Problem verifying Marlin firmware for Mega 2560

The problem is that you have the Marlin sketch stored on your OneDrive. The most simple solution is to move it somewhere else on your computer.

For an explanation of the problem and workarounds to allow you to store it on your OneDrive see:

It seems recent Windows 10 versions combined with OneDrive suffer from arduino-b…uilder not being able to read files. This is reported as arduino/Arduino#6867 and arduino/Arduino#6932. The symptoms are similar as #90, but I think the underlying issue is similar but different, so I'm opening a new issue. arduino/Arduino#6932 contains the error output: ``` Arduino: 1.8.5 (Windows 10), Board: "Arduino/Genuino Uno" C:\Apps\arduino-latest\arduino-builder -dump-prefs -logger=machine -hardware C:\Apps\arduino-latest\hardware -hardware C:\Users\HaMac\AppData\Local\Arduino15\packages -hardware C:\Users\HaMac\OneDrive\Documents\Ardunio\hardware -tools C:\Apps\arduino-latest\tools-builder -tools C:\Apps\arduino-latest\hardware\tools\avr -tools C:\Users\HaMac\AppData\Local\Arduino15\packages -built-in-libraries C:\Apps\arduino-latest\libraries -libraries C:\Users\HaMac\OneDrive\Documents\Ardunio\libraries -fqbn=arduino:avr:uno -ide-version=10805 -build-path C:\Users\HaMac\AppData\Local\Temp\arduino_build_721501 -warnings=default -prefs=build.warn_data_percentage=75 -prefs=runtime.tools.arduinoOTA.path=C:\Users\HaMac\AppData\Local\Arduino15\packages\arduino\tools\arduinoOTA\1.1.1 -prefs=runtime.tools.avrdude.path=C:\Users\HaMac\AppData\Local\Arduino15\packages\arduino\tools\avrdude\6.3.0-arduino9 -prefs=runtime.tools.avr-gcc.path=C:\Users\HaMac\AppData\Local\Arduino15\packages\arduino\tools\avr-gcc\4.9.2-atmel3.5.4-arduino2 -verbose C:\Users\HaMac\OneDrive\Documents\Ardunio\BlinkTwoLEDs\BlinkTwoLEDs.ino readlink C:\Users\HaMac\OneDrive\Documents\Ardunio\BlinkTwoLEDs\BlinkTwoLEDs.ino: The system cannot find the file specified. Error compiling for board Arduino/Genuino Uno. ``` The reporter has tested a number of versions, and has found that 1.6.5 works, but 1.6.6 breaks things, on this particular system. The latter version is the one introducing arduino-builder. One difference here, is that the .ino file seems to be a link (or some other special file), not the directory. @phil85521 @ngmacha, could either of you get some more info on the .ino file that is failing? E.g. look at its properties or use some other Windows tool to figure out what kind of file it is, whether it is indeed a junction or some other kind of special file? I don't have any specific ideas what to do, not being a Windows-user. Looking at the go code previously patched (https://github.com/golang/go/commit/571738569e9b6bb30ebceaf2eb5936f6ee254e34#diff-495e6a9c70ec790e4be07ee30c55141f) it seems that this file might be (or have?) some kind of "reparse point" that is not a symlink or junction (which are the supported types). This [post](https://stackoverflow.com/questions/47264992/one-drive-as-reparse-point) suggests that OneDrive uses the "Cloud" reparse tag (`IO_REPARSE_TAG_CLOUD_7`), which golang does not seem to explicitly support (in its [master branch](https://github.com/golang/go/blob/master/src/syscall/syscall_windows.go#L1022-L1055)). I suspect this is something to fix at the golang end, it seems there is already a related issue open at https://github.com/golang/go/issues/22579 (which I'll provide with some extra info next).
