Maven dependency tree different from M2E's Dependency Hierarchy

I'm building a Java Project MaterialsDep that is a plugin for project craftbukkit [loaded in my workspace and a direct dependency of MaterialsDep of type jar and scope compile]. Looking at MaterialsDep's pom's dependency hierarchy in eclipse all jars needed by CB show up as resolved and listed correctly. However running mvn dependency:copy-dependencies on project AP only copies direct dependencies and nothing else.

Running dependency:tree shows:

[INFO] --- maven-dependency-plugin:2.4:tree (default-cli) @ MaterialsDep ---
[INFO] MaterialsDep:MaterialsDep:jar:0.0.1-SNAPSHOT
[INFO] +- org.bukkit:craftbukkit:jar:1.3.1-R1.1-SNAPSHOT:compile
[INFO] +- org.pircbotx:pircbotx:jar:1.7:compile
[INFO] \- org.bukkit:bukkit:jar:1.3.1-R1.1-SNAPSHOT:compile

which are the direct dependencies.

How should I go about ensuring that craftbukkit's dependency are recognized and copied ?

[EDIT]

dependency:tree for craftbukkit:

By configuring the dependency plugin correctly. The property excludeTransitive defines whether transitive dependencies will be ignored or not. Make sure it's value is false.

mvn help:effective-pom might help to find out how the plugin is configured.

[EDIT] copy-dependencies will only copy what dependency:tree shows. As you can see in the output above, craftbukkit itself doesn't have any further dependencies. My guess is that all dependencies in craftbukkit's POM have <optional>true</optional>.

If that is the case, then you will have to mention all of them again in your POM.
