Hi,
I'm trying to get the reactor plugin to work for our project structure
(simplified version):
project-root/
/modules
pom.xml
/A
/api
/impl
/B
/api
/impl
/root-pom/pom.xml
The root-pom/pom.xml contains a modules section that just references the
project modules
<modules>
<module>../modules</module>
</modules>
Now, from the root-pom directory I do "mvn reactor-make
-Dmake.artifacts=A-api" which should normally trigger B-api,A-api to be
built. Instead i get
[INFO]
