[WARNING] It is highly recommended to fix these problems because they threaten the stability of your build.
[WARNING] 
[WARNING] For this reason, future Maven versions might no longer support building such malformed projects.
[WARNING] 
[INFO] ------------------------------------------------------------------------

These warnings are slated to be removed in version Maven 3.2, but it may still be worth removing the wildcards at this point.

Allow wildcards in dependency exclusions
http://jira.codehaus.org/browse/MNG-3832

I also noticed that artifacts from org.sonatype.sisu.inject are being excluded even though after removing the wildcard exclusion none are shown with

$ mvn dependency:tree -Ddetail=true | grep sisu -

and none are listed by the maven-shade-plugin when building the jar.

All automated tests passed.
