I am getting a compile error when trying to use a dependency on baxter mesages. Any idea on what I am missing?

I have run this

genjavamessageartifacts --verbose -p baxtercoremsgs

so have this

./devel/share/maven/org/ros/rosjavamessages/baxtercoremsgs/1.2.0/baxtercore_msgs-1.2.0.jar

and in build.gradle have included the dependency,

dependencies { compile 'org.ros.rosjavacore:rosjava:[0.2,0.3)' compile 'org.ros.rosjavamessages:baxtercoremsgs:1.2+' }

In packages.xml I have included

baxtercoremsgs

Here's the error

Could not resolve all dependencies for configuration ':rosjavabaxterproject:compile'. Could not find any version that matches org.ros.rosjavamessages:baxtercoremsgs:1.2+.
