java - 无法让 Maven 与 Nexus OSS 一起工作

Question

我刚刚在我们的一台开发机器上安装了 Nexus 2.1.2，我想将它用作中央存储库的代理，以及我们的快照和版本的内部存储库。我试图按照 Sonatype 的示例进行设置，但是我的 POM 中不断出现一堆错误(我使用的是 Eclipse 和 m2e)。以下是错误:

No plugin found for prefix 'war' in the current project and in theplugin groups [] available from the repositories [local(C:\Users\jwolinsk.m2\repository), nexus(http://xxxxxxdev9:8081/nexus/content/repositories/groups/public)]

No plugin found for prefix 'war' in the current project and in theplugin groups [] available from the repositories [local(C:\Users\jwolinsk.m2\repository), nexus(http://jc1lkddev9:8081/nexus/content/ repositories/groups/public)]

这是我的 settings.xml:

Answer 1

你可以试试这个:

<mirror>
    <id>nexus-local</id>
    <url>http://xxxxxx:8081/nexus/content/groups/public/</url>
    <mirrorOf>external:*</mirrorOf>
</mirror>
<mirror>
    <id>nexus.snapshots-local</id>
    <url>http://xxxxx:8081/nexus/content/repositories/snapshots/</url>
    <mirrorOf>snapshots</mirrorOf>
</mirror>

否则，您是否检查过 Nexus 中的库是否已正确下载。
您可能在 nexus 中遇到网络问题，因此它无法访问网络并下载插件、依赖项。

如果您使用代理，则需要在 Nexus 中配置它:

管理 --> 服务器 --> 默认 HTTP 代理设置
