Currently, the mtaBuild step installs the wrong artifact in a spring project making use of the "repackage" feature. This PR fixes that by checking if an ".original" jar file exists and using that instead.
Ensure npm dev dependencies are available after mtaBuild as they are required by certain tests.

Extend mta build step to install maven artefacts after build to allow re-using them in later stages (additional unit or integration tests which might not be running as part of the "build" life-cycle).
