This is likely my own configuration / misunderstanding issue and may possibly be an issue using GitSwarm EE.

In a sample Pretested-Integration repo containing HelloWorld.java/HelloWorld2.java files and gradle configuration files I have committed source with a known fatal build issue (redefinition of a final variable) to a */ready/ branch to test the results of the plugin's ability to compile and terminate without pushing to the origin.

In my test the code was pushed to **/ready/VA-Test006 then a merge request was issued.

The build shows the failure, but I still find the source change in the origin/master branch when I examine the commits in the UI and when I clone to a new local repo.

The plugin appears to see the build failure and skip the post-build step:
[PREINT] Build result not satisfied - skipped post-build step.

So I am unclear how I have managed to get the code into the origin/master. I am new to git so it is also possible that I am using terms loosely. Please let me know where I have been unclear.
