The following worked fine for me, using Eclipse 20110218-0911 (it's old) on OS X 10.9.5. 1. File->New->Java Project. 2. Name your project. I called it "MyProject" 3. Click Next > 4. Click Libraries tab 5. Click "Add External Jars..." 6. Add the mason.18.jar file. 7. Click Finish 8. Select "MyProject" 9. Run->Run As->Java Application 10. Select (for example) AntsForageWithUI 11. Press Okay The AntsForageWithUI demo pops up no problem. To run the 3D demos, add the 3D jars I provided in an earlier message. If you want to do charts and graphs, etc., add the standard library jar files that come with MASON.
