the “Library handling” section, choose to bundle the libraries into the JAR file or to bundle them outside the JAR file and specify their locations in the MANIFEST.MF file.
6. Click on “Finish” to complete the export process.

After completing the above steps, you will obtain an executable JAR file that you can run in the command line or double-click to run your Java application.
