Catkin_Make Android_Core Error in Hydro

edit

I'm following the tutorial at

http://wiki.ros.org/sig/Rosjava/Android%20Development%20Environment/hydro

to set up my Android Workspace. I'm following the steps and I built rosjava. The very last step of doing 'catkin_make' to the android workspace results in this error

where is this 'maven' file?
