I'm actually surprised no one has commented on this. While I can see
the benefits it might also be confusing when you realize that
mvn://org.springframework/spring-beans/2.5.6
is equivalent to
http://myrepsoitory/org/springframework/spring-beans/2.5.6/spring-beans-2.5.6.jar

One of the things that's always gnawed at me is the three separate
attributes needed to define a dependency. Really, there is an implied
constraint here as they relate in a hierarchical manner, but jointly
define
one thing. There happens to be another problem domain that has
solved the
idea of identifying resources universally using a single identifier,
namely
the internet. So here's an idea: name dependencies by URIs under a
mvn:
scheme.
What if...
mvn://${groupID}/${artifactId}/${version}
meant the obvious thing. What if the following were equivalent:
Maven 2:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>2.5.6</version>
</dependency>
Proposed Maven 3:
<dependency uri="mvn://org.springframework/spring-beans/2.5.6"/>
Similarly for archetyptes, these would be equivalent:
Maven 2:
mvn archetype:generate \
-DgroupId=org.sonatype.mavenbook \
-DartifactId=quickstart \
-Dversion=1.0-SNAPSHOT \
-DpackageName=org.sonatype.mavenbook \
-DarchetypeGroupId=org.apache.maven.archetypes \
-DarchetypeArtifactId=maven-archetype-quickstart \
-DarchetypeVersion=1.0
Proposed Maven 3:
mvn archetype:generate \
-Duri=mvn://sonatype.mavenbook/quickstart/1.0-SNAPSHOT \
-DarchetypeUri=mvn://org.apache.maven.archetypes/maven-archetype-
quickstart/1.0
\
-DpackageName=org.sonatype.mavenbook
Thoughts?
