How to install rosjava on ROS Groovy?

edit

I try to enter the following instructions

mkdir -p ~/code/rosjava
wstool init -j4 ~/code/rosjava/src https://raw.github.com/rosjava/rosjava/hydro/rosjava.rosinstall
cd ~/code/rosjava
rosdep update
rosdep install --from-paths src -i -y
catkin_make

When I run rosdep install, it shows the error that rosjava_messages: Cannot locate rosdep definition for [segbot_sensors]:

sam@sam:~/code/rosjava$ rosdep install --from-paths src -i -y
WARNING: Package name "swig-wx" does not follow the naming conventions. It should start with a lower case letter and only contain lower case letters, digits and underscores.
ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
rosjava_messages: Cannot locate rosdep definition for [segbot_sensors]
sam@sam:~/code/rosjava$

When I rosmake, it shows the error that Could not GET 'https://github.com/rosjava/rosjava_mvn_repo/raw/master/org/apache/commons/com.springsource.org.apache.commons.codec/1.3.0/com.springsource.org.apache.commons.codec-1.3.0.jar:
