How to Include External Libraries in a JAR Exported from Eclipse

When creating a Java project that utilizes external libraries, it becomes necessary to include them within the project's final JAR file for proper execution. Eclipse provides several options for accomplishing this task.

To create a JAR with external libraries included, follow these steps:

1. Right-click on the project and select Export -> Runnable JAR File.

2. In the "Options" tab, choose the desired packaging method:

   • Copy required libraries into JAR: This bundles all necessary JAR files with your main application.
   • Eclipse Reusable JAR: Exports libraries as individual JAR files alongside the main application, ensuring dependency management for other Eclipse projects.
   • Extract required libraries into generated JAR: This extracts the dependencies from your external library folders into the generated JAR.
3. Select the "Launch Configuration" dropdown to specify the class with the main method.
4. Click Browse to select any additional dependencies located within your project folder.
5. By default, Eclipse includes the libraries listed in "Build Path -> Configure Build Path".

For projects managed by external dependency management tools like Maven, you cannot directly include libraries from them. Instead, the libraries will need to be referenced within your project's classpath.
