I have tried clean and reinstall different versions of maven with no luck. Any expert knows what is going on here?

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.

You just try to add this dependency in pom.xml of "APACHE Hadoop MR1". May ur error will resolve

Seems like Maven compiler plugin complaining that getDelegationTokenSecretManager() method in Hadoop FSNameSystem is not accessible due to method visibility i.e. it's not public:

[ERROR] /home/xiu/myGit/hadoop2/hadoop-mr1-project/hadoop-mr1/src/test/java/org/apache/hadoop/mapreduce/security/TestTokenCache.java:[153,4] getDelegationTokenSecretManager() is not public in org.apache.hadoop.hdfs.server.namenode.FSNamesystem; cannot be accessed from outside package
[INFO] 1 error

I would suggest you to check on your Hadoop version defined in your pom.xml, and double check that the method is really accessible in the Hadoop version JavaDoc.
