Description

AINSI colors are not working in newer maven versions, they do work with the maven version shipped with netbeans.

The solution is to add the following maven options

MAVEN_OPTS=-Djansi.passthrough=true

Maven 3.5.0 integrated jansi into its core. Jansi tries to detect the terminal capability and if it doesn't think that the terminal support ANSI codes, it strips them out of the output.

 

Testcase:

String greenBold = "\033[32;1m";
String reset = "\033[0m";
System.out.println("before" + greenBold + " green " + reset + "after");

1. If you run the above program against Maven 3.3.9, the word "green" will render using a green color inside the Netbeans output tab.
2. If you run the same program against Maven 3.5.0, no colors will show up.
