Maven2 dependency management and profiles

voxpop

Bit of a long shot - but maybe someone has come across this before.

Basically I have 3 projects
db
middleware
UI

Everything build using continuum +maven2

I use profiles to create a db-dev and db-release jar. The db-dev.jar has the configuration for connecting to development database. and the db-release.jar has the configuration for production database.

So I have the middleware project with a dependency on the db project (in the pom). If I use the release profile, the middleaware project builds with the db-release.jar otherwise it builds with the db-dev.jar.

Up to this stage all works fine - I can build dev or release versions of middleware and will the get db-dev.jar or db-release.jar depending on the profile used.

Now the UI is a web app and is packaged as a war. Here in the pom, Ive set the profile again for production but what I get in the WEB-INF/lib folder is the middleware-dev.jar,middleware-release.jar and db-dev.jar


It seems that the profile works for the first level of dependencies (although I shouldnt be getting the two middleware jars - but thats a problem for another day), but not the second level.

Anyone got any tips on how to sort this out ?

Solved the issue myself in the end.

What I did was change how the profile was activated (-Denv=prod) and added another dev profile that was activated when no env parameter.

This then gave me the release and dev jars in the final build. What Id assumed was that the dependency in the profile would override a "default" dependence (they are exactly the same bar the classifier) - it doesnt.

Anyway I removed the dependency from the main section of the pom and added the particular classifier to each dependency in the separate profiles.

All works now
