There is not much we can help with. You might want to post this in a Jenkins forum, where it’s more likely to find others that use maven to build their images the way you try to do.

A quick search on Google like “jenkins net.sf.json.JSONException: null object” can also give you an idea what is happening. It clearly indicates a json error in Jenkins and probably has nothing to do with Docker. Example
