Perform "mvn dependency:tree" *within Eclipse*

Open the pom.xml you want to learn about. This is a multipane editor. One of the panes shows the dependencies and how they are resolved.

Make sure you installed m2e ( previously called as m2eclipse ) plugin. If Eclipse opens pom.xml as plain text, then click the pom.xml and click mouse-right button for pop-up menu. You'll see "Open With" -> " Maven POM Editor". Within Maven Pom Editor, you can check those dependencies in either "dependencies" or "dependencies hierarchy".
