      With a standard Maven job, I'm not getting ANSI color output from Maven in the console output (Web UI) despite calling Maven with -Dstyle.color=always and having MAVEN_OPTS with -Djansi.force=true. This is with Maven 3.5.4 and 3.6.3, I do get color output when switching to old Maven 3.0.4, which unconditionally outputs some ANSI sequences.

      I'm at a loss what to try further and what could be the cause of the problem.

      Example console ouput from a build, not showing any color:

      Modules changed, recalculating dependency graph

      Note that the following does output color, so the problem is really with Maven's own output not generating color:

                                      print("\u001b[1;31mBold Red\u001b[0m");
