Stephen Connolly commented on MNG-5207:
---------------------------------------
FYI the workaround is to change
{code}
<modules>
<module>app</module>
<module>delegate</module>
<module>ejb</module>
</modules>
{code}
to
{code}
<modules>
<module>delegate</module>
<module>ejb</module>
<module>app</module>
</modules>
{code}
The project sorter will correctly pull ejb ahead of delegate and respects the
order in the modules unless direct dependencies indicate otherwise.
A rule of thumb to avoid this issue is that you should list leaf modules first
and put modules with transitive dependencies last...
Another solution is just to add the dependency of ejb to app and again the
project sorter will sort correctly.
I am currently investigating whether the project sorter is running prior to
dependency resolution. It may be acceptable to resolve ex-reactor dependencies
as early as the project sorter as if they are unavailable we will fail
anyway... though plugins such as shade could make them available later in the
reactor build... perhaps it is acceptable to just produce a best effort sorting
if ex-reactor dependencies are not available when sorting the projects

> Maven 3.0.3 and 3.0.4 RC1 fails to build the projects of the reactor in
> proper order, if a transitive dependency (that is part of the reactor build)
> is overruled in the dependencyManagement section with the current SNAPSHOT
> version. Build order is perfectly calculated with Maven 2.2.1.
