Tekton tasks pipeline with Maven to upload build images

Hi,
Does anyone have experience of building a Tekton pipeline using maven and buildah tasks?

I’m running a simple java springboot app as a proof of concept. Running on an OpenShift platform, but kubernetes examples would be just as good.
I am using the maven task to compile and deploy the code into my Nexus Repo. And then use the buildah task to create a container image.
Thanks,
Sat
