Eclipse - Unhandled Event Loop Exception when exporting custom connector project

Hi there,

 

I'm unable to tell what is causing this but it is proving difficult to debug. Sometimes when I try to export my custom connector via Eclipse I get a Null Pointer Exception (stack trace pasted below).

 

I've yet to discover why this occurs sometimes and not others - has anyone else encountered this?

 

Thank you
