我個人笨拙的翻譯：如圖位置的node.exe（這個node顯然不是我本地那個）無法loading 這個插件：frontend-maven-plugin
由於pom裏配置它下載的node版本和我本地是一致的。所以我就把它下載的刪了，將我本地的node直接複製過去就解決了。
下面是原來那破插件自己下載的node：
下面是我自己的node，紅色框框是相同部分。
緩存自己的後，再次運行pom.xml就可以了。
補充：frontend-maven-plugin插件的作用自行百度，概況就是本地機器無需安裝node環境，也能自行打包程序。它自己會去下載node輕簡版。
我還特意把我本地的node在環境變量的配置去掉（專門測試這個插件，減少本地node干擾），發現果然能正常打包，這也證明這個插件確實能自行下載node去運行pom.xml，而不去依賴本地環境。
