Bug: npx tailwindcss with args --watch

Description

Hi, I tried to execute the following task (go to reproduce the error for more details) and the problem is when I added --watch in args, when I add this command, it did not work, I don´t know why does this happens, Is there a bug when I execute some command with --watch like ng server --watch or similar? I tried to, execute Spring boot application and execute tailwind in parallel because I used thymeleaf.

Note: I clarify that the command does work if I remove the --watch, but I want the file to be pending changes

Reproduce error

     1 -- I made a task in build.gradle

tasks.register('frontend', NpxTask) {
    command = 'tailwindcss'
    ignoreExitValue = true

    inputs.files('package.json', 'package-lock.json', 'tailwind.config.js', 'postcss.config.js')
    inputs.files(fileTree('./src/main/resources/static'))
    inputs.files(fileTree('./src/main/resources/templates'))

    outputs.dir('./build/resources')

    dependsOn('npmInstall')
    args =  ['-i', './src/main/resources/static/css/tailwind.css', '-o', './src/main/resources/static/css/tailwind.min.css', '--watch']
}

     2 -- I run gradle frontend

     3 -- I saw to next response

22:02:28: Executing 'clean frontend'...

> Task :clean
> Task :nodeSetup UP-TO-DATE
> Task :npmSetup SKIPPED
> Task :npmInstall UP-TO-DATE
> Task :frontend

BUILD SUCCESSFUL in 1s
4 actionable tasks: 2 executed, 2 up-to-date
22:02:30: Execution finished 'clean frontend'.

Expected behavior

I expected to generate the file tailwind.min.js in /src/main/resources/static/css/tailwind.min.css.

Start with the frontend task in build.gradle and run gradle frontend using the listed Tailwind CSS arguments, comparing it with the command without --watch. Check the task output and the expected static/css/tailwind.min.css path; done means the reported watch invocation behaves as intended and produces the expected output.
