Gatekeeper Issues with Eclipse (running CloverETL) after Installing Mac OS X Yosemite

Right after upgrading my Mac to OS X Yosemite, I'm having trouble using the program CloverETL (which runs off of Eclipse 4.3).

After I start the Eclipse platform, I am receiving a Gatekeeper error for an unidentified developer which reads: "CloverETL Designer.app can’t be opened because the identity of the developer cannot be confirmed”

Any idea how to fix this problem? Thanks!
