org.codehaus.plexus.util.Scanner がない問題の解決

Maven でこんなのが出たら・・

[INFO] Internal error in the plugin manager executing goal 'com.mysema.maven:apt-maven-plugin:1.0.4:process': Unable to load the mojo 'com.mysema.maven:apt-maven-plugin:1.0.4:process' in the plugin 'com.mysema.maven:apt-maven-plugin'. A required class is missing: org/codehaus/plexus/util/Scanner
org.codehaus.plexus.util.Scanner

Maven 2.x ではなく Maven 3 を使うと解決します。
