The thing that seems obvious to you, but not to everyone else is that some of the "bleeding" builds are for mcpe-0.12 and some are for PHP7. If you want to run the latest version for 0.12, go to the latest bleeding build. Check the name. If it has "PHP7" in the file name, then go back one earlier. Keep going back until you find one that says "mcpe-0.12" in the file name. The issue is that anytime a new pull request is taken into any line, Jenkins fires up a build on that line, and places it in the bleeding section. So, you see a mixed assortment of PHP7 and mcpe-0.12 builds. The one place that lists all the builds doesn't say which is which. You have to look at the file names!
