I came across same problem during hadoop 2.2.0 source code building. During "mvn install -DskipTests" this error came in "Hadoop Auth" Folder. From somewhere(i dont remember from where) i came to know that there is one missing dependency in pom.xml of this Hadoop Auth folder

dependency is

<dependency>
  <groupId>org.mortbay.jetty</groupId>
  <artifactId>jetty-util</artifactId>
  <scope>test</scope>
</dependency>

I added this dependency and again tried "mvn install -DskipTests". My error resolved. Hope this will work in your case also

Apache documentation says 'JavaTM 1.6.x, preferably from Sun, must be installed.'.

Also, check the override behavior in the different versions of Java.

Looks like you have Java 5.
