Review Comment:
The `sha1` property for CI is usually passed from a command-line. This class
is an extract of everything related to CI Friendly. See, the usage of this
method, it's used in `JDomModel` which does not have Maven project reference.
The goal of `CiFriendlyVersion` is a small clean up without a big
refactoring.
> update-versions removes the CI-friendly ${revisions}
> ----------------------------------------------------
>
> Key: MRELEASE-1109
> URL: https://issues.apache.org/jira/browse/MRELEASE-1109
> Project: Maven Release Plugin
> Issue Type: Bug
> Components: prepare, update-versions
> Affects Versions: 2.5.3, 3.0.0-M7
> Reporter: Marcel Stör
> Assignee: Konrad Windszus
> Priority: Major
> Fix For: next-release
>
>
> Given: a project using CI-friendly versions as per
> [https://maven.apache.org/maven-ci-friendly.html]
> {code:xml}
> <version>${revision}</version>
> ...
> <properties>
> <revision>1.0.0-SNAPSHOT</revision>
> </properties>
> {code}
> If I run {{mvn release:update-versions}} (with or without
> {{{}-DautoVersionSubmodules=true{}}}) I expect the release plugin to change
> the {{$revision}} property. Instead it blindly replaces
> {{<version>${revision}</version>}} with the hard-coded version set on the CLI.
