Support a Prefix v1.0.0

[ChrTall]

What happened?

The Regex does not allow using a prefix like v1.0.0.

What did you want to happen?

I would like to prefix my releases with v1.0.0 and use 1.0.0 as the version.
Prefixing a release with v + semantic versioning is recommended by Gitlab.
Is there a way to override the regex, or could you consider adding the possibility to use v1.0.0 instead of [email protected] ?

I would propose even more broadly that having a restriction at all on what the prefix can be is unnecessary. Why restrict how people name their git tags?

EDIT: Looking at the code and tests in this repo it seems the widely used prefix "v" for version tags has been very deliberately forbidden. If anybody knows why then I would be very interested in hearing the reasoning behind this decision.

FWIW, I'm using this workaround for tags following the pattern name/v0.0.1:

// only populate the version from the git tag if it hasn't been set
if (project.version.toString() == "unspecified") {
    apply(plugin = "com.palantir.git-version")
    val gitVersion: groovy.lang.Closure<String> by extra
    val versionWithV = gitVersion(mapOf("prefix" to "${project.name}/"))
    // strip the leading v from the version
    version = versionWithV.replace("v", "")
}

...but it irks me every time I look at it.
