I'm trying to generate a fat-jar. My project uses on logback v 1.1.7 nonetheless one of my dependencies (storm) uses logback but an older version (1.0.6)

I tried shading logback in my project (using sbt shading plugin). Nonetheless it seems that logback tries to load classes dynamically and Im getting the following error from my shaded logback(specifically my shaded logback is trying to create a class using the non-shaded logback):

17:50:43,164 |-ERROR in shadelb.core.joran.spi.Interpreter@29:84 - ActionException in Action for tag [appender] shadelb.core.joran.spi.ActionException: shadelb.core.util.IncompatibleClassException
at shadelb.core.joran.spi.ActionException: shadelb.core.util.IncompatibleClassException

Question are:

Is there a way to have multiple logback versions living in the same class path?
if so can you point out a way/tool to do it without conflicts.
