I get the unable to launch message when I try to run my first program. I have gone thru installing Eclipse instruction and I am at a lost as to what do to. I am on Luna and there is a screen shot included.

A sequence of screen captures would help diagnose the problem. In other words what is being done to "launch" the class.

One thing I do see is that there is no "main()" method. Therefore "Run As" Java Application should have issues.

Still working on my issue, I have noticed the the Karel program will not run as a application. Not sure how to force Eclipse to see the projects as application, not an app.

Have you tried adding a main() method?

I could be wrong, but for me that seem to me to trigger eclipse into seeing a class as a java application.

I am following the Stanford CS106a course, I just started and the whole process is very streamlined. "Main Method" is something I do not understand yet but I have been researching it. While I have been trying to start this program, I some how forced Eclipse to only see it as an app. Uninstalling Eclipse did not fix the issue so there must be a preference file somewhere that is holding this whole thing up. If I can some how get back to a clean start, I suspect that my problem would be gone.

I have an addendum, I noticed errors messages and not sure what they mean.
