I have written a ContainerDescriptorHandler plugin for the Maven assembly
plugin. It works when the module that uses it is built 'standalone'. When
the module is built as part of a large multi-module project I see either
[INFO] : org.apache.maven.plugin.assembly.model.Assembly@13579e0
Assembly is incorrectly configured: null
Assembly: null is not configured correctly: Cannot find
ContainerDescriptorHandler with hint: instructions
Or, even worse,

I have boosted the memory settings to ridiculously high values with no
effect, which leads me to believe I have created some kind of infinite
dependency loop, because many of the other modules also use the assembly
plugin (although without my ContainerDescriptorHandler).
Does Maven have a switch to log the workings of the dependency mechanism as
it does its job?
