我正在为 maven 使用 yui-compressor 插件，但似乎无法对其进行压缩。所有 js 文件的附加工作正常。它不会删除注释、换行符，也不会缩小 js（即将 var myVar 转换为 var a）。我的配置有问题吗？

我弄清楚发生了什么事。实际上，有一些问题是错误的：首先，整个配置块需要与执行块相邻，而不是在其中。其次，insertNewLine 选项需要在聚合块内。第三，没有被删除的评论是 /*! */ 注释，通常包含许可信息并且 yui-compressor 不会删除。第四，也是最重要的一点，myApp.js 中有一个 eval，它被认为是“邪恶的”并阻止 yui-compressor 压缩。

希望这对人们有所帮助！

我建议您使用 jshint 插件并 lint 您的 js 代码作为压缩 js 的上一步。如果检测到 eval、结束错误的逗号等，则您的 maven 构建在尝试压缩之前失败。
