"No runnable methods" when using Maven for a class that shouldn't be Tested

I recently ran into a problem doing a Maven build where I had a utility class to be used for my Test cases. Adding the @Ignore tag didn't seem to help. It turns out the solution was simply to add this plugin entry to my pom.xml file as my file had the suffix Util.java:

<plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-surefire-plugin</artifactId>
   <configuration>
      <excludes>
         <exclude>**/*Util.java</exclude>
      </excludes>
   </configuration>
</plugin>
