["Tom Wieczorek (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MNG-6220?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16243779#comment-16243779 ] 

Tom Wieczorek commented on MNG-6220:
------------------------------------

I'm somehow not able to see any change when using {{-Dstyle.color=XXX}} with Maven 3.5.2. It always uses the auto detection. Can somebody confirm that it's working? I tried {{never}} at the terminal and had colors. I tried {{always}} when piping, and got no colors. I also tried some bogus value to trigger the exception, but to no avail.

I tried both {{MAVEN_OPTS}} and as an argument to {{mvn}}.

> Currently, the only way to enable/disable color output is to use the batch-mode or log-file options.
> If a user wants colored output but no interactivity (ie: jenkins environment with the ansicolor plugin), there is no CLI option combination to support the use-case.
> I propose to add an option to control output coloring directly.
> {noformat}
> --color=enabled <- color output always enabled
> --color=disabled <- color output always disabled
> --color=auto <- current behavior (default)
