Deploying a sample project on jube (fabric8) fails - hawtio

Question

We are running Linux RHEL v6.4 where we have Jube 2.0.33 installed. Jube is running with below env vars set
export https_proxy=
export http_proxy=
export DOCKER_REGISTRY=
export KUBERNETES_MASTER=
export FABRIC8_CONSOLE=
Now, we are using below command after setting above env vars to build simple project (contained at quickstarts-master\quickstarts\java\simple-mainclass - from Github samples)
mvn clean install jube:build fabric8:json fabric8:deploy
The build becomes successful, however when we go to jube fabric8 hawtio console and try to run application... we don't see pods running... instead we see below stacktrace printed on jube server console.
Stack trace says the built image is trying to be uploaded to external maven repos which we don't want.... we tried setting "upload" xml element in maven to "false" too.... however still no luck, we end up seeing same stack trace.
