For better support by building tools. As reported by @KnustJohn_twitter , the custom [@phase](https://maven.apache.org/plugin-tools/maven-plugin-tools-java/index.html) Javadoc tag made NetBeans fail on Javadoc generation for the GitRevmavenTask class. Using instead standard Java 5 [annotations](https://maven.apache.org/plugin-tools/maven-plugin-plugin/examples/using-annotations.html#POM_configuration) this is no more an issue.
