Description

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:

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:
