Subject In Maven how can I recursively build -SNAPSHOT dependencies present in the filesystem but outside the reactor?
Date Thu, 14 Jun 2012 12:49:24 GMT
I have two projects as follows, in neighbouring directories on the filesystem:
*         project_a (-SNAPSHOT)
*         project_b (-SNAPSHOT, depends on project_a)

I'd like to build project_b and for Maven to discover that project_a exists on the filesystem
and thus build it rather than look in the local repo for its artifact.
I could build these within an aggregator and use the reactor to select project_b i.e.
mvn --projects project_b [goal]

However, this is problematic because
*         this two-project example is a simplification of my real build, which consists of
dozens of projects, and I don't want to have to maintain an aggregator project that lists
all of them.
*         I only want to recursively build -SNAPSHOT dependencies

Is there a neat way I could get Maven to perform a recursive build that looks on the filesystem
to find -SNAPSHOT dependency projects and builds them?
I'm familiar with Maven plugin development, but haven't yet found any clues toward a solution
in the Maven / Aether documentation.
