如何从eclipse市场访问个人捆绑更新站点

Question

当我尝试在Eclipse 3.7的“安装新软件”对话框中访问我的个人更新站点时，出现以下错误，因此无法从该更新站点下载/安装任何插件：

org.eclipse.equinox.p2.core.ProvisionEcception

Unable to read repository at http://marketplace.eclipse.org/user/16293/p2/repo.
Unable to read repository at http://marketplace.eclipse.org/user/16293/p2/repo.
http://marketplace.eclipse.org/user/16293/p2/repo is not a valid repository location.

这似乎不是一个暂时的问题。我从最近2个月左右收到此消息。 我不知道发生了什么变化，因为在那之前它运作得很好。

这是.log中的堆栈跟踪：

出了什么问题？如何再次使用我的市场更新站点？
