Robert Scholte commented on MNG-7158:
-------------------------------------
Re-reading the issue, now I see you're talking about the settings.xml, whereas
I thought it was the pom.xml.
But as this property must be solved for a plugin, I expect that this
ModelInterpolator is still responsible for getting the right value.
I need to look at the commit history, because it looks very weird that somebody
implemented it like this.
http://maven.apache.org/settings.html#properties says it should be possible for
properties in the settings.xml, so this looks like a bug.
As the settings.xml is already a system specific file, there's often no need to
use environment variables (as these can be considered constants in general).

> Key: MNG-7158
> URL: https://issues.apache.org/jira/browse/MNG-7158
> Project: Maven
> Issue Type: New Feature
> Components: Inheritance and Interpolation
> Affects Versions: 3.8.1
> Reporter: RH Becker
> Priority: Minor
>
> In *settings.xml*, I'm trying to do something like ...
> {code:xml}
> <profile>
> <id>distribution</id>
> <activation>
> <activeByDefault>true</activeByDefault>
> </activation>
> <properties>
>
> <altDeploymentRepository>my-repo::default::${env.REPO_URI}</altDeploymentRepository>
> </properties>
> </profile>
> {code}
> If I replace {{$\{env.REPO_URI}}} with a literal value, it works.
> I thought maybe I was hitting some general limitation where interpolation
> isn't supported for profile properties, but the [example
> here|https://maven.apache.org/settings.html#properties] makes it seem as
> though they are supported; i.e. this bit ...
> {code:xml}
> <properties>
> <user.install>${user.home}/our-project</user.install>
> </properties>
> {code}
> Is this something that could be supported for alt*DeploymentRepository
> properties?
