stylelint + gulp-postcss doesn't work for subfolders

I use gulp 3.9.1, gulp-postcss 6.2.0 and stylelint 7.6.0 for SCSS linting. OS is Ubuntu. A related part of my gulp config looks like this:

var postcss = require('gulp-postcss');
var stylelint = require('stylelint');
var postcssReporter = require('postcss-reporter');
gulp.task('styles', function() {
  ...
  var lintProcessors = [
    stylelint(),
    postcssReporter({ clearMessages: true })
  ];

  gulp.src('app/assets_src/styles/**/*.scss')
    .pipe(postcss(lintProcessors, {syntax: scssSyntax}));
  ...
});

The problem: Stylelint works great for files like app/assets_src/styles/file.scss but it doesn’t process files in subfolders like: app/assets_src/styles/blocks/home/file.scss Also the weird thing is that in some very rare times it fires once for such nested files, but then stops working again. I’ve tried to use such paths:

app/assets_src/styles/**/**/*.scss
/app/assets_src/styles/**/*.scss
./app/assets_src/styles/**/**/*.scss

But no luck.

Using this cli command: stylelint 'app/assets_src/styles/**/*.scss' works good and processes subdirectories. So maybe the issue is related to gulp-postcss.

I’m running into the same issue. Though when I run my full gulp build gulp it works flawless everytime.

If I run just my task gulp stylelint it flucuates between 4-8 times it will work correctly.

No solution yet, but I’m assuming it’s gulp-postcss, since like you I tried running it through the CLI and it’s working perfectly as well. I’ll look into it more this weekend.

Below is how my call to postcss and stylelint

        return gulp
            .src('resources/scss/**/*')
            .pipe(postcss([
                stylelint(),
                reporter({ clearMessages: true, throwError: false }),
            ], { syntax: scss }));
        )

Also it’s pretty not obvious how returning a stream is related to proper files processing
