Description

Maven POMs have a <url> element, which is optional, but if not present Maven automatically calculates the URL using the parent project POM's URL and adding /${project.artifactId}.

The current Maven POMs in the Derby source only has a URL defined in the parent POM (./maven2/pom.xml), but not in the other POMs. So, for any module of the project, the generated URLs are invalid.

For, example, if you run the following in the ./maven2/client directory the URL is incorrect:

:~/projects/apache/svn/derby-code/maven2/client$ mvn help:effective-pom | grep '^  <url>'
  <url>http://db.apache.org/derby/derbyclient/</url>

This information is also used by the Maven Project Info Report plugin to generate the Dependencies report and the generated site causes 404 errors. For example, see http://www.deventropy.org/junit-helper/junit-helper-derby/dependencies.html#compile.

The attached patch adds the URL element to all the POMs.
