配置本地 nexus 服务器以从其他远程 nexus 存储库下载工件

Question

我已经在本地安装了 Nexus 存储库并配置了 maven 以使用我的 Nexus 存储库。我正在尝试安装阔叶商业，但总是出现错误。阔叶演示：https://github.com/BroadleafCommerce/DemoSite。

当我使用默认的 Maven 设置文件构建项目时，我可以构建项目。但是使用 nexus local repo，我无法下载阔叶工件。谁能帮我看看我的设置有什么问题？

我的 settings.xml

<settings>
<mirrors>
<mirror>
  <!--This sends everything else to /public -->
  <id>nexus</id>
  <mirrorOf>*</mirrorOf>
  <url>http://localhost:8081/repository/maven-proxy-test/</url>
</mirror>
</mirrors>
<profiles>
<profile>
  <id>nexus</id>
  <!--Enable snapshots for the built in central repo to direct -->
  <!--all requests to nexus via the mirror -->
  <repositories>
    <repository>
      <id>central</id>
      <url>http://central</url>
      <releases><enabled>true</enabled></releases>
      <snapshots><enabled>true</enabled></snapshots>
    </repository>
<repository>
      <id>broadleaf-repo</id>
      <url>http://nexus.broadleafcommerce.org/nexus/content/groups/public</url>
      <releases><enabled>true</enabled></releases>
      <snapshots><enabled>true</enabled></snapshots>
   </repository>
  </repositories>
 <pluginRepositories>
    <pluginRepository>
      <id>central</id>
      <url>http://central</url>
      <releases><enabled>true</enabled></releases>
      <snapshots><enabled>true</enabled></snapshots>
    </pluginRepository>
<pluginRepository>
      <id>broadleaf-repo</id>
      <url>http://nexus.broadleafcommerce.org/nexus/content/groups/public</url>
      <releases><enabled>true</enabled></releases>
      <snapshots><enabled>true</enabled></snapshots>
    </pluginRepository>
  </pluginRepositories>
</profile>
 </profiles>
<activeProfiles>
<!--make the profile active all the time -->
<activeProfile>nexus</activeProfile>

当我构建阔叶项目时，我总是遇到构建错误。

Answer 1

您有 2 个选项，具体取决于您要如何处理。

如果您的 nexus 还应该包含来自 broadleafcommerce 的工件，您必须将其添加为代理存储库：

在 Nexus 中创建一个 Proxy Repository，ID 为 broadleafcommerce，URL http://nexus.broadleafcommerce.org/nexus/content/groups/public 和版本策略 Mixed 在您的settings.xml 中定义您的镜像：

<mirrors>
    <mirror>
      <id>nexus</id>
      <mirrorOf>*,!broadleaf-repo</mirrorOf>
      <url>http://localhost:8081/repository/maven-proxy-test/</url>
    </mirror>
    <mirror>
      <id>broadleafcommerce</id>
      <mirrorOf>broadleaf-repo</mirrorOf>
      <url>http://nexus.broadleafcommerce.org/nexus/content/groups/public/</url>
    </mirror>
</mirrors>

如果您不希望在您的 nexus 存储库中拥有来自 broadleafcommerce 的工件：

以这种方式定义你的镜像：

<mirrors>
    <mirror>
      <id>nexus-group</id>
      <mirrorOf>*,!broadleaf-repo</mirrorOf>
      <url>http://localhost:8081/repository/maven-proxy-test/</url>
    </mirror>
</mirrors>

请注意，<mirrorOf>*,!broadleaf-repo</mirrorOf> 指向您定义的存储库的 ID 并将其排除在外。
