# ros2 launch vrx_gz competition.launch.py world:=sydney_regatta
[INFO] [launch]: All log files can be found below /root/.ros/log/2023-07-31-16-55-18-028318-130s-p16s-5941
[INFO] [launch]: Default logging verbosity is set to INFO
[ERROR] [launch]: Caught exception in launch (see debug for traceback): "package 'wamv_gazebo' not found, searching: ['/cws/install/vrx_gz', '/cws/install/vrx_ros', '/opt/ros/humble']"

Reproducing step

In Installing VRX, building only the pkgs in the defined dependency chain (i.e. in package.xml in each pkg) using the option of colcon build, --packages-above-and-dependencies vrx_gz (I admit the pkg passed to this option is decided rather arbitrarily though, passing only the absolutely needed pkgs to build process should be a reasonable need).

Env

$ cd %VRX% && git log -1
