Eclipse Kepler doesn't allow me to install plugins
提问by dorien
Just last week I installed egit with the plugin manager in eclipse (K). Now, I wanted to install ObjectAid. Only, none of my repositories (even the standard ones) are able to connect.
就在上周，我在 eclipse (K) 中使用插件管理器安装了 egit。现在，我想安装 ObjectAid。只是，我的存储库（即使是标准存储库）都无法连接。
"Could not find... url"
I already went to preferences->install/update-> reloaded the urls, but then I get an error as well:
我已经去了首选项-> 安装/更新-> 重新加载了 url，但是我也收到了一个错误：
Unable to read repository at http://download.eclipse.org/tools/cdt/releases/kepler/content.xml.
Unable to read repository at http://download.eclipse.org/tools/cdt/releases/kepler/content.xml.
Failure initializing default SSL context
I also looked at the network settings, changed "native" to "direct", to no avail.
我还查看了网络设置，将“本机”更改为“直接”，但无济于事。
I know I can just download the plugin and install it manually, but that is cumbersome, I would like the network install to work.
我知道我可以只下载插件并手动安装它，但这很麻烦，我希望网络安装能够正常工作。
Could it be some sort of "locked" file somewhere?
它可能是某种“锁定”文件吗？
Update
更新
My git push is also not working (local commit works fine). This is probably related. Strange that the internal browser works though.
我的 git push 也不起作用（本地提交工作正常）。这大概是有关系的。奇怪的是，内部浏览器可以工作。

Could there be a problem with the fact that I also have eclipse juno on this computer? I run it with a different workspace though.
我在这台计算机上也有 eclipse juno 的事实会不会有问题？不过，我使用不同的工作区运行它。

Fantastic! I simply appended the port number 80 to the URL and it works for me! http://download.eclipse.org:80/releases/kepler
极好的！我只是将端口号 80 附加到 URL 后，它对我有用！ http://download.eclipse.org:80/releases/kepler

Possible Solutions:
可能的解决方案：
Try starting eclipse withthe following argument and add it to
eclipse.ini:-vmargs -Djava.net.preferIPv4Stack=trueCheck the port and proxy settingsunder
Window -> Preferences -> General -> Network Connections
尝试使用以下参数启动 eclipse并将其添加到
eclipse.ini：-vmargs -Djava.net.preferIPv4Stack=true检查端口和代理设置下
Window -> Preferences -> General -> Network Connections
You need to make sure that whatever outgoing port(s) your organization allows, you're using one of those, and enter the settings for any proxy your organization requires. Change the port to a usable port like 80
您需要确保您的组织允许的任何传出端口，您正在使用其中之一，并为您的组织所需的任何代理输入设置。将端口更改为可用端口，例如 80

It is a bug in open jdk 1.7from the suse repos. So I installed the jdk 1.7 rpm which is offered by Oracle. Be sure that your eclipse points to the right java version
它bug in open jdk 1.7来自 suse 存储库。所以我安装了 Oracle 提供的 jdk 1.7 rpm。确保您的Eclipse 指向正确的 Java 版本

I had the same symptoms, on Fedora. Installing plugins worked once, then every source failed on the next attempt.
我在 Fedora 上也有同样的症状。安装插件工作一次，然后每个源在下一次尝试时都失败了。
I saw on a forum post to try adding -cleanto eclipse on the command line. Starting with eclipse -cleanput me into a mode where I could not install any software, but after a quit and starting eclipse normally, I could install plugins again without any complaints.
我在论坛帖子上看到尝试-clean在命令行上添加到 eclipse。从eclipse -clean让我进入无法安装任何软件的模式开始，但是在退出并正常启动eclipse之后，我可以再次安装插件而没有任何抱怨。
Looking around, this flag clears out a bunch internal caches in eclipse. As this was only my second time running eclipse, I wonder if I just had bad luck or if it's typically this shaky.
环顾四周，这个标志清除了 eclipse 中的一堆内部缓存。由于这只是我第二次运行 eclipse，我想知道我是运气不好还是通常如此不稳定。

My antivirus firewall was causing this problem.
我的防病毒防火墙导致了这个问题。
After I disabled the firewall of my antivirus, I am able to fetch child of http://download.eclipse.org/releases/mars
禁用防病毒软件的防火墙后，我可以获取http://download.eclipse.org/releases/mars 的子项
