1. Run the checkout and ant build steps from the regular JythonDeveloperGuide

  2. In your Eclipse preferences, go to Java > Build Path > Classpath Variables and add a new variable named ANT_HOME that points to your ant install. That directory should have a lib/ant.jar inside of it.

  3. Go to File > Import > General > "Existing Projects into Workspace" in Eclipse

  4. Select your Jython checkout directory as the root

This could be made to work entirely in Eclipse with a few more additions to the external builders. For now, it requires running ant in the first step to make the build/gensrc and build/jarjar directories and then every time after a clean.

Proposed new instructions

Using Eclipse 3.5 + Subversive:

  1. Open the SVN Repository Exploring perspective and create a new repository for the Jython SVN repository.
  2. Open the new repository, expand trunk, right click on Jython, and select Check Out. (You'll be prompted to accept an SSL certificate.)
  3. Once the project is finished checking out, it will show build errors. Right click on the jython-trunk project. Select Build Path > Configure Build Path.

  4. In the Libraries tab, Add Variable > Configure Variables, and add a classpath variable for ANT_HOME.

  5. In the Package Explorer, open the build.xml file under jython-trunk.
  6. In the Outline view, find the "developer build" target. Right click and Run As > Ant Build.

  7. In the Package Explorer view, right click on the jython-trunk project, and select Refresh.
  8. The problems view should no longer show any errors.
