> Maven version sorting is internally inconsistent
> ------------------------------------------------
>
> Key: MNG-6964
> URL: https://issues.apache.org/jira/browse/MNG-6964
> Project: Maven
> Issue Type: Bug
> Components: Core
> Affects Versions: 3.6.3
> Reporter: David M. Lloyd
> Assignee: Dennis Lundberg
> Priority: Major
> Fix For: 3.8.2, 4.0.0-alpha-1, 4.0.0

> There's a bug where version sorting is inconsistent. This manifests like this:
> {code:java}
> $ java -jar ~/local/apache-maven/lib/maven-artifact-3.6.3.jar 1-0.alpha 1
> Display parameters as parsed by Maven (in canonical form) and comparison
> result:
> 1. 1-0.alpha == 1-0.alpha
> 1-0.alpha == 1
> 2. 1 == 1
> $ java -jar ~/local/apache-maven/lib/maven-artifact-3.6.3.jar 1-0.beta 1
> Display parameters as parsed by Maven (in canonical form) and comparison
> result:
> 1. 1-0.beta == 1-0.beta
> 1-0.beta == 1
> 2. 1 == 1
> $ java -jar ~/local/apache-maven/lib/maven-artifact-3.6.3.jar 1-0.beta
> 1-0.alpha
> Display parameters as parsed by Maven (in canonical form) and comparison
> result:
> 1. 1-0.beta == 1-0.beta
> 1-0.beta > 1-0.alpha
> 2. 1-0.alpha == 1-0.alpha
> {code}
> Thus there is no correct total order: {{1-0.beta > 1.0.alpha}} even though
> both {{1-0.beta}} and {{1-0.alpha}} are equal to {{1}}.
> I think this is likely due to a logical bug where any dot-separated segments
> following a zero or release ({{ga}} or {{final}}) is simply truncated in
> certain circumstances:
> {code:java}
> $ java -jar ~/local/apache-maven/lib/maven-artifact-3.6.3.jar 1-0.x 1-0
> Display parameters as parsed by Maven (in canonical form) and comparison
> result:
> 1. 1-0.x == 1-0.x
> 1-0.x == 1-0
> 2. 1-0 == 1
> {code}
> but
> {code:java}
> $ java -jar ~/local/apache-maven/lib/maven-artifact-3.6.3.jar 1-0.x-1 1-0-1
> Display parameters as parsed by Maven (in canonical form) and comparison
> result:
> 1. 1-0.x-1 == 1-0.x-1
> 1-0.x-1 > 1-0-1
> 2. 1-0-1 == 1-1
> {code}
