Invalid URL in effective POM of project

[bindul]

The project's POM does not define a <url> and based on how the parent POM defines a URL: http://www.mojohaus.org/${project.artifactId}, the generated URL on this project is a non-existent page.

$ mvn help:effective-pom | grep -v "^\[INFO\]" | grep -v "^Effective POMs" | grep -v "^$" | xpath -q -e "//project/url/text()"
http://www.mojohaus.org/buildnumber-maven-plugin/buildnumber-maven-plugin

While the correct URL should be: http://www.mojohaus.org/buildnumber-maven-plugin/

While this in itself is not an issue with the functioning of the project; the Maven project-info-report plugin uses the effective URL in the Project Plugin Management report. This of course causes a 404 error.
