Transitive dependecies
Hi all, transitive dependencies can be a real pain when you have a lot of external dependencies in your project. Using exclusions tags is a tedious operation in this case, so I was wondering if a quicker way exists... How can one create a pom module that contains a list of dependencies (let's name it lib pom), so that when the lib pom is added as a dependecy in let's say a war project, the exact list of dependencies from lib pom (no more, no less = no transitivity) are added to the war WEB-INF/lib ? Thanks for your help, Sebastien

RE: Transitive dependecies
Sebastien: On my current assignment, we solved this by having one POM for the main dependencies of all projects, and a child POM called WebDependencies. All child projects of type WAR specify WebDependencies as a direct dependency. This *does* include transitive dependencies -- but you should be able to trim down the list of total dependencies included by a significant amount. (The ones you probably actually need.) If you bundle your WAR in an EAR, you can use this Dependencies POM in both the EAR and WAR projects and suppress everything in the WAR's WEB-INF/lib to eliminate duplication further. Hope that helps.

RE: Transitive dependecies
Hi barrett, I think I'm actually proceeding quite the same (the lib pom I was talking about). I really want to know if I can move a step further and make the dependencies not transitive while included in the WAR (actually an EAR in my case ;-). If the feature does not exists yet in maven (using scope settings or something else), I might ask for it: this is why I want to know if it is already possible or not.

RE: Transitive dependecies
In fact, the dependencies I don't want in the lib directory are the one obtained because of the transitivity mechanism. So I want all dependencies included, but not the one they might have themselves (and I may not have access to the POM of those dependencies to set their scope to provided).

RE: Transitive dependecies
Sebastien: I think most people instead suppress all dependencies from war bundling and then use the maven-dependency-plugin to copy specific artifacts. (It provides more fine grained control at the expense of some extensibility.) It's not a core maven feature, though, as far as I know.

Even if the POM are correct, transitivity can copy much more classes than really needed : you're using library A, which a subset of class uses library B.
