Processing project started in CMD - error handling

Hmmm, good, but, when i will have some Syntax error it doesnt show it…

It works well, but, why it cant save to “error-chech.log” file ? … the output of CMD console

cd C:\Users\ASROCK\Documents\processing-3.3.6\
start cmd.exe @cmd /k "@echo off&color 0a&processing-java --sketch=C:\Users\ASROCK\Desktop\loader\output_files\main --output=C:\Users\ASROCK\Desktop\loader\output_files\main\output-compile --force --run > C:\Users\ASROCK\Desktop\loader\error-check.log"
exit

The output of the CMD console, it creates log file, but it doesnt save the console lines…
