Back to be running again, but seems to have test errors 

[ERROR] There are test failures.

The same problem with reactor summary as in server. There are test failures but reactor summary says everything was build successfully.
Does it smell like tycho 0.18.0 issue?
It's not an issue, it's how we configure job on CI.
In order to have jobs continuing to run tests after a failure and get maximal feedback and distinguish RED and YELLOW, we use the -Dmaven.test.failure.ignore=true and -Dmaven.test.error.ignore=true (don't try it at home or at school!). So the job continue after a test failure, runs following test suites and so on, and in the end says "BUILD SUCCESSFUL" independently of test results.
Then the Jenkins JUnit plugin looks at test reports to check how tests behaved. This Jenkins JUnit plugin then decides to make job BLUE or YELLOW according to test results.
