Runnable jar can not be created in eclipse [message #1242713]

I have asked same question in IDE forum, but responses are too slow on that forum. So I am putting it here, please excuse me for that.

I have created a java project in eclipse. This project "ScanFiles" has only one class "ScanAttachedFiles" with main().

When I am using export option for this project, pop up window for selecting launch configuration comes up. But in the selection list, I don't see the project name of "ScanFiles" and class name "ScanAttachedFiles"

I created one project before to test some functionalities and that project comes up in selection list.

I have more than 12 projects in project explorer. I see 12 projects coming up in launch configuration selection list. Is there a limit on number of projects being displayed in selection list ? I commented two classes with main() in one project, but still both of them come up in selection list.
It looks like eclipse is not refreshing properly to take changes.
I did refresh for the ScanFiles project, but still same result.

Please let me know, whats wrong here.
I am using SpringSource IDE, which has eclipse embedded in it. I am not sure about version of eclipse.

Thanks

You have to actually launch the class at least once or manually create a launch configuration for it in order for it to show up in the launch configuration selection list.

Use the Run menu. Select Run Configurations... and fill in the appropriate information in the dialog. This is documented in the Java Development Users Guide provided with the Eclipse Java Development Tools.
