Hi, I tried doing a mvn dependency:tree and I get a tree of dependencies.

My question is, My project depends on many modules which internally depends on many spring artifacts. There are a few version clashes. I want to upgrade all spring related libraries to say the latest one (2.6.x or above). What is the preferred way to do this?

Should I declare all the deps spring-context, spring-support (and 10 other artifacts) in my pom.xml and point them to 2.6.x ? Is there any other better method ?

UPDATE : I have removed the extra question about "\-" so my question is now what the subject asks for :)
