Wrong name message when trying to add an Eclipse workspace/project to Robocode

Problem solved. There may have been more then one thing wrong, but I think at this point, it had mostly to do with which folder(s) I was adding in the Robocode/Options/Preferences/Development Options tab. I believe that initially I misread the label on the tab, and I added just my Eclipse workspace root, thinking it would look for all robots in all projects in the workspace. When that didn't work, I added the project folder that actually contained my robot .class file (e.g. when using "Use project folder as root for sources and class files", then C:\workspace\project\package\class, or when using "Create separate folders for sources and class files", then C:\workspace\project\bin\package\class). I figured out that you must add the project folder that contains the package (which might not always be the project root folder as suggested in the label; e.g. when using "Use project folder as root for sources and class files", then C:\workspace\project, or when using "Create seperate folders for sources and class files", then C:\workspace\project\bin).
