[Building Sakai] Problem with pom.xml at root of edu-services

[Noah Botimer]

Maybe we can start up a FAQ / Troubleshooting Guide?

We've been seeing a lot of these build / deployment / pom problems tripping up some of our most experienced people, as well as newcomers.

There's a lot of complexity in our packaging and it's hard to find good answers, check for (ill-)advised patterns, or debug problems quickly. Burning a half day of senior developer time at a crack on getting a build going isn't really a best practice.

Thanks,
-Noah

After cleaning out everything from ~/.m2/repository/org/sakaiproject and starting to build full sakai version 2.7.1, I find that sections-integrationsupport-1.0.6.jar has been put into my m2 repo.  But when gradebook2 tries to find the sections-api jar, it ends up using ${sakai.edu-services.version} when looking for that jar, and ${sakai.edu-services.version} seems to have a value of 1.1.0-a02 instead of 1.0.6.
