https://github.com/EuropeanRoverChall... Using the link I wrote all commands which is given in "Install on the host system" section.

When I try this command:

$ roslaunch ur3_sim simulation.launch

It gives error like this:

The --inorder warning message in the title to this question is not the actual problem here.

The error "No such file" indicates that your UR3_sim/ur3_sim_description/urdf/ur3_sim.urdf.xacro file is not compatible with the newest universal_robot ros package. You need to fix the file paths inside that file.
