Here's the confs for a module I depend on: runtime web extends runtime
"runtime" represents the jars to be added to the EAR. "web" represents the compile classpath for the module. Web must extend runtime because I want the jar set of runtime and web to be binary compatible and resolve conflicts. I would like to do the following in my target module: webPackaging->web,!runtime "webPackaging" represents the jars to be added to the WAR. !runtime means do not add any jars from the runtime conf. Is there a way to do this with Ivy? Thanks, Chris Nokes
