Correct Way To Add External Jars (lib/*.jar) To An IntelliJ IDEA Project

To add external JARs to your IntelliJ IDEA project, you can follow these steps:

  1. Open your project in IntelliJ IDEA.
  2. Create a new directory in your project, such as "lib", and place all the external JAR files you want to add inside this directory.
  3. Right-click on the "lib" directory and select "Mark Directory as" > "Library Directory". This will let IntelliJ IDEA know that this directory contains library files.
  4. Go to "File" > "Project Structure".
  5. In the left panel, select "Modules", and then select your module name.
  6. In the right panel, go to the "Dependencies" tab.
  7. Click on the "+" button to add a new dependency.
  8. Select "JARs or directories…" option.
  9. In the file chooser dialog, navigate to your project’s "lib" directory and select all the JAR files you want to include as dependencies.
  10. Click "OK" to add the dependencies.
  11. Click "Apply" and then "OK" to save the changes.

IntelliJ IDEA will now include the external JARs as part of your project’s classpath. You can use the classes and resources from these JARs in your code without any issues.
