It does work with 3.6.3 already. Can someone else confirm?

> jansi messes up System.err and System.out
> -----------------------------------------
>
> Key: MNG-6239
> URL: https://issues.apache.org/jira/browse/MNG-6239
> Project: Maven
> Issue Type: Bug
> Components: core
> Affects Versions: 3.5.0
> Environment: Java 1.8.0_131, Ubuntu 17.04
> Reporter: Simone Bordet
> Priority: Minor
> Attachments: mvn-jansi.tgz
>
>
> I use the Maven Exec Plugin to run a class that asks for interactive input
> from the user. This was working in 3.3.9, but does not work in 3.5.0.
> Anything printed on {{System.err}} or {{System.out}} without a newline is not
> printed immediately on the terminal window.
> Example:
> {code:java}
> BufferedReader console = new BufferedReader(new InputStreamReader(System.in));
> System.err.printf("listen port: ");
> String value = console.readLine().trim();
> {code}
> The example above would not print {{listen port:}} on the terminal.
> Attached you can find a project that reproduces this issue.
> Unpack the project and then run:
> {noformat}
> $ mvn install && mvn exec:exec
> {noformat}
> The expected output of the reproducer would be:
> {noformat}
> err.println
> out.println
> err.printerr.printfout.printout.printf
> {noformat}
> instead I get:
> {noformat}
> err.println
> out.println
> {noformat}
> Removing {{jansi-1.13.jar}} from {{$MAVEN/lib/}} fixes the issue.
