With version `2.0.0-rc-3`, both `mvn` and `mvnd` now interpolate correctly
`${env.WINDIR}`. I guess the incoherence I noticed with `1.0.2` no longer
exists.
For the sake of it, I also tried with the Windows system property
`SystemRoot` because it has both lowercase and uppercase characters. It looks
like only the full-uppercase syntax is interpolated.
- `pom.xml`
```
