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

Benjamin, could this also be expanded for plugin versions?

>             Project: Maven 2
>          Issue Type: Bug
>          Components: Dependencies
>    Affects Versions: 2.2.1, 3.0-alpha-2
>            Reporter: Paul Benedict
>            Assignee: Benjamin Bentmann
>             Fix For: 3.0-alpha-3

> I declared a dependency as such:
> {noformat}<dependency>
>     <groupId>org.slf4j</groupId>
>     <artifactId>slf4j-api</artifactId>
>     <version>${slf4j.version}</version>
> </dependency>{noformat} 
> But did not define the *slf4j.version* property. Obviously ${...} is an expression and if the expression is not resolved, why allow it? Here was the output:
> {noformat} Downloading: http://repo1.maven.org/maven2/org/slf4j/slf4j-api/${slf4j.version}/slf4j-api-${slf4j.version}.pom{noformat} 
> In terms of usability, an obvious expression should be interpolated. If it cannot, it should be a runtime error.
