How to attend to WARN ‘Unable come instantiate org.fusesource.jansi.WindowsAnsiOutputStream’ inlog4j2


Our job use log4j2 as log library.Sometimes us build and also run unit check at local(Windows OS) and seems slow-moving down by miscellaneous relate come library.

You are watching: Warn unable to instantiate org fusesource jansi windowsansioutputstream



The trouble is just like this thread

Seems log4j2 usage jansi for vivid printing on home windows by default.We didn’t incorporate this library and thus cause the hold-up for looking the class.

Quick solution is disable

System.setProperty(“log4j.skipJansi”, “true”)

Wondered if there is any method we might setup this sort of device problem
