I am attempting to execute a gradle build and keep getting the above-listed error. I have set my default JRE for my environment and the project to a JDK install directory. I tried deleting the project and re-deploying it. I have also edited the [alljava.sh](http://alljava.sh) file so that my JAVA\_HOME and JRE\_HOME environment variables point to the JDK install and restarted and tested it to make sure. Please advise how to correct this issue.

Thanks,
