I recommend using the effective-pom goal of the maven-help-plugin [0] to get
information about the effective POM that Maven ‘sees’, and if you enable
verbose output there will be comments telling you where everything came from:
mvn help:effective-pom -Dverbose=true
I don’t use Eclipse, but in IntelliJ IDEA there are icons in the gutter of the
editor that jump to the place where a versionless dependency‘s version is
declared, which can be helpful too. I don’t know if there is a similar feature
in Eclipse. (The Maven Helper plugin [1] for IntelliJ IDEA is also nice as an
interactive and easier to read alternative to dependency:tree, including a
filtering option.)
