Console output defaults to plain on Linux starting with Gradle 8.12

[britter]

Current Behavior

When running a build with Gradle 8.12 on Linux the console output type is plain by default. Only if specifying --console=rich the output is rendered using the rich console.

Expected Behavior

When running a build without specifying the console output type it should default to the rich console output.

Fwiw, I don't have that problem on my side ("works on my machine")

Color output works fine here, too, with Gradle 8.12 on Fedora Linux 41 (KDE spin, Konsole application).

What's your TERM environment variable, @britter?

[britter]

@sschuberth my TERM variable is either alacritty or tmux-256color depending on whether I'm in a tmux session. Is doesn't work for either TERM variable setting on Gradle 8.12.

[sschuberth]

I tried both like TERM=alacritty ./gradlew tasks and I do get colored output. My regular TERM value is tmux-256color as well.

Given that others cannot reproduce, we need more information to understand what's causing this. Getting NixOS setup is not something we can do right now.

[britter]

I tried to get to the bottom of this but had no luck analyzing the issue. I tried running builds with ./gradlew tasks --no-daemon -Dorg.gradle.debug=true and then set break point in different places.

First I set a break point in DefaultLoggingConfiguration#setConsoleOutput to see whether that is initialized the wrong way, but it's initialized with Auto.

Then I tried to figure out how Auto is process by setting a break point in ConsoleConfigureAction#execute but it never stopped there.

I tried setting a break point in the initialization of the AnsiConsole but again it never stopped there.

I don't understand why it never hits the relevant break points, so right now I don't know how to continue.

This is a NixOS specific problem that is related to patching native libraries, see NixOS/nixpkgs#356109 (comment). It will be fixed once that PR is merged.
