Node Driver startup issue V1 - driver

Question

I am running into an issue after upgrading a custom cordapp from M13 to V1. I have a small test suite which launches nodes using the node driver, and after upgrading to version 1 I get an issue which seems to be caused by the cordadevcakeys.jks file being null (see the error stack below). To upgrade I simply changed the build gradle release version and gradle plugins version from 0.13.0 to 1.0.0 - I am not sure if there is a step I am missing here that could potentially cause this error? I have also pulled the latests version 1 Corda project locally - although I was under the impression that this step isnt needed.

I can post the code I am using to launch the driver if need be, but by having a look at the cordapp-example it seems my method for starting the driver and nodes is correct, and it was working on M13.
*Edit, added in my gradle build and node driver code

You need to close IntelliJ and clear out your gradle cache (under ~/.gradle on Mac).
