Multiple progress bars end up on a single line under osx with 0.9.4

[spinscale]

I am creating multiple progress bars, each one as a task in a thread pool (up to 300). When. the thread pool is running more than one task at once, the progress bars all end up on the same line.

I checked an Terminal.cursorMovementSupported is set to true.

The code looks like this:

executorService.submit(() -> {
    try (CliProgressMonitor progressMonitor = new CliProgressMonitor(message, terminalWidth.get())) {
        // do long running task
    }
});


private static final class CliProgressMonitor extends BatchingProgressMonitor implements AutoCloseable {

    private final ProgressBar progressBar;

    public CliProgressMonitor(String message, int terminalWidth) {
        this.progressBar = new ProgressBarBuilder()
            .setStyle(ProgressBarStyle.UNICODE_BLOCK)
            .setTaskName(message)
            .setMaxRenderedLength(terminalWidth)
            .hideETA()
            .build();
    }

    ...
}

Is there anything wrong with the approach, should the closing of the progressbar be changed or sth?

Thanks for your help!

Which environment are you running in? e.g. Linux terminal, or Windows WSL, or in a Docker container?

[spinscale]

Under osx, I tried with iterm2 as well as wezTerm. This is what it looks like..

So, every "Fetching repo..." is an own progressbar (that is the message), and if you look closely, the last line flips between the 10 concurrent running progresses and only creates a newline once the progress is finished.

oh!that's my fault，I have omitted some irrelevant code，The correct content is this out.print(str);
