---------------------------------

             Summary: Simplyfied form of overridden scope on transitive dependencies
                 Key: MNG-5540
                 URL: https://jira.codehaus.org/browse/MNG-5540
             Project: Maven 2 & 3
          Issue Type: New Feature
          Components: Dependencies
    Affects Versions: 3.1.0
            Reporter: Tibor Digana
            Priority: Critical


I am thinking of a new feature since Maven's exclusion are two steps process in practice.

In order to change the scope from compile to provided on transitive dependency you exclude dependency via

<dependencies>
 <dependency>
 ...
 <exludes>
  <exclude>
   ... transitive dependency ...
  </exclude>
 </exludes>
 </dependency>
</dependencies>

Then put such transitive </dependency> with scope=provided which was excluded above.

<dependencies>
 <dependency>
 ...
 <scope>provided</scope>
 </dependency>
</dependencies>

This is waste because you have to touch the exc.dependency twice and the POM xml is getting huge.

Maybe another syntax would simplify:

<dependencies>
 <dependency>
  ...
  <includes/>
   <include/>
     ... transitive dependency ...
     <scope>provided</scope>
   <include/>
  <includes/>
 </dependency>
</dependencies>

Validation should fail if no such transitive dependency in includes section is specified for the wrapping dependency.

If the transitive dependency is specified in other sections or inherited, the scopes should be merged.
