Firmware 2.2.x compiling error (no replies)

Hi all,

I am trying to compile the Marlin firmware 2.2.x version.

I know about the Arduino IDE linking error related to long filenames, so I am using the Arduino CLI "Nightly" version.

Also running the Cmd.exe as administrator.

I am having the following compiling error: Anybody help help?

c:\users\moutinho\appdata\local\arduino15\packages\arduino\tools\avr-gcc\7.3.0-atmel3.6.1-arduino7\bin\../lib/gcc/avr/7.3.0/../../../../avr/bin/ar.exe: c:\temp\arduino-sketch-03B319767649EEEEAC127D5DB281EFB3\sketch\src\HAL\shared\backtrace\objs.a: Permission denied
