Hi, I'm trying to follow the instructions on http://www.ros.org/wiki/rosjava/Build. I installed ros electric and rosjava-core using the ros Ubuntu repository. In the wiki page (http://www.ros.org/wiki/rosjava/Build), step 3 "Building your ROS package", I get a $ rosmake myproject ... BUILD FAILED /home/cassou/Documents/robotics/stacks/diarobot/build.xml:20: ros.properties is missing. Please type 'rosmake' first I can confirm the file ros.properties exists. However, the build.xml file contains the line: I think this is the line which fails because the ros.properties file does not define ros.compile.classpath. The file defines a lot of other variables though (such as ros.classpath). Can you please help me?
