GWT, Eclipse Plugin how to rename project along with .gwt.xml file? Am getting error when try to do so

I've spent a while searching on this and nothing that I find seems relevant specifically to my issue. I am making RPC calls so I wanted to change the path to one of my web services.

It was something like mytestproject and wanted to change it to finalprojectname

I went to the mytestproject.gwt.xml file and changed to

I then ran it through and got an error that [ERROR] Unable to find 'org/ediscovery/gwt/mytestproject.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source?

I then changed mytestproject.gwt.xml to finalprojectname.gwt.xml but still got the same result.

I've looked through every possible file and can't find why it thinks the project is still named mytestproject. I have cleaned and rebuilt the project, etc but still the same. I am still fairly new to Java so maybe I am missing something obvious. I would greatly appreciate if anyone can offer any advice. Thanks
