How to add external JAR files to an IntelliJ IDEA project? | Projectshop

A step-by-step guide on how to add external JAR files to an IntelliJ IDEA project:

1. Open IntelliJ IDEA: Launch IntelliJ IDEA and open your project.
2. Locate the lib folder: Make sure you have the JAR files you want to add in a directory within your project. Typically, this directory is named lib and is placed in the root of your project.
3. Open Project Structure: Go to the “File” menu and select “Project Structure”, or press Ctrl + Shift + Alt + S (on Windows/Linux) or Cmd + ; (on macOS).
4. Add JARs to Dependencies: In the Project Structure dialog, navigate to “Modules” under the “Project Settings” section. Select your module (usually named after your project) and switch to the “Dependencies” tab.
5. Add JARs: Click on the + button and select “JARs or directories…”. Navigate to your project’s lib folder and select the JAR files you want to add. Click “OK” to confirm.
6. Apply Changes: Click “Apply” or “OK” to apply the changes and close the Project Structure dialog.
7. Verify Changes: IntelliJ IDEA will synchronize the changes to your project. You can verify that the JAR files have been added successfully by checking the project structure or the external libraries section in the Project tool window.
8. Use the External Libraries: Now you can use the classes and resources from the added JAR files in your project’s code.

By following these steps, you should be able to easily add external JAR files to your IntelliJ IDEA project and start using them in your development process.
