I am receiving errors (below) suggesting my CMakeLists.txt file does not properly define my launch folder, which contains .launch files, and my urdf and config folders within my src folder, which are used for various things.
No such file or directory: /snap/robot/x1/opt/ros/melodic/share/mapping/src/urdf/clearpath_jackal.urdf.xacro
RLException: while processing /snap/robot/x1/opt/ros/melodic/share/mapping/launch/robot_simulation.launch:
Invalid <param> tag: Cannot load command parameter [robot_description]: command [['/snap/robot/x1/opt/ros/melodic/lib/xacro/xacro', '/snap/robot/x1/opt/ros/melodic/share/mapping/src/urdf/clearpath_jackal.urdf.xacro', '--inorder']] returned with code [2].
Param xml is <param command="$(find xacro)/xacro $(find mapping)/src/urdf/clearpath_jackal.urdf.xacro --inorder" name="robot_description"/>
The traceback for the exception was written to the log file
Here's my CMakeLists.txt file:
cmake_minimum_required(VERSION 2.8.3)
project(mapping)
cmake_policy(SET CMP0054 OLD)
find_package(catkin REQUIRED COMPONENTS

DESTINATION ${CATKIN_PACKAGE_BIN_DESTINATION})
install(DIRECTORY launch/

Can anyone point out whats wrong?

opt/ros/melodic/share/mapping/src/urdf/clearpath_jackal.urdf.xacro seems like an odd path. Are you expecting your package to be installing that? I don't see anything in your CMakeLists.txt that indicates that you're installing any urdf files.

Yeah I'm still having trouble with that. What makes it look odd to you?
Comment by kyrofa on 2020-11-02:
Generally you don't see a src directory in an installed location.
Comment by Py on 2020-11-02:
I have various folders within my packages src folder to store files used by each node, e.g. config and simulation related files. Should these be located outside the src folder? Or are you saying that something needs to be done in CMakeLists.txt to better specify their location beyond the answer below?
