[Maven 3.5] hibernate site does not include new hibernate.reddeer plugin; skipTests not working

After switching jobs to use maven 3.5.0, publishing is no longer working – old artifacts are being pulled from JBT site, rather than using locally-built artifacts.

So, hibernate site does not include new hibernate.reddeer plugin, causing this failure in the integration tests site build:

11:54:30 [ERROR]   Missing requirement: org.jboss.tools.forge.ui.bot.test 4.4.100.qualifier requires 'bundle org.jboss.tools.hibernate.reddeer 0.0.0' but it could not be found

Also, the -DskipTests flag is not working.
