要从文件夹位置删除文件，可以使用此任务并对其进行调整。

const { src, task } = require( 'gulp' );
const clean = require("gulp-clean");
const logger = require('node-color-log');

function cleanFolderTask() {
    const yourPathRoot = "pathToYourFolder"; //I would recommend using config file to store paths, such as : config.path.artifact.root;
    logger.color('yellow').log(`Cleaning ${yourPathRoot}`);

    return src(yourPathRoot ,{allowEmpty: true},{read: false}).pipe(clean({force:true}));
};

const cleanFolderTask= task('clean:folder', cleanFolderTask);
exports.cleanFolderTask= cleanFolderTask;

要从一个文件夹复制到另一个文件夹，我还将使用上一个任务首先清理目标，然后：

const { src, dest, task } = require( 'gulp');
const logger = require('node-color-log');

function copyFilesTask(callback) {
    let filesLoc = "path/to/your/files"; 
    let filesDest = "path/to/destination"; // I would recommend using config file to store paths, such as : config.path.artifact.files and config.path.solution.files;

    logger.color('yellow').log(`Copy ${filesDest }`);

    src(`${filesLoc}/**/*`)
        .pipe(dest(filesDest), 
        callback());
};

const copyFiles = task('copy:files', copyFilesTask);
exports.copyFiles = copyFiles;
