Robert Scholte commented on MNG-5900:
-------------------------------------
What's misleading about it? It will be replaced with its value within this
pom.xml, whereas {{$\{project.*\}}} will be replaced with the effective project
value. The comparison with Java's 'this' is quite good, hence that's why I
suggested it.
I don't like the idea of different delimiters, it'll make parsing extra complex
and I don't see advantage of it. Introducing a new variable makes more sense
and {{this}} has been the best name so far.
> early interpolation: support ${this.*} as expression

> Key: MNG-5900
> URL: https://issues.apache.org/jira/browse/MNG-5900
> Project: Maven
> Issue Type: New Feature
> Components: Inheritance and Interpolation
> Reporter: Robert Scholte
> Fix For: Issues to be reviewed for 4.x
>
>
> Right now we have $\{project.\*} which always interpolates values based on
> the final project: "classical" interpolation is "late" interpolation. So it
> is not possible that parent poms can lock values, ie avoid child poms
> override. By adding $\{this} for "early" interpolation, it will be possible
> to have intermediate interpolation.
> If a pomfile depends on a parent, that parent will first resolve all
> $\{this.\*} values for itself. Once the fully inherited pom is there, all
> $\{project.\*} will be resolved.
