Maven plugin not executing even though it is bound to a build phase

I am new to maven, and am having trouble executing a plugin. Currently I have bound it to the package phase, but when I do mvn clean package, or mvn clean install, it is not being executed. However, when I call the plugin by name, it executes as it should. What have I misunderstood/what is wrong with my code?

                 <configuration>
                    <target name="UploadAndScan" description="Turns on debug symbols, logging. Cleans, builds, uploads binaries. Starts scan">
                       <!-- Call the Veracode wrapper to upload and scan -->

           </executions>

This is the code that defines the plugin, located in the top-level pom.

Did you, by accident, put the plugin into <pluginManagement>?

Then it will not be executed and you need to move it to <plugins>.
