We got an issue on Buildbot because of a Puppet misconfiguration which was always using the port 8080. Pre-gradle OFBiz tests were still running fine on Buildbot.
Before the Puppet misconfiguration fix by infra (
INFRA-13402), to bypass this issue I tried last weekend to use portoffset in Gradle versions. From the documentation, it's theoretically possible but does not work.
Taher suggested, to get back to the previous behaviour were tests were not using/blocking the 8080 port, and to have a look into Config.java...
It's a regression because it was nice to not have ports blocked during tests, as it was before Gradle. So you can use another (or more) OFBiz instance while running tests, and vice-versa.
