Hi,
I am having trouble building custom ROS msgs and adding them to availabe msg definitions in MATLAB.
I followed this tutorial – https://se.mathworks.com/help/ros/ug/create-custom-messages-from-ros-package.html
I am getting the follwing error.
Building custom message files for the following packages: carla_common carla_msgs carla_ros_bridge :rosjava_messages is spawning subprojects: [carla_common, carla_msgs, carla_ros_bridge]Creating properties on demand (a.k.a. dynamic properties) has been deprecated and is scheduled to be removed in Gradle 2.0.

Run with --info or --debug option to get more log output.BUILD FAILEDTotal time: 2.958 secsAn error occurred while building custom messages. See the full error message above.Possible reasons for the error:1. The msg or srv files may have syntax errors.2. The dependencies on other message packages may not be declared correctly in the build_depends tags in the package.xml.3. Messages packages declared as dependencies may not be available.4. The custom message packages may be missing a build dependency on "message_generation".See the ROS Custom Messages documentation for more information.I figured that the geometry_msgs available in MATLAB are old and don't contain new definitons, therefore I built the geometry_msgs alone forst and added it to the MATLAB. I am able to see them in the rosmsg list
