While writing new and noteworthy for the ESB export I found the following issue:

ESB File > Next

java.lang.NullPointerException

I could only get it to run if I had a ESB project in the project and even then it would select the existing project which is not an ESB - the logic for warnings seem to only work if I actually got a real esb project
