Catkin_ws error: catkin_ws/src/package.xml does not exist

When trying to run catkin_make, I get the following errors:

CMake Error: File /home/user/catkin_ws/src/package.xml does not exist.
CMake Error at /opt/ros/kinetic/share/catkin/cmake/stamp.cmake:10 (configure_file):

It seems to be looking for the file catkin_ws/src/package.xml, which I donā€™t think is supposed to exist. Iā€™ve tried running catkin_make clean, but this is unable to run for the same reason. I also manually deleted catkin_make.cache and CMakeCache.txt before attempting a make, and this did not help.

Prior to this error occurring, I accidentally created a package directly under catkin_ws, then attempted to move it by running ā€œmv package_name/* src/ā€ , but then I decided to just remove all of those files from the src/ directory and run the command again. I think the error is caused by some remnant from this process somewhere. Any way I can clean this up?

Edit: Iā€™ve tried exiting the workspace for more than 20 minutes (overnight), as it has been stated in other threads that this causes a new virtual computer assignment, which did not work. I ended up trying to download the build and devel folders from the workspace of another lesson path and replacing the existing folders in the ROS Basics in 5 Days learning path. However, the files seem to actually be broken across all of the learning paths and replacing them did not work.

One thing I thought might be significant-- in the catkin_ws/build/catkin_generated/stamps directory, the generated subdirectory is always called ā€œactions_quizā€ rather than ā€œProjectā€ after attempting catkin_make.

I found a solution:

I created a backup of my packages, and just deleted the entire catkin_ws directory and rebuilt it. From the ~/user directory:

rm -r catkin_ws
mkdir -p catkin_ws/src
cd catkin_ws
catkin_make

The first compile takes awhile, but the problem is fixed finally.
