Thank you very much for all the details.
I am still a bit puzzled though...

So this works: System.out.println("Hello \u001b[31m red world!");
But this does not: mvn clean install -X
?

How do you run mvn clean install -X from inside Eclipse?

Anyway...

If the direct print works, and something like mvn (or any other external tool) does not, then the most likely problem is that the tool detects that the output is not a terminal and disables colors.

A lot of tools do that so that escape sequences don't end up in a file (if you do mvn install > somefile.log then you will see the same thing, the file does not contain any ansi escapes)

I don't know of any way to make the Eclipse console report that it is a tty.
So the only way is to force the tool to use colors even for for non-terminal output.
How to do that is tool dependent.

You can try this by running (in command line, not Eclipse):

mvn clean install > file.log
cat file.log

The log file does not contain colors.

Then try:

MAVEN_OPTS="-Djansi.passthrough=true"
mvn clean install > file.log
cat file.log

You should now see the maven colors.

I am still trying to figure out how to force that in Eclipse.

And would still help if you tell me how are you running mvn clean install -X from Eclipse.
Did you create a "Maven build" Run Configuration?

from ansi-econsole.

Did you create a "Maven build" Run Configuration?
Yes.
like this:
create a "Maven build" Run Configuration?
edit Goals "clean install -X" OR "clean install"

from ansi-econsole.

Did some digging (including reading through the sources for maven, jansi, and some of the maven Eclipse plugins :-)

It is not a problem with the plugin, it is the fact that the Eclipse does not report that it is a terminal (tty).
Because of that both maven and jansi don't output any color information.

And on top of that the "embedded" maven that comes with Eclipse uses the slf4j SimpleLogger, which does not even know about color at all, tty or not.

Here is a workaround, including some explanations at the end:

Thanks.
work well.

https://mihai-nita.net/2020/08/23/force-maven-colors-in-eclipse-console/
To force Maven to output color no matter the console type we need to set style.color=always.
To force Jansi to output color we need to set -Djansi.passthrough=true.
