• 解決方案
  繞了一大圈，拷貝過缺失的文件，下過jar包，以爲不是源是問題，結果還是源的原因，默認的源訪問不了，要改成國內的源。
  打開maven安裝路徑，找到settings.xml文件，在標籤下添加標籤內容。

  <mirror>
  	<id>alimaven</id>
  	<name>aliyun maven</name>
  	<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
  	<mirrorOf>central</mirrorOf>

  	<url>http://maven.aliyun.com/nexus/content/repositories/central/</url>
  </mirror>
  

  修改完配置之後，再編譯就不會報錯了，會顯示“Downloaded xxxxx”。
