Karl Heinz Marbaise commented on MNG-6232:
------------------------------------------
The simple answer to this is: {{1.8.0-alpha-2}} is less than {{1.8}} which
fulfils the requirement of the given range {{[1.7,1.8)}}. A little more in
detail.
The version range {{[1.7,1.8)}} just means greater or equal {{1.7}} and
less than {{1.8}}. By definition {{1.8-alpha-2}} is less than {{1.8}} which
means in consequence less than {{1.8}} which will fulfil the requirement. This
can be checked by using
{code}
java -jar apache-maven-3.3.3/lib/maven-artifact-3.3.3.jar 1.8 1.8-alpha-2
{code}
(Works with newer Maven versions as well).
This will printout:
{code}
Display parameters as parsed by Maven (in canonical form) and comparison result:
1. 1.8 == 1.8
1.8 > 1.8-alpha-2
2. 1.8-alpha-2 == 1.8-alpha-2

> Project: Maven
> Issue Type: Bug
> Components: Dependencies
> Affects Versions: 3.3.3
> Reporter: Marek Budyn
> Attachments: pom.xml

>
> When dependency is specified as range, e.g slf4j-api version [1.7, 1.8) as in
> provided pom.xml, one would expect to resolver to version 1.7.X (e.g.
> 1.7.25). Instead maven resolves version 1.8.0-alpha 2.
> Output of command 'mvn dependenct:tree' on provided pom.xml:
