Try running: mvn clean, and then do your normal build.
I have to do that occasionally to clear out some old packages after
changing some poms. i.e. internally going from elasticsearch-0.18.6 to
elasticsearch-0.19.12
Deleting your .m2/repository is generally safe. It all gets redownloaded
upon mvn package.
I would as a general rule try to be cleaner about keeping multiple versions
of DSpace laying around. I have a directory OSU builds, one each for
dspace-1.7.x-OSU, dspace-1.8.x-OSU. Then when I'm working with clean DSpace
versions I have dspace-1.8.x-clean, dspace-3.x-clean. I haven't yet done a
proper github-i-fied upgrade from one customized version of DSpace to the
next yet. But thus far to jump from dspace-1.8-custom to dspace-3.0-custom
I've essentially checked out clean versions DSpace (1.8 or 3.0), and then
applied my changes on top of it, typically using 3-way DiffMerge.
I would also try to run a 3-way directory diff against what you've got in
your dspace-1.8 directory, and a clean checkout of DSpace-1.8.x, I'm
thinking you've got some contamination from dspace-3 files.
Good luck
