tomcat7-maven-plugin extraDependency not working with class not found
---------------------------------------------------------------------

                 Key: MTOMCAT-106
                 URL: https://issues.apache.org/jira/browse/MTOMCAT-106
             Project: Apache Tomcat Maven Plugin
          Issue Type: Bug
          Components: tomcat7
    Affects Versions: 2.0
         Environment: Ubuntu 11.04 @32bit with Maven 2.2.1 and Java 1.6.0_26
            Reporter: William Ghelfi
            Assignee: Olivier Lamy


Hello,

I'm trying to use the 'exec-war-only' goal from version 2.0-SNAPSHOT of tomcat7-maven-plugin,
taken from 
http://people.apache.org/repo/m2-snapshot-repository

Needing derby, I would use the extraDependencies configuration element as showed in the second
example at:
http://tomcat.apache.org/maven-plugin-2.0-SNAPSHOT/executable-war-jar.html

Here's my configuration:

<plugin>
	<groupId>org.apache.tomcat.maven</groupId>
	<artifactId>tomcat7-maven-plugin</artifactId>
	<version>2.0-SNAPSHOT</version>
	<executions>
		<execution>
			<id>tomcat-run</id>
				<goals>
					<goal>exec-war-only</goal>
				</goals>
				<phase>package</phase>
				<configuration>
					<path>/${project.artifactId}</path>
					<enableNaming>true</enableNaming>
					<extraDependencies>
						<extraDependency>
							<groupId>org.apache.derby</groupId>
							<artifactId>derby</artifactId>
							<version>10.8.2.2</version>
						</extraDependency>
					</extraDependencies>
				</configuration>
		</execution>
	</executions>
</plugin>


So I launch "mvn clean package -e" and get:

org.apache.maven.lifecycle.LifecycleExecutionException: Error configuring: org.apache.tomcat.maven:tomcat7-maven-plugin.

Then I tried to get sources and build myself a plugin newer-than-the-latest-snapshot, but
it failed on execution just as the snapshot

So, I forked the mirror you have on github and hacked a patch that just works for me and follows
the syntax found for another similar snippet (<warRunDependencies>)
This is because I'm a power linux user and mid-level web designer, rather than a Java programmer,
so I didn't manage to follow a different way to get it work :)

Here is the pull request with the patch:
