I have the following multi-module project structure as seen within the
maven documentation.
parent
|-pom.xml
|
|-moduleJar
| |-pom.xml
|
|-moduleWar
|-pom.xml
When I build the maven projects at the parent level the latest version
moduleJar is built and then placed in the WEB-INF/lib folder of
moduleWar. If I build, (mvn package) at sub module level within
moduleJar I get a build succesful and only the moduleJar is built, (as
expected). If I build again at the sub module level within the
moduleWar project I get a build failure because it cannot locate an
instance of moduleJar within the repos and tells me to install it
through the standard manual process. This was not expected.
Having set the picture above, I would have expected moduleWar to have
used the information in the parent pom.xml to understand that the
project had to compile moduleJar and then include it within the
WEB-INF/lib folder. If the parentpom.xml file did not reference
moduleJar as a sub module then I would ahve expected Maven to search
the repos. As it standands if I worked within moduleWar with some
plugins, e.g. jetty and tomcat then I need to complete a mvn install
on moduleJar everytime I make a chnage to the sub module so it is
picked up in moduleWar.
I have looked through my archived store of emails from the list and
cannot seem to find the righ answers. I might be searching with the
wrong criteria. Would anyone be able to explain why maven has this
behaviour?
Many thanks
Trent
