Maven and Spring and Liberty - Broken, now fixed

Having followed this Spring / JPA tutorial : -

JPA Tutorials

specifically this: -

Eclipse/JPA Web Application Tutorial

and having deployed the resulting WAR file to WebSphere Liberty Profile: -

~/wlp/bin/server version

WebSphere Application Server 18.0.0.3 (1.0.22.cl180320180905-2337) on Java HotSpot(TM) 64-Bit Server VM, version 1.8.0_181-b13 (en_GB)

I saw this in my logs: -

This had the answer: -

and now we're golden.
