"Generate Code" deletes 6 source files from an imported example (Nx_MQTT_Client) from ST's set. Manually replacing files temporarily fixes (until the next "Project->Generate Code".

[AShap.3]

I've a bunch of issues with STM32CubeIDE.

To repeat the "Deleted Source Files" issue in STM32CubeIDE, running on a Mac M2 or Intel (not a Rosetta issue) under MacOS Ventura 13.x. STM32U5 board. Do the following:

File->Import... General:Import STM32Cube Example

Name: Nx_MQTT_Client

Pick Name=Nx_MQTT_Client / Board=B-U5851-IOT02A

Hit "Next" and create the new project by following the prompts.

Do a Project->Build Project (which should succeed even if WiFi info not supplied as per readme).

Since I know what's going to happen next, copy the following files from the newly installed project, perhaps using the following terminal command:

cp ~/STM32CubeIDE/workspace_1.11.0/Nx_MQTT_Client/Middlewares/ST/netxduo/common/src/{nx_ram_network_driver.c,nx_tcp_server_socket_driver_listen.c,nx_tcp_socket_driver_establish.c,nx_tcp_socket_driver_establish.c,nx_tcp_socket_driver_packet_receive.c,nx_udp_socket_driver_packet_receive.c} /tmp

(that's all on one line BTW).

Then do a "Project->Generate Code", followed by a "Project->Build Project". On my setup, the files I copied out to /tmp are now all missing and the "Build Project" fails. The command:

cp /tmp/{nx_ram_network_driver.c,nx_tcp_server_socket_driver_listen.c,nx_tcp_socket_driver_establish.c,nx_tcp_socket_driver_establish.c,nx_tcp_socket_driver_packet_receive.c,nx_udp_socket_driver_packet_receive.c} ~/STM32CubeIDE/workspace_1.11.0/Nx_MQTT_Client/Middlewares/ST/netxduo/common/src

restored the missing files and subsequent "Project->Build Project" succeed until the next "Project->Generate Code".

Any ideas what is causing the file deletion issue?

Thanks for picking this up. There was a spurious space in each of the shell commands (above). I fixed them.

(No... that does not fix the problem... it fixes my work-around report - which is UNIX specific)

Try to uncheck in the Cube "delete previously generated files when not re-generated"

Thanks for trying but... same problem :(
