eclipse 更新eclipse时出错

Error when updating eclipse

提问by IAdapter

I click update in eclipse and I get an error, it's because I updated eclipse more than once. Is there any way to fix eclipse and have the ability to use update?

我在 Eclipse 中单击更新，但出现错误，这是因为我不止一次更新了 Eclipse。有什么办法可以修复eclipse并有能力使用update吗？

回答by VonC

What version of eclipse are you using ?

你用的是什么版本的eclipse？

It has been fixed in 3.4.1, but in your case, it could be this bug instead.

它已在 3.4.1 中修复，但在您的情况下，它可能是这个错误。

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.

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重新添加。这将恢复丢失的工件存储库。

A possible workaround in eclipse 3.4.1:

eclipse 3.4.1 中可能的解决方法：

1. export the update site listing to bookmarks.xmlfile (Software Updates->Manage sites->Export)
2. stop eclipse
3. remove configuration/.settings/org.eclipse.equinox.p2.*.prefsfiles
   (Note, as mentioned by Fredrikin the comments, for Eclipse3.5+, this would be:
   p2\org.eclipse.equinox.p2.engine\.settings
p2\org.eclipse.equinox.p2.engine\profileRegistry\SDKProfile.profile\.data\.setti??ngs)
4. start eclipse
5. import the bookmarks.xmlfile (Software Updates->Manage sites->Import) that was exported in step 1

1. 将更新站点列表导出到bookmarks.xml文件 ( Software Updates->Manage sites->Export)
2. 停止日食
3. 删除configuration/.settings/org.eclipse.equinox.p2.*.prefs文件
   （注意，如提及弗雷德里克的意见，对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. 开始日食
5. 导入在步骤 1 中导出的bookmarks.xml文件 ( Software Updates->Manage sites->Import)

As mentioned by mark(author of this question) in the comments of this answer, that workaround was a solution for his problem.

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

Other advice:

其他建议：

[...] the solution is always to append a trailing '/'to allrepository 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

[...] 解决方案始终是在我的 P2 UI 中'/'为所有存储库 URL附加一个结尾。
我的感觉是这个错误是由于未能构建到 repo 资源的可行 URL 引起的。有问题的代码没有检查 UI 中的 URL 字符串，而是假设尾随 '/' 导致 404

This last solution is confirmed working in Eclipse Indigo and Juno (below in the comments).

最后一个解决方案在 Eclipse Indigo 和 Juno 中得到确认（在评论下方）。

回答by xask

Yet another solution -

还有一个解决方案——

Instead exporting all managed sites and importing them back, click on 'edit' on each checked site and add '//' at the end

而不是导出所有托管站点并将它们导入回来，请单击每个选中站点上的“编辑”并在末尾添加“//”

If you just add a '/' it says duplicate site therefore the '//'

如果您只是添加一个“/”，它表示重复站点，因此“//”

Though this question is answered a long back, wanted to share my experience thinking that it may save some one' day :)

虽然这个问题很久以前就得到了回答，但我想分享我的经验，认为它可以节省一些时间:)

Some times it could also be possible due to the incorrect proxy settings. In my case (Eclipse 3.6/Helios), Eclipse preference file $ECLIPSE_HOME$/configuration/.settings/org.eclipse.core.net.prefsis having proxy details,

有时也可能由于代理设置不正确。就我而言（Eclipse 3.6/Helios），Eclipse 首选项文件$ECLIPSE_HOME$/configuration/.settings/org.eclipse.core.net.prefs包含代理详细信息，

proxyData/HTTP/hasAuth=true
systemProxiesEnabled=true
proxyData/HTTP/host=proxy.domain.net
org.eclipse.core.net.hasMigrated=true
eclipse.preferences.version=1
proxiesEnabled=true
proxyData/HTTP/port=9119
nonProxiedHosts=

When I deleted the file after closing the Eclipse, then onwards I m able to download the plugins

The backslash thing in the exported bookmarks file fixed it for me.

导出的书签文件中的反斜杠为我修复了它。

I had the same problem (well similar as I was just trying to install subclipse). VonC's tip "Other advice" did it for me.

我遇到了同样的问题（与我只是尝试安装 subclipse 非常相似）。VonC 的提示“其他建议”为我做到了。

1. Export sites to bookmarks.xml
2. Edit this file and append a forward slash at the end of every URL where it is missing.
3. Delete all sites
4. Re-import edited bookmarks.xml
5. Sigh with relief as it works.

1. 将站点导出到 bookmarks.xml
2. 编辑此文件并在每个缺少它的 URL 的末尾附加一个正斜杠。
3. 删除所有站点
4. 重新导入编辑过的 bookmarks.xml
5. 当它起作用时松了一口气。

回答by Sandeep Jindal

I had the same problem. After exporting and importing bookmarks, the problem did not get resolved. but I started getting error 'Connection refused'.

我有同样的问题。导出和导入书签后，问题没有得到解决。但我开始收到错误“连接被拒绝”。

On further thoughts I found that my antivirus is not allowing eclipse to talk to internet. Disabling antivirus made it work.

经过进一步思考，我发现我的防病毒软件不允许 eclipse 与互联网通话。禁用防病毒软件使其工作。

I had a similar problem over the last couple months, but ignored it until I really needed PyDev to work on my laptop today.

在过去的几个月里，我遇到了类似的问题，但一直忽略它，直到我今天真的需要 PyDev 在我的笔记本电脑上工作。

I tried the solutions above to no avail and then I found something odd:

我尝试了上面的解决方案无济于事，然后我发现了一些奇怪的事情：

In (Window->Preferences->Install/Update->Available Software) I noticed that the box for 'PyDev Update Site' AND another one right below it with the location 'file:/updates' were both checked, causing a duplicate of most or all update URLs. After un-checking the box with the location 'file:/updates' I was able to update from (Help->Check for Updates) which then successfully installed the latest version of PyDev.

在 (Window->Preferences->Install/Update->Available Software) 中，我注意到“PyDev 更新站点”框和位于其下方的另一个位置为“file:/updates”的框都被选中，导致重复大多数或所有更新 URL。在取消选中带有位置“文件：/更新”的框后，我能够从（帮助->检查更新）进行更新，然后成功安装了最新版本的 PyDev。

This solution might not be applicable to PyDev updates alone and could hopefully help others with similar issues.

此解决方案可能不适用于 PyDev 更新，并有望帮助其他有类似问题的人。

I just had the same problem, I diabled my ZoneAlarm Firewall, and it connected OK!

我刚刚遇到了同样的问题，我关闭了 ZoneAlarm 防火墙，并且连接正常！

Is there some kind of rule I need to add into my firewall to stop it blocking eclipse? It never used to do this, everything was working find until last week (Sept 25th (ish) 2012)

我需要在防火墙中添加某种规则来阻止它阻止日食吗？它从来没有这样做过，直到上周（2012 年 9 月 25 日（ish）），一切都在工作

When I encountered a similar problem I add the following repository to my available update site. http://dist.springsource.com/release/TOOLS/update/e4.4/.

当我遇到类似的问题时，我将以下存储库添加到我的可用更新站点。 http://dist.springsource.com/release/TOOLS/update/e4.4/。

Make sure the slash in at the end of the URL.

确保 URL 末尾有斜杠。
