How to Integrate External Libraries into IntelliJ IDEA Artifacts?

Incorporating External Libraries into IntelliJ IDEA Artifacts

To seamlessly integrate external libraries within your IntelliJ IDEA artifacts, ensuring access to their classes, adhere to the following guidelines:

Option 1: Extract Dependency into Artifact JAR

This method bundles the dependent library directly into the artifact JAR:

• In Project Structure, configure the "Output layout" for your artifact.
• Select the "Extract to the JAR" option for the dependency.

Option 2: Link Dependencies via Manifest.MF

• Create a Manifest.MF file in the META-INF directory of your artifact.
• Add the following lines to the file:

Class-Path: <path/to/dependent/library.jar>
Main-Class: <fully/qualified/main/class/name>

• Ensure that all required dependent JARs are placed alongside your artifact.

Example Project

Refer to the "HelloWithDependencies.zip" sample project for a practical demonstration of both approaches:

• "single" directory demonstrates the dependency extraction method.
• "linked" directory illustrates the linked dependencies method.

Artifact Configuration

For both options, ensure the following artifact configurations are in place:

• In Project Structure, under "Modules," add the dependency to the "Libraries" section.
• Under "Output for Artifacts," select the appropriate output directory (e.g., "outsingle" or "outlinked").
