Unable to customize Dependencies version ordering while using range in
dependency version tag
----------------------------------------------------------------------------------------------
Key: MNG-5066
URL: http://jira.codehaus.org/browse/MNG-5066
Project: Maven 2 & 3
Issue Type: Improvement
Components: Artifacts and Repositories, Dependencies
Affects Versions: 2.2.1
Reporter: Aziz Joumady
Priority: Minor
Hi all,
Currently, Maven fails to properly resolve dependencies while version follow
this pattern :
[0-9][0-9]*\.[0-9][0-9]*\.[0-9][0-9]*-[alpha|beta|rc]-[0-9][0-9]*
e.g.
1.0.0-alpha-2
1.0.0-alpha-10
1.0.0-beta-3
etc.
As described in following link
http://www.sonatype.com/books/maven-book/reference/pom-relationships-sect-pom-syntax.html

One gotcha for release version numbers is the ordering of the qualifiers. Take
the version release numbers "1.2.3-alpha-2" and "1.2.3-alpha-10", where the
"alpha-2" build corresponds to the 2nd alpha build, and the "alpha-10" build
corresponds to the 10th alpha build. Even though "alpha-10" should be
considered more recent than "alpha-2", Maven is going to sort "alpha-10" before
"alpha-2" due to a known issue in the way Maven handles version numbers.
Maven is supposed to treat the number after the qualifier as a build number. In
other words, the qualifier should be "alpha", and the build number should be 2.
Even though Maven has been designed to separate the build number from the
qualifier, this parsing is currently broken. As a result, "alpha-2" and
"alpha-10" are compared using a String comparison, and "alpha-10" comes before
"alpha-2" alphabetically. To get around this limitation, you will need to
left-pad your qualified build numbers. If you use "alpha-02" and "alpha-10"
this problem will go away, and it will continue to work once Maven properly
parses the version build number.

Is it possible to add a new feature enabling to customize the way Maven
compares version resolution?
Adding for example a regular expression pattern.
Kind regards,
Aziz
