Andy Wilkinson commented on MNG-5971:
-------------------------------------

Since that scope would be processed very early (before inheritance and 
interpolation), you cannot use any features like property expansion.

Given that I can do this:

{noformat}
<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>com.example.foo</groupId>
            <artifactId>alpha</artifactId>
            <version>${foo.version}</version>
        </dependency>
        <dependency>
            <groupId>com.example.foo</groupId>
            <artifactId>bravo</artifactId>
            <version>${foo.version}</version>
        </dependency>
    </dependencies>
</dependencyManagement>           
{noformat}

I'd really like to be able to move that dependency management out into a 
reusable bom and do this:

{noformat}
<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>com.example.foo</groupId>
            <artifactId>foo-bom</artifactId>
            <version>${foo.version}</version>
            <scope>include</scope>
            <type>pom</type>
        </dependency>
    </dependencies>
</dependencyManagement>
{noformat}

If the accepted goal for {{include}} is to provide a shorthand for declaring 
the managed dependencies directly, I'd expect that the same rules for the use 
of properties would apply. Is that not possible?

>             Project: Maven
>          Issue Type: Wish
>          Components: Dependencies
>    Affects Versions: 3.3.3
>            Reporter: Stephane Nicoll
>            Priority: Trivial
>
> When a project extends from a parent with a {{dependencyManagement}} section, 
> it is not always possible to properly override (and align) the version to use 
> for a group of dependencies.
> We typically use Bill Of Materials to gather a group of modules and make sure 
> their versions are consistent. 
> The following project demonstrates the issue: 
> https://github.com/snicoll-scratches/maven-dependency-management
> The first commit is a working use case where the parent uses a bom with 
> version A and we use the same bom with version B in the child. Version B is 
> used as expected.
> The second commit demonstrates the faulty scenario. Rather than using a bom 
> in the parent, we use a direct dependency (provided by that bom). We still 
> use the bom with a different version. In that case all the dependencies but 
> the one provided by the parent are overridden (leading to mixed versions for 
> the dependencies provided by the BOM).
> It looks like the distance is still used to compute the version while the 
> graph of dependencies should be flatten at each step for a proper override. 
> Thoughts? Thanks!
