Answer 1

您使用的 Eclipse 版本是什么？

已经fixed in 3.4.1 ，但就你而言，它可能是 this bug instead .

It turns out the cause is one or more artifact repositories being lost from the list of known repositories.

The workaround is to remove the repository from the list and add it back again. This restores the missing artifact repository.

Eclipse 3.4.1 中可能的解决方法:

1. 将更新站点列表导出到 bookmarks.xml 文件(软件更新->管理站点->导出)
2. 停止 eclipse
3. 删除 configuration/.settings/org.eclipse.equinox.p2.*.prefs 文件
   (注意，正如 Fredrik 在评论中提到的，对于 Eclipse3.5+，这将是:
   p2\org.eclipse.equinox.p2.engine\.settings
p2\org.eclipse.equinox.p2.engine\profileRegistry\SDKProfile.profile\.data\.setti‌​ngs)
4. 启动eclipse
5. 导入第 1 步中导出的 bookmarks.xml 文件(软件更新->管理站点->导入)

正如mark所述(这个问题的作者)在这个答案的评论中，该解决方法是他的问题的解决方案。

其他建议:

[...] the solution is always to append a trailing '/' to all repository URLs in my P2 UI.
My feeling is that this error is caused by a failure to construct a viable URL to a repo resource. The code in question is not inspecting the URL string from the UI and is assuming a trailing '/' resulting in a 404

这最后一个解决方案已被证实可以在 Eclipse Indigo 和 Juno 中运行(在下面的评论中)。
