Question: I saw that there is a very nice python library ([PyBBIO](https://github.com/alexanderhiam/PyBBIO)) for direct Control of the BBB using mmap on /dev/mem/ (granted not for the muxing). With some goodies like Webmonitor etc. Unfortunatly this library is not running on the 3.8 Kernel.

Are there any viable alternatives in python/c/c++ using mmap? I saw some but non was as complete as the mentioned PyBBIO.

I did successfully try the solution explained [here](https://stackoverflow.com/questions/13124271/driving-beaglebone-gpio-through-dev-mem). But implementing everything (UART/PWM) sounds like it would be something to difficult for me to do...

Answer: 
I had the same problem after deploying jenkins war; all I had to do was to restart the server after the deploy.
Hope it helps.
I had the same problem, after deleting all `.jar` files and build the path to all `.jar` file once again. Now it's working properly
