我个人笨拙的翻译：如图位置的node.exe（这个node显然不是我本地那个）无法loading 这个插件：frontend-maven-plugin
由于pom里配置它下载的node版本和我本地是一致的。所以我就把它下载的删了，将我本地的node直接复制过去就解决了。
下面是原来那破插件自己下载的node：
下面是我自己的node，红色框框是相同部分。
缓存自己的后，再次运行pom.xml就可以了。
补充：frontend-maven-plugin插件的作用自行百度，概况就是本地机器无需安装node环境，也能自行打包程序。它自己会去下载node轻简版。
我还特意把我本地的node在环境变量的配置去掉（专门测试这个插件，减少本地node干扰），发现果然能正常打包，这也证明这个插件确实能自行下载node去运行pom.xml，而不去依赖本地环境。
