I used lastRun when building the project, but I encountered a problem

[cherrol]

This is my configuration

//style.js
const { src, dest, watch, lastRun } = require('gulp');
const less = require('gulp-less');
const sourcemaps = require('gulp-sourcemaps');
const cleanCss = require('gulp-clean-css');
const rename = require('gulp-rename');
const prefixer = require('autoprefixer');
const postcss = require('gulp-postcss');
const gradient = require('postcss-filter-gradient');

const { configStyle } = require('./config');

const compileLess = () => {
  return src(configStyle.source, { since: lastRun(compileLess) })
    .pipe(sourcemaps.init())
    .pipe(less())
    .pipe(postcss([prefixer(), gradient({ angleFallback: false })]))
    .pipe(rename(configStyle.targetName))
    .pipe(sourcemaps.write('./', { sourceRoot: '../' + configStyle.sourceMapPath }))
    .pipe(dest(configStyle.target))
};

exports.watchStyle = () => {
  return watch([configStyle.watch], { ignoreInitial: false }, compileLess);
};

exports.buildStyle = () => {
  return src(configStyle.source)
    .pipe(less())
    .pipe(postcss([prefixer(), gradient({ angleFallback: false })]))
    .pipe(cleanCss())
    .pipe(rename(configStyle.targetName))
    .pipe(dest(configStyle.target))
};

//gulpfile.js
const { task } = require('gulp');

const { buildStyle, watchStyle } = require('./tasks/style');

task('watch', watchStyle);
task('build', buildStyle);

When I run the build task once while running the watch task, the watch task cannot work properly.
The log is normal, but the file is not modified

Hey @SLingGeA, we actually GitHub Discussions enabled for support help, so I've moved this over there. Hopefully a community member can help you debug this problem!
