-------------------------------------

I would prefer URNs here as a URI.

>                 Key: MNG-7039
>                 URL: https://issues.apache.org/jira/browse/MNG-7039
>             Project: Maven
>          Issue Type: Improvement
>            Reporter: Matt Pavlovich
>            Priority: Major
>
> Provide the ability to reference maven artifacts using a uri-like syntax 
> reduces verbosity.
> Reasoning:
> 1. The XML elements for groupId, artifactId, version, classifier and type are 
> never extended
> 2. Reducing lines of text improves maintenance of pom's
> 3. URI is a first-class citizen in XML schema and can be strongly typed, and 
> regex'd.
> 4. Maven GAV(CT) as a uri makes sense, since they are both coordinates of 
> sorts.
> Challenges:
> 1. Requires the uri to be parsed for variable substitution (esp version)
> Option 1-- classifier and type as query params (probably more useful):
> {noformat}
> Given:
> <dependency>
>   <groupId>com.company</groupId>
>   <artifactId>foo-api</artifactId>
>   <version>1.0.1-SNAPSHOT</version>
>   <classifier>default</classifier>
>   <type>jar</jar>
> </dependency>
> Maven 4.x feature:
> <dependency 
> uri="mvn://com.company/foo-api/1.0.1-SNAPSHOT?classifier=default&amp;type=jar"
>  scope="compile"/>
> w/ properties:
> <dependency 
> uri="mvn://com.company/foo-api/${project.version}?classifier=default&amp;type=jar"
>  scope="compile"/>
> {noformat}
> Option 2-- classifier and type as path params:
> {noformat}
> <dependency uri="mvn://com.company/foo-api/1.0.1-SNAPSHOT/default/jar" 
> scope="compile"/>
> {noformat}
