更新eclipse时出错

我在eclipse中点击更新,我得到一个错误,这是因为我不止一次更新了eclipse.有没有办法修复eclipse并有能力使用更新？

VonC.. 34

您使用的是什么版本的日食？

它已在3.4.1中修复,但在您的情况下,它可能是这个错误.

事实证明原因是一个或多个工件存储库从已知存储库列表中丢失.

解决方法是从列表中删除存储库并再次将其添加回来.这将恢复缺少的工件存储库.

eclipse 3.4.1中可能的解决方法:

1)将更新站点列表导出到bookmarks.xmlfile(Software Updates->Manage sites->Export)
2)停止eclipse
3)删除configuration/.settings/org.eclipse.equinox.p2.*.prefs文件
(注意,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bookmarks.xml文件Software Updates->Manage sites->Import在步骤1中导出的()

正如本答案的评论中mark(此问题的作者)所述,该解决方法是他的问题的解决方案.

其他建议:

[...]解决方案始终是在我的P2 UI中'/'为所有存储库URL 附加一个尾随.
我的感觉是,这个错误是由于未能为repo资源构建可行的URL造成的.有问题的代码不是从UI检查URL字符串,而是假设尾随'/'导致404

最后一个解决方案已经在Eclipse Indigo和Juno中工作(在评论中如下).

又一个解决方案 -

而是导出所有托管站点并将其导回,单击每个选中站点上的"编辑"并在末尾添加"//"

如果您只是添加一个'/',则表示重复的网站,因此'//'

一个巨大的精心设计的应用程序中的小错误如何如此难以调试而又易于解决
