What version of the product are you using? On what operating system?
Ubuntu 12.04, ROS Hydro

Please provide any additional information below.
I've successfully updated all other dependencies in april_tag_node's 
build.gradle file (see attached). I can't seem to figure out where the 
dependency for april_msgs is missing, however. The april_msgs folder is at the 
same level as the april_tags_node folder. All other packages seem to be 
installed just fine.

I'm afraid this package is no longer maintained. I haven't kept up with ROS 
java since I originally ported over the april code for ROS Fuerte, and I'm not 
exactly sure how difficult it is to get this package to work in Hydro.

Here are a few suggestions to continue:
1) Contact the ROS Java Interest group at ros-sig-java@googlegroups.com and see 
if someone can help you port the code from Fuerte to Hydro.
2) If you don't care about which tracker you're using, you can use 
http://wiki.ros.org/ar_track_alvar
3) Wrap the new release of the C++ April Library using roscpp
