[Building Sakai] Nightly2 trunk build broken?

My trunk build failed in the same manner as nightly: site-manage-hbm
failing to resolve the site-manage-api artifact. I started with a
thoroughly empty repo and attempted a build using Maven 2.1.0. I
don't have any definitive answers as to the cause of the build failure
but reviewing the org/sakaiproject portion of .m2 reveals some
I. kernel <parent> variations
The typical trunk Sakai module inherits it kernel dependencies from
the /master/pom.xml, currently kernel-1.1.0-beta02-SNAPSHOT. However,
a sakai-standard-tool pom has been developed and common and search
snapshots rely on it for kernel and other inherited dependencies. The
sakai-standard-tool pom, both 2.7.0-SNAPSHOT and a 2.7.0-build01
release rely on the kernel 1.1.0-beta01 release for inherited
dependencies. So common and search pull in an alternative subset of
kernel artifacts including the component-manager, api and util. At a
minimum these projects are pulling down redundant artifacts, bloating
local repos unnecessarily. Perhaps the inclusion of alternate
versions of the kernel in trunk code are causing other problems.
I recommend that we keep all trunk projects synced to a single kernel
version, snapshot or otherwise. I also recommend that the sakai-
standard-tool snapshot artifact that trunk common and search rely on
have its pom <parent> updated to kernel-1.1.0-beta02-SNAPSHOT to
eliminate, at least for now, trunk variations in kernel dependencies.
I also recommend harmonizing both trunk common and search snapshots
base pom <parent> to the same updated snapshot version of sakai-
II. Lingering M2 dependencies
The M2 dependencies downloaded during a trunk install is due, as David
Horwitz noted earlier, to one or more tool projects relying on old RSF
dependencies. Samigo is the culprit here. It still relies on RSF
0.7.2, which has dependencies on the old M2 master and sakai-util
projects. I recommend that Samigo update it's RSF dependencies; we
might also consider adding an explicit <exclusion> to block these
