"Provided" scope transitive dependencies required + exclude dependencies for 
runtime scope only
-----------------------------------------------------------------------------------------------

         Key: MNG-1978
         URL: http://jira.codehaus.org/browse/MNG-1978
     Project: Maven 2
        Type: New Feature

  Components: Artifacts and Repositories  
    Versions: 2.0.2    
    Reporter: David Boden


Why are provided scope dependencies not transitive?

I have several examples in my project where I need to declare a dependency as 
on the compilation classpath but not on the runtime classpath and I need it to 
be transitive. I don't want the dependency to be packaged up in my deployment 
artifact but my entire multi-project hierarchy relies on the dependency.

At the moment, I have to workaround the problem, mostly by declaring duplicate 
provided scope dependencies in multiple projects.

If there's a well-known answer to this query then apologies, could it be placed 
in the "Introduction to Dependency Mechanism" documentation.



I would also be able to model my dependency structure more accurately if I 
could <exclude/> a dependency from the runtime classpath only and keep it in 
the compile classpath.

E.g. 

    <dependencies>
        <dependency>
            <groupId>SalesStation</groupId>
            <artifactId>cds_ss_shared</artifactId>
            <version>SNAPSHOT</version>
            <exclusions>
                <exclusion>
                    <groupId>SalesStation</groupId>
                    <artifactId>ss_base_shared</artifactId>
                    <!-- I want to be able to do this: -->
                    <scope>runtime</scope> <!-- Exclude from runtime classpath 
only, not compile classpath -->
                </exclusion>
            </exclusions>
        </dependency>
    </dependencies>
