adding "output": "/ArduinoOutput" to arduino.josn fails the build with

Please see the build logs in output path: d:\TEST\ArduinoOutput
The system cannot find the file specified.
Error during build: exit status 1
[Warning] Failed to generate IntelliSense configuration.
[Error] Uploading sketch '00_Code\ESP_Test\ESP_Test.ino': Exit with code=1

is this caused by the file and projekt beeing on the D: and not C: drive ??
