To use the plugin you have to add it in the plugin-section in your pom.xml file of your project.
Here is an example (make sure you define the latest release).
<pom>
...
...
...
<build>
<finalName>simple</finalName>
<plugins>
<plugin>
<groupId>com.googlecode.t7mp</groupId>
<artifactId>maven-t7-plugin</artifactId>
<version>0.9.10.M8</version>
</plugin>
...
more plugins
...
</plugins>
</build>
...
...
</pom>To run the Tomcat-Instance you can use the following command (install is to package your project, if you did not yet).
mvn clean install t7:run
