I am having deja vu - last time there were dependency problems when running the ATH against newer versions due to how plugins are loaded when running the ath/mvn vs what the real update center does (which gets the latest with blue ocean). 

Not sure what the solution was last time, but it needs doing again, or we need a better way to run the ATH to more closely represent the real world

To reproduce, build a recent master and then: 

cd acceptance-tests

./run.sh -v=2.46.3 --dev

then open the jenkins that it launches, and check the warnings (big red thing) and note that no blue ocean link appears.

The errors:
