You should add it to the plugin's dependencies.
Here is an example extract from one of my POMs (the irrelevant bits removed):
<plugin>
.....
<dependencies>
<dependency>
<groupId>org.apache.maven.surefire</groupId>
<artifactId>surefire-api</artifactId>
<version>2.4.3</version>
</dependency>
</dependencies>
</plugin>
