> The PR only tackles plugin configuration injection, not model
interpolation. I'll see if/how that can be done...
Actually, this is not the problem. The problem is that the
maven-help-plugin is using the `PluginParameterExpressionEvaluator` and not the
`PluginParameterExpressionEvaluatorV4`. However, after also enhancing the
`PluginParameterExpressionEvaluator` class, the next problem is that
`${session.multiModuleProjectDirectory}` only works on the v4 api, as the
`MavenSession` does not have the `multiModuleProjectDirectory`, which is
deprecated.
After fixing everything that, I do have
```
[INFO] Enter the Maven expression i.e. ${project.groupId} or 0 to exit?:
${session.rootDirectory.uri}
[INFO]
<uri>file:///Users/gnodet/work/git/maven/</uri>
```
> Generic .uri suffix to get the URI representation of any file property

> Project: Maven
> Issue Type: Improvement

> Fix For: 4.0.x-candidate, 4.0.0

>
> It's impossible to properly generate, for instance, a java policy file which
> needs files URIs, using either Cargo properties and filtered config files, or
> just filtered resources.
> In both cases, the problem is the impossibility to generate proper URIs when
> expanding Maven properties (see also MNG-3760).
> The candidate feature is to add a way to explicitly request the URI when
> expanding a property by means of a {{.uri}} suffix. The underlying
> {{getUri()}} method should rely on the correct {{Path#toUri()}} and neither
> {{File#toUri()}} nor {{File#toString()}}, see the SO reference in MNG-6386.
> For instance:
> * {{${project.basedir.uri}}} instead of the broken {{${project.baseUri}}}
> (and of course fix MNG-6436 otherwise it's useless)
> * {{${project.build.directory.uri}}}
> * {{${settings.localRepository.uri}}}
> * etc
