Subject [jira] (MSHADE-75) Package maven multimodule project with shade plugin : error in opening zip on directory
Date Mon, 28 May 2012 00:25:21 GMT

This is not a fix for the problem at hand. The patch doesn't change the behavior at all, it
would apply to a case where a declared dependency had a classifier, and the fix would never
work, either.
      was (Author: bmargulies):
    This is not a test case for the problem at hand. The pom supplied creates a classified
jar but does not include it in shade. Instead, it fails, as far as I can tell, because there
are no resources to include in the shaded jar at all. I'm looking further.

> It's due to the shade plugin whose tries to reference first module classes from target/classes
repository instead of the jar file previously build.
> Therefore, it seems that the shade plugin doesn't work with a maven multimodules project.
> I manage to build my maven aggregator project by applying the attached patch (patch-maven-shade-plugin.txt)
