"Embedded error: error in opening zip file" with non-jar dependency
-------------------------------------------------------------------
Key: MSHADE-65
URL: http://jira.codehaus.org/browse/MSHADE-65
Project: Maven 2.x Shade Plugin
Issue Type: Bug
Affects Versions: 1.2.1
Reporter: Tim Williamson
Attachments: pom.xml
I have a project with a dependency on both the jetty jar and the jetty tar.gz
(one for compiling, the other due to details of our build system). I would
also like to make a shaded jar that includes jetty jar. However, the following
exception occurs (to reproduce, do a "mvn -e package" with the attached
pom.xml):

[INFO] [shade:shade {execution: default}]
[INFO] Including org.mortbay.jetty:jetty:tar.gz:6.1.18 in the shaded jar.

If I remove the tar.gz dependency, it shades just fine. Unfortunately, I can't
remove that depend without breaking other stuff. :) Near as I can tell, the
shade exclusion mechanism doesn't provide a way to exclude
org.mortbay.jetty:jetty:tar.gz without also excluding
org.mortbay.jetty:jetty:jar.
Seems like there are at least two possible solutions:
- ignore non-jar dependencies when shading
- provide a way to do more granular exclusion
