Package not found when trying to launch a simulator (Gazebo)

[aquasphere0904]

Hi,

I have built the ROS 2 workspace environment as follows:

source /opt/ros/jazzy/setup.bash
mkdir -p ~/ros2_ws/src
cd ~/ros2_ws/src
git clone https://github.com/jsk-enshu/robot-programming.git
cd ~/ros2_ws
vcs import src < src/robot-programming/.repos.jazzy
sudo apt update
rosdep update
rosdep install --from-paths src --ignore-src -y
colcon build --symlink-install
export ROS_AUTOMATIC_DISCOVERY_RANGE=LOCALHOST
sudo apt install ros-jazzy-nav2-route

Then, I tried to launch the dynamics simulator (Gazebo) with the following commands,
but encountered a “Package not found” error:

source ~/ros2_ws/install/setup.bash
ros2 launch jedy_bringup jedy_gazebo.launch.py

Error message:

Package 'jedy_bringup' not found: "package 'jedy_bringup' not found, searching: ['/home/USER_NAME/ros2_ws/install/opencv_apps', '/opt/ros/jazzy']"

However, the package does exist in my workspace:

find . -name *jedy_bringup*
./src/robot-programming/jedy/jedy_bringup

find . -name jedy_gazebo.launch.py
./src/robot-programming/jedy/jedy_bringup/launch/jedy_gazebo.launch.py

Could you please tell me how to resolve this issue?

Thank you in advance!

None of this relates to Nav2, closing as off topic. jedy_bringup nor https://github.com/jsk-enshu/robot-programming.git are related to Nav2. Please ask that author for support.

Hello @SteveMacenski,
I was able to resolve the issue by moving the jedy folder directly into the src directory and specifying both jedy_bringup and jedy_description in the colcon build command:

$ cd ~/ros2_ws/src
$ mv robot-programming/jedy/* .
$ colcon build --symlink-install --base-paths src/jedy_bringup src/jedy_description

Thank you for your assistance!
