This is one of the major differences between Gradle and Maven.  Gradle has
no idea about a "local repository" in terms of publishing.  These jobs, if
they publish, always publish to Nexus.

We added the ability to read artifacts from "Maven local" mainly to deal
with cases where we have local Maven-built projects that we want to have
ORM pick up a local snapshot of.  HCANN was the main thing here.  But the
"Gradle way" is to have the "other" local project (e.g., HCANN) publish its
SNAPSHOT to Nexus and for the ORM build to pick it up from there.

More repeatable builds that way.  You pointed out one such scenario.  Of
course locally, Gradle (with some help usually) also lets you aggregate
these disparate projects together into one cohesive build.

And given that IIRC I converted HCANN to use Gradle for building as well,
maybe its time to pull that ability.


One way would be to actually upload the snapshots to the jboss Nexus,

That is another option for sure.  And actually it does not even have to be
separate invocations.  We could script the creation of a new Test task
based on the configured JDK6 path and just have both run in the same Gradle
build.
