Find hidden dependencies in Ivy

I'm using Apache Ivy + IvyDE for getting my project's dependencies, which are:

    <dependency org="com.google.guava" name="guava" rev="r08" />

    <!-- logging -->
    <dependency org="org.slf4j" name="jcl-over-slf4j" rev="1.6.1" />
    <dependency org="ch.qos.logback" name="logback-classic" rev="0.9.27" />

    <!-- database -->
    <dependency org="org.hibernate" name="hibernate-entitymanager" rev="3.6.2.Final" />
    <dependency org="org.hibernate" name="hibernate-validator" rev="4.1.0.Final" />
    <dependency org="org.hibernate" name="hibernate-c3p0" rev="3.6.2.Final" />
    <dependency org="mysql" name="mysql-connector-java" rev="5.1.14" />

Sources are the Maven and JBoss (Hibernate) repositories.

As you can see I'm using logback+SLF4J for logging, but for some reason Ivy will download log4j and slf4j-log4j as well, which causes a few small problem in my application.

Is there a way to see why this happens, to see which of the dependencies above depend on log4j? Can I get a dependency graph/tree generated from Ivy/IvyDE?

And is there then a way to prevent this from happening?
