Maven项目部署到Nexus Repository

标签：

（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

1. 打开WEB管理界面：http://localhost:8081/nexus/index.html
2. 点击右上角Log In进行登录，默认帐号：admin、密码：admin123
3. 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。
4. 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

   <distributionManagement>
    <repository>
        <id>releases</id>
        <name>Nexus Release Repository</name>
        <url>http://localhost:8081/nexus/content/repositories/releases/</url>
    </repository>
    <snapshotRepository>
        <id>snapshots</id>
        <name>Nexus Snapshot Repository</name>
        <url>http://localhost:8081/nexus/content/repositories/snapshots/</url>
    </snapshotRepository>
</distributionManagement>

 settings.xml配置账号密码。注意server的id与repository的id必须对应

<servers>
    <server>
        <id>releases</id>
        <username>admin</username>
        <password>admin123</password>
    </server>
    <server>
        <id>snapshots</id>
        <username>admin</username>
        <password>admin123</password>
    </server>
</servers>

（四）发布到Nexus Repository

• 项目中执行mvn deploy，成功如下所示
