[jira] (MNG-3832) Allow wildcards in dependency exclusions

    [ https://jira.codehaus.org/browse/MNG-3832?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=326011#comment-326011 ] 

Matt Yates commented on MNG-3832:
---------------------------------

This gentleman (Jos Dirksen) figured out what's going on and describes it [on his blog|http://www.smartjava.org/content/maven-and-wildcard-exclusions]
In short, the above discussed {{ExcludesArtifactFilter}} is not even called (at least in Maven 3)
Exclusions checks are instead made by [ExclusionDependencySelector|https://github.com/sonatype/sonatype-aether/blob/master/aether-util/src/main/java/org/sonatype/aether/util/graph/selector/ExclusionDependencySelector.java] which handles the wildcard cases
Basically, the only thing the needs to happen now is clean up of the warnings you get when you try to do this

> I would like to be able to exclude all transitive dependencies from a certain dependencies.  This is especially useful when depending on an artifact with a classifier that may not have the same dependencies as the main artifact.  Currently the only way to do this is by excluding each dependency individually which requires significant effort and is prone to becoming out of date.  The following syntax is one possibility.
> Exclude all transitive dependencies
> {code}
> <exclusion>
>   <groupId>*</groupId>
> </exclusion>
> {code}
> Exclude transitive dependencies with the groupId "org.company"
> {code}
> <exclusion>
>   <groupId>org.company</groupId>
>   <artifactId>*</artifactId>
> </exclusion>
> {code}
