Parent sketch directory not recognized when given relative path. Workaround.

Path "/home/user/sketch/sketch.ino" is accepted. Path "./sketch.ino" results in an error, as the sketch is not recognized to reside in parent directory "sketch".

Translating all paths to absolute does work, as demonstrated by the linked script.

https://github.com/mirage335/arduinoUbiquitous/blob/master/_prog/core.sh#L109

Start by reproducing the difference between the absolute path "/home/user/sketch/sketch.ino" and the relative path "./sketch.ino", then inspect the sketch path handling in the Arduino IDE. Compare the behavior with the linked core.sh workaround; done means a relative sketch path is recognized in its parent directory without requiring path translation.
