登錄后最重要的事情就是打開遠(yuǎn)程索引下載，操作為選擇菜單Administrator->Repositories，然后在右邊打開的列表中依次選擇type字段為proxy的記錄，在下方的編輯區(qū)中修改"Download
Remote Indexes"值為true，再從這三個(gè)倉庫上點(diǎn)右鍵選擇"Reapir Index"，這一步別忘，Repair
Index后，Nexus會(huì)從后臺(tái)去官方地址下載倉庫索引文件，大概20M大小，根據(jù)網(wǎng)速快慢下載相應(yīng)時(shí)間后選擇倉庫時(shí)會(huì)以樹形目錄的方式顯示倉庫內(nèi)容。(注意：如果repaire-index后,在“browser
index"里仍然看不到東西，要確定/usr/lcoal/sonatype-work/nexus目錄是否有寫權(quán)限
）Central的"Remote storage location"默認(rèn)的是http://repo1./maven2,因這是國外網(wǎng)站，忒慢，如此找到了以下這個(gè)源鏡像：http://repo.maven./maven2 在maven中存在兩個(gè)
settings.xml，一個(gè)位于maven2的安裝目錄conf下面，作為全局性配置。對(duì)于團(tuán)隊(duì)設(shè)置，保持一致的定義是關(guān)鍵，所以
maven/conf下面的settings.xml就作為團(tuán)隊(duì)共同的配置文件。保證所有的團(tuán)隊(duì)成員都擁有相同的配置。當(dāng)然對(duì)于每個(gè)成員，都需要特殊的
自定義設(shè)置，如用戶信息，所以另外一個(gè)settings.xml就作為本地配置。默認(rèn)的位置為：${HOME}
/.m2/settings.xml目錄
<settings>
<servers>
<mirrors>
