我正在尝试构建一个插件+功能，它依赖于com.android.ide.eclipse.adt包。为此，我已将ADT存储库添加到主pom.xml中：
<repository>
  <id>adt</id>
  <layout>p2</layout>
  <url>http://dl-ssl.google.com/android/eclipse</url>
</repository>

现在编译失败，并显示以下错误：

我已经尝试按照这个主题的建议：https://groups.google.com/group/adt-dev/tree/browse_frm/month/2012-07/39c71d32169b9569?rnum=51&_done=/group/adt-dev/browse_frm/month/2012-07?&pli=1，并在http://dl.dropbox.com/u/1236385/adt创建了一个p2更新站点，但错误仍然存在。

为什么找不到 com.android.ide.eclipse.adt？
以防万一，这里是主POM的链接。

旧式的更新站点只有关于构件依赖性的不完整元数据。然而，Tycho需要完整的依赖性元数据来进行其依赖性解析机制，因此无法使用旧式的更新站点。Dropbox站点可能采用现代p2存储库格式，但它包含相同的不完整元数据（在p2术语中，这些具有不完整元数据的条目称为“部分IU”）。在Tycho 0.18.0之前，这些部分IU会被默默地丢弃，导致描述的解析问题。这已经在Tycho 0.18.0中得到改进：从那个版本开始，Tycho将失败并显示指向包含不完整元数据的存储库的错误消息。
要解决您的问题，最好向项目提供适当的p2存储库。p2提供了不同的发布应用程序来完成此操作。理论上，您也可以自己调用发布应用程序，但这确实只是一个临时解决方法。
未来在处理p2存储库时，可以参考以下提示：Igor的p2浏览器是一个非常好用的工具，可以帮助您分析它们。 - oberlies
