I/O / Streams :: Unable To Read File Using Google Guava Resource Library In JBehave Project

I'm getting an IllegalArgumentException returned when I try to get a file using guava library.

I previously had the function working when the file was in a different location, before I switched to running JBehave, my steps run but it fails to find the resource, even after I've moved it.

The code being executed is (this worked previously before using JBehave):

String xMLTemplateFileName = "OBOE-confirmation"
public static void setXMLTemplateFile(String xMLTemplateFileName) throws IOException {
URL url = Resources.getResource(xMLTemplateFileName+".xml");

The file I'm looking for is in the root folder for src/main/resources and also src/test/resources, previously I had it within a completely different location before I switched over to JBehave. I've tried it within a subdirectory in the same locations too.

I've recently updated the pom.xml to try to include the location required.

Extract from pom is below:
