Thanks Wayne. I tried that but no luck! The tutorial does not specify where to put c:/dev/sandboxes/maven/sample-mojo/maven-hello-plugin/src/main/java/sample/p lugin/GreetingMojo.java. I suspect I don't have this in the correct directory. Since I did the steps out of order, I already had a src/main/java/sample/plugin directory which looked like a logical place to put GreetingMojo.java. Where is the pom.xml in the tutorial looking for GreetingMojo.java?
