清理 dist
$ npm install clean-webpack-plugin --save-dev
script/webpack.config.js
const { CleanWebpackPlugin } = require(‘clean-webpack-plugin’);
module.exports = {
// …
plugins: {
new CleanWebpackPlugin()
}
};
Tips
由于 webpack 使用的是^5.21.2 版本，在使用该插件时，会提示clean-webpack-plugin: options.output.path not defined. Plugin disabled...，暂时还未解决。

最后
现在其实从大厂招聘需求可见，在招聘要求上有高并发经验优先，包括很多朋友之前都是做传统行业或者外包项目，一直在小公司，技术搞的比较简单，没有怎么搞过分布式系统，但是现在互联网公司一般都是做分布式系统。
所以说，如果你想进大厂，想脱离传统行业，这些技术知识都是你必备的，下面自己手打了一份Java并发体系思维导图，希望对你有所帮助。
