Hi, I'm following the http://www.ros.org/wiki/rosjava/Build tutorial using ros electric from the ubuntu repository and rosjava from mercurial. In the manifest.xml, I wrote In the generated .classpath file, I get: However, in the ~/.ros/rosjava/lib, I have a sensor_msgs.jar file, and no org.ros.rosjava.sensor_msgs-0.0.0.jar. I have a similar issue with topic_tools and geometry_msgs even though I did not add them to the manifest.xml file.
