Eclipse下，修改MAVEN 中央倉庫地址，解決maven下載慢問題

好久不寫代碼，突然需要寫點小程式，手生，記錄知識點備忘：

表現：匯入項目到工作空間後，編譯時間顯示maven在下載資源，但速度巨慢，無法忍受。

eclipse中修改maven中央倉庫：2種方式

方式1：(已測試)

作用於所有工作空間：

1、逐項開啟：eclipse->preference->Maven->User Settings。按視窗中的User Settings文字框顯示的路徑，建立settings.xml檔案，或修改路徑後建立檔案。

2、關閉視窗後重新開啟，點擊“open file”，在IDE中開啟該設定檔，出現“could not read settings.xml”不必管。

3、複製下列內容至設定檔，其中<mirror></mirror>部分為國內鏡像。

<settings xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd"><mirrors><!-- mirror | Specifies a repository mirror site to use instead of a given repository. The repository that | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used | for inheritance and direct lookup purposes, and must be unique across the set of mirrors. | --> <mirror>    <id>alimaven</id>    <name>aliyun maven</name>    <url>http://maven.aliyun.com/nexus/content/groups/public/</url>    <mirrorOf>central</mirrorOf>  </mirror>  <mirror>     <id>uk</id>      <mirrorOf>central</mirrorOf>      <name>Human Readable Name for this Mirror.</name>      <url>http://uk.maven.org/maven2/</url>   </mirror>   <mirror>    <id>CN</id>    <name>OSChina Central</name>    <url>http://maven.oschina.net/content/groups/public/</url>    <mirrorOf>central</mirrorOf>  </mirror>  <mirror>    <id>nexus</id>    <name>internal nexus repository</name>    <url>http://repo.maven.apache.org/maven2</url>    <mirrorOf>central</mirrorOf>  </mirror></mirrors><profiles><profile><id>default</id><repositories><repository><id>nexus</id><name>local private nexus</name><url>http://maven.oschina.net/content/groups/public/</url><releases><enabled>true</enabled></releases><snapshots><enabled>false</enabled></snapshots></repository></repositories><pluginRepositories><pluginRepository><id>nexus</id><name>local private nexus</name><url>http://maven.oschina.net/content/groups/public/</url><releases><enabled>true</enabled></releases><snapshots><enabled>false</enabled></snapshots></pluginRepository></pluginRepositories></profile></profiles></settings>

4、"apply"後配置生效，重新編譯即可。
