Nexus2：使用

初始使用

第一次使用 Nexus 3 需要进行一点配置，才能更好地使用它：

1. 添加存储位置配置：

   

2. 添加仓库：（可以为不同的仓库选择不同的存储位置）

   

   1. 添加代理（proxy）仓库；
      • （应添加“Mavne - Publish Maven Indexer files”类型的任务，以更新其索引）
   2. 添加宿主（hosted）仓库；
      • （应设置其为“Allowed redeploy”）
   3. 添加仓库组（group）；
      • （应为其添加不同的仓库成员）

代理仓库：添加任务更新远程索引

代理仓库状态：

1. “Online - Remote Available”：可用；
2. “Online - Ready to Connect”：不可用；

如图：

如此，更新远程索引之后，才能确保代理仓库的状态可用。

宿主仓库：设置可重复部署

如图：

仓库组：添加仓库成员

如图：

• 需注意成员仓库的顺序：“建议将‘宿主仓库’置于‘代理仓库’之前。（使用时：先查找‘宿主仓库’再查找‘代理仓库’）”

网络代理

有时候局域网是不能直接访问网络的，需要通过防火墙代理来上网，这个时候就需要在 Nexus 里配置代理来访问中央仓库和索引文件了。

如图：

项目配置

pom.xml 示例：（展开/隐藏）

...
	<repositories>
		<repository>
			<id>public</id>
			<url>http://localhost:8090/nexus/content/groups/public/</url>
			<releases>
				<enabled>true</enabled>
			</releases>
			<snapshots>
				<enabled>true</enabled>

			<name>Nexus Snapshot Repository</name>
			<url>http://localhost:8090/nexus/content/repositories/snapshots/</url>
		</snapshotRepository>
	</distributionManagement>
...

1. <repositories> 用于依赖下载；
2. <distributionManagement> 用于部署上传；
   • <id> 必须与 setting.xml 中 <server> 下 <id> 一致；
