Well, there ARE ways to do it, but it's very hard to do and it's very fragile so for all intents and purposes, the answer is no. But that's not a bad thing. It's a good thing and was specifically designed to be that way. Couple of reasons: 1) Ease for developers - when I need to update a dependency version, I just change the version number in my pom and run "mvn install" and mvn does the rest to test to see if it will work. The old way of going off to download their distribution, unpacking it, replacing the jars in my lib dir, checking the other jars in the distribution (maybe the new version includes/depends on newer versions of other things), possibly updating the build scripts, etc... really sucks. For example: you are currently using mina version 1.0.0. I see 1.0.6 was released yesterday. To see if qpid works, just update your top level pom to 1.0.6 and run. There's also a 1.1.3 released yesterday. Again, update and try it. (I assume 1.1.x might have more API changes that may require more work). If I want to try the 1.0.7-SNAPSHOT builds, that's easy too. 2) Ease for your users - related to (1). If you do a "mvn deploy", all your artifacts should then be in the repo. I could depend on qpid-client only and I'd get everything that qpid-client needs automatically. If you have a pom pointing at a local file not in a repo, I would then also have to go off to figure out where the hell that file is and also do all the "magic" to get mvn to use it. It cycles down from there. Lets say I then deploy new artifacts. My users would then also have to find the jar, etc... They may not know that I even use qpid. They would just complain and bitch at me for something you started. If the poms accurately describe all the dependencies and the dependencies are all available, mvn make it easier for you as well as projects that depend on you. (if they also use mvn or the mvn extensions to ant or Ivy, which all would use the repositories) -- J.
