Select the root of your project and press F4. Then you'll see the project structure. Select the 'Libraries' section on the left hand side and click the plus symbol to create a 'New Project Library'. Choose 'Java' and select the directory where the .class file(s) is located. Proceed the remaining steps by clicking 'OK'.
