第一次通過命令行創建maven項目。結果，果不其然啊，還是出問題了，不過出問題比沒有出問題強，知道哪裏有問題並學會解決也是一種收獲。

遇到的第一個問題，在從倉庫下載東西的時候會卡住，我開始以為是網速問題，等了好一會兒發現還是沒動靜。突然想起來視頻裏說從默認的中央倉庫中下載失敗率會很高。於是乎采用了視頻裏提到的英國的一個倉庫。果然速度上來了，但還是有點慢，而且遇到了第二個問題。

第二問題是，在從倉庫下載構件的最後出現了如下錯誤：

有人的解決辦法是用阿裏雲的倉庫，於是接著換倉庫。。。。。

換了之後，我去，，，速度飛起啊，順利創建項目。真的要感謝我的馬爸爸搞了這麽個好東西。

配置如下：

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