Getting an error when trying to run an app in eclipse.

Hi All, I'm trying to debug the code in a workflow java action, so I've installed the latest release of eclipse, deployed the project for eclipse from within the business modeler (6.10.12). Each time I try to run or debug the project in eclipse I get an error and my app fails to start.   Could use some help in progressing this. Thanks.

If you have tried all the recommended deployment cleaning etc... One reason may be that  one of the setting in the modeler gets corrupted. 

Create a new one by typing it manually - DO NOT use duplicate.
