    9. If this is the first time you have created a PyDev project then a dialog box appears informing you that the Python interpreter is not configured. Jython, however, is configured so you can ignore this message. Click Don’t ask again to proceed.

  2. Alternatively you can configure an existing project for Jython:
    1. Right-click on the project in the Project Explorer view and select PyDev > Set as PyDev Project from the context menu.
    2. Click Don’t ask again if the Python not configured dialog box appears.
    3. Select Properties from the Project menu.
    4. Select PyDev - Interpreter/Grammar from the Properties dialog box.
    5. Select Jython as the project type.
    6. Select DS-5 Jython as the interpreter.
    7. Click OK to apply these settings and close the dialog box.
  3. Add a Python source file to the project. The .py file extension must be used to identify this type of script.
