Subject Re: Why would maven download a pom and not a jar?
Date Wed, 11 Mar 2015 05:51:55 GMT
Well, in that case, since you're asking for the dependency:tree I'm even
surprised there's any jar downloaded. Maven would only need pom to compute
that. Downloading Jars is only done when needed (say for compiling, etc.)

Btw, do you really type "mvn dependency:tree pom.xml" ? What do you expect?
The "pom.xml" part is gonna lead to an error since pom.xml is not a goal
and that's what's supposed to be listed after mvn.

As for your question: I suppose oro is a transitive dependency of one of
the things you depend on. mvn dependency:tree should generally show it btw.
