（一）下载并安装Nexus Nexus只需下载war包放到tomcat服务器上便可。 （二）配置Nexus Repository 打开WEB管理界面：:8081/nexus/index.html 点击右上角Log In进行登录，默认帐号：admin、密码：admin123 点击左侧Repositories项 -> central仓库 -> Configuration -> Download Remote Indexes=True -> Save，表示下载远程仓库的索引。 右键central仓库 -> Update Index，更新远程仓库索引到本地，这一步能够加速本地索引。 说明： 新搭建的neuxs环境只是一个空的仓库，需要手动和远程中心库进行同步，nexus默认是关闭远程索引下载，最重要的一件事情就是开启远程索引下载。 找到右边仓库列表中的三个仓库Apache Snapshots，Codehaus Snapshots和Maven Central，然后再没有仓库的configuration下把Download Remote Indexes修改为true。然后在这三个仓库上分别右键，选择Repari Index，这样Nexus就会去下载远程的索引文件。右键仓库 -> Update Index，更新远程仓库索引到本地，这一步能够加速本地索引。 新建公司的内部仓库，步骤为Repositories –> Add –> Hosted Repository，在页面的下半部分输入框中填入Repository ID和Repository Name即可，另外把Deployment Policy设置为Allow Redeploy Nexus中仓库组的概念是Maven没有的，在Maven看来，不管你是hosted也好，proxy也好，或者group也好，对我都是一样的，我只管根据groupId，artifactId，version等信息向你要构件。为了方便Maven的配置，Nexus能够将多个仓库，hosted或者proxy合并成一个group，这样，Maven只需要依赖于一个group，便能使用所有该group包含的仓库的内容。 （三）在项目中配置Nexus Repository的信息 项目pom文件配置distributionManagement releases Nexus Release Repository :8081/nexus/content/repositories/releases/ snapshots Nexus Snapshot Repository :8081/nexus/content/repositories/snapshots/ settings.xml配置账号密码。注意server的id与repository的id必须对应 releases admin admin123 snapshots admin admin123 （四）发布到Nexus Repository 项目中执行mvn deploy，成功如下所示 [INFO] --- maven-deploy-plugin:2.7:deploy (default-deploy) @ tenpay --- Uploading: :8081/nexus/content/repositories/releases/com/capital/tenpay/1.2/tenpay-1.2.jar Uploading: :8081/nexus/content/repositories/releases/com/capital/tenpay/1.2/tenpay-1.2.pom Uploaded: :8081/nexus/content/repositories/releases/com/capital/tenpay/1.2/tenpay-1.2.pom (2 KB at 9.7 KB/sec) Uploaded: :8081/nexus/content/repositories/releases/com/capital/tenpay/1.2/tenpay-1.2.jar (39 KB at 124.4 KB/sec) Downloading: :8081/nexus/content/repositories/releases/com/capital/tenpay/maven-metadata.xml Downloaded: :8081/nexus/content/repositories/releases/com/capital/tenpay/maven-metadata.xml (347 B at 4.3 KB/sec) Uploading: :8081/nexus/content/repositories/releases/com/capital/tenpay/maven-metadata.xml Uploaded: :8081/nexus/content/repositories/releases/com/capital/tenpay/maven-metadata.xml (376 B at 7.8 KB/sec) [INFO] ------------------------------------------------------------------------ [INFO] BUILD SUCCESS
