Resource not found

Hi Every one,
I'm a newbie on ROS and Gazebo and for my student project, I'm using ROS Melodic and I'm trying to use this tutorial : ainstein_radar_gazebo_plugins. I can compile with no error but when I want to launch, this is the error :
Resource not found: The following package was not found in <arg name="world_name" value="$(find gazebo_radar_sensor_plugin)/worlds/test.world"/>: gazebo_radar_sensor_plugin
ROS path [0]=/opt/ros/melodic/share/ros
ROS path [1]=/home/thomaspc/catkin_ws/src
ROS path [2]=/opt/ros/melodic/share
The traceback for the exception was written to the log file

In the tutorial, they say I have to fill the bashrc with this :
export GAZEBO_MODEL_PATH=$GAZEBO_MODEL_PATH:~/.gazebo/models
and this : export GAZEBO_PLUGIN_PATH=$GAZEBO_PLUGIN_PATH:~/catkin_ws/devel/lib
I don't understand my mistake and even after some research
Could you hepl me please
Thank you !
