don't unzip the jars (maven-assembly-plugin mode)

[eed3si9n]

originally reported by @rollinsruss

steps

1. add deps to "org.jboss.netty" % "netty" % "3.2.3.Final, spring etc.
2. assembly

problem

the license folder, *.handlers, etc gets wiped out under META-INF.

expectation

That being said, I keep coming back to thinking about the Maven assembly plugin that applies an alternative approach to unzipping everything and simply shoves the jars into an embedded lib directory and updates the manifest so the classpath is complete--which avoids this problem altogether and maintains pristine isolation. Perhaps that approach could be a future alternative task on this plugin (wish I had time to help, as it has me quite intrigued).

This is more complicated than I thought (requires custom class loader), and there's sbt-one-jar that does it already.
