Marcono1234 commented on MNG-7058:
----------------------------------
The "Version Order Specification" section starts with:
{quote}
If version strings are syntactically correct Semantic Versioning 1.0.0 version
numbers, then in almost all cases version comparison follows the precedence
rules outlined in that specification.
{quote}
I chose "gamma" just as example to not make this too contrived; I am not asking
for any special casing for that word.
My point was rather that the complete concept of SemVer pre-releases cannot be
applied to Maven due to the exception outlined above.

> Project: Maven
> Issue Type: Bug
> Reporter: Marcono1234

> Possibly related to MNG-6420 and MNGSITE-387
> The Maven [Version Order
> Specification|https://maven.apache.org/pom.html#version-order-specification]
> says:
> {quote}
> Non-numeric ("qualifiers") tokens have the alphabetical order, except for the
> following tokens which come first in this order:
> "alpha" < "beta" < "milestone" < "rc" = "cr" < "snapshot" < "" = "final" =
> "ga" < "sp"
> {quote}
> It appears the intention of the author was that no qualifier ({{""}}) as well
> as {{"final"}} and {{"ga"}} represent a _release_.
> However, because due to this exception these qualifiers always come first it
> conflicts with [SemVer 1.0.0
> ยง4|https://semver.org/spec/v1.0.0.html#spec-item-4] defining pre-releases:
> {quote}
> A pre-release version number MAY be denoted by appending an arbitrary string
> immediately following the patch version and a dash.
> {quote}
> This can result in situations where a release would come before a pre-release.
> Imagine someone calls their pre-releases _alpha_, _beta_ and _gamma_.
> Version _1.2.0-gamma_ is according to SemVer a pre-release, yet if a release
> _1.2.0_ (or _1.2.0-final_) is released, Maven considers the pre-release newer
> than the release:
> {code}
> java -jar .\maven-artifact-3.6.2.jar 1.2.0 1.2.0-gamma
> {code}
> {code:title=Output}
> 1. 1.2.0 == 1.2
> 1.2.0 < 1.2.0-gamma
> 2. 1.2.0-gamma == 1.2-gamma
> {code}
> This could be solve by specifying that an empty string ({{""}}) = {{"final"}}
> = {{"ga"}} < {{"sp"}} always come after any other qualifier. However, that
> might be a breaking change.
