Nexus3：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才能使用，仓库成员必须注意顺序！）

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：设置可重复上传

如图：

仓库组：添加仓库成员

在 Maven 中使用 Nexus

1. Maven 配置文件示例：

   	<!-- localRepository
   	| The path to the local repository maven will use to store artifacts.

   	| Default: ${user.home}/.m2/repository

   	<localRepository>D:\Documents\Repository</localRepository>
   
   	<!-- interactiveMode
   	| This will determine whether maven prompts you when it needs input. If set to false,
   	| maven will use a sensible default value, perhaps based on some other setting, for

   	|
   	| Default: true
   	<interactiveMode>true</interactiveMode>

   	<!-- offline
   	| Determines whether maven should attempt to connect to the network when executing a build.
   	| This will have an effect on artifact downloads, artifact deployment, and others.

2. 在 IDEA 中更新 Maven 仓库索引：（先确保 Nexus 3 的仓库状态为“Online - Remote Available”）
