daniel carter commented on MNG-2751:
------------------------------------

and an flag to allow merging, as happens for other pom elements.

You should be able to specify

        <resources parent="merge">
            <resource><directory>src/main/licence</directory></resource>
        </resources>

instead of this monstrosity - no wonder maven gets a reputation for verbosity!

        <plugins>
            <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>build-helper-maven-plugin</artifactId>
            <version>1.7</version>
            <executions>
              <execution>
                <id>add-resource</id>
                <phase>generate-resources</phase>
                <goals>
                  <goal>add-resource</goal>
                </goals>
                <configuration>
                  <resources>
                    <resource><directory>src/main/licence</directory></resource>
                  </resources>
                </configuration>
              </execution>
            </executions>
          </plugin>
        </plugins>

>             Project: Maven 2 & 3
>          Issue Type: Bug
>          Components: Inheritance and Interpolation
>    Affects Versions: 2.0.4
>         Environment: All
>            Reporter: Jason Melnick
>             Fix For: Issues to be reviewed for 3.x

> I have an inheritance model as such:
> Parent_POM (General dependencyManagement, pluginManagement, etc)
> |-->Base_POM (global dependency inclusion, default goal, default plugins, etc)
>      |-->Artifact_POM (declares specific artifact type functionality, resources, profiles, etc)
>           |-->Project_POM (project specific dependencies, resources, etc)
> I am attempting to create an hierarchy that will enable a new project to get up and running with very little modification. The issue I am having is if build.resources are declared in the Project_POM they are wiping the Artifact_POM's declarations.
> I think that resources should always be additive. If nothing else add an <inherited> tag a la the plugin element's <inherited> tag. In lieu of that perhaps a resourceManagement section that exposes resource id's that could be selectively added by the child...
