我的项目依赖于 Apache Directory Studio 插件。我创建了一个pom.xml文件并将 Apache Directory Studio 更新站点添加为存储库。但是，Tycho 无法加载 Apache Directory Studio 更新站点。

该站点不是 p2 存储库，但只有一个 site.xml。如何在我的构建中使用这个站点？

从主 pom.xml 文件中提取：

<repositories>
    <repository>
          <id>kepler</id>
          <layout>p2</layout>
          <url>http://download.eclipse.org/releases/kepler</url>
    </repository>
    <repository>
         <id>apacheds</id>
         <layout>p2</layout>
         <url>http://directory.apache.org/studio/update/2.x</url> <!-- old-style update site -->
    </repository>
    <repository>
         <id>gef</id>
         <layout>p2</layout>
         <url>http://download.eclipse.org/tools/gef/updates/releases</url>
    </repository>
    <repository>
         <id>nebula</id>
         <layout>p2</layout>
         <url>http://download.eclipse.org/technology/nebula/incubation/snapshot</url>
    </repository>
</repositories>

错误消息来自mvn clean verify：

Tycho 无法针对旧式更新站点进行构建。旧更新管理器的更新站点格式（顺便说一句，在 Galileo 版本中被 p2 取代，即在 2009 年）仅包含 site.xml 索引文件，其中不包含足够的元数据来解决第谷的依赖关系。

有两种方法可以解决此问题：

  • 要求站点的提供者以 p2 存储库格式提供他们的内容。
  • 自己将旧站点格式转换为 p2 存储库，将其放在 HTTP 服务器上，然后引用转换后的站点。

可以使用此处所述的简单存根项目完成转换。
