问题
I really don't know what's going on with Eclipse 3.5 (3.5.0 or 3.5.1, same issues), but it's been now 2 days that I'm struggling with Eclipse to find a way to make the plugins installation work via the "Install New Software screen"!!! I have visited a lot of forums and blogs, tried many solutions but in vain: each time the current problem disappears and a new one appears.
I'm trying to make it work at my office, so behind proxy. The best advice I got so far is the one regarding the known issue with NTLM proxies: http://wiki.eclipse.org/ECF_Filetransfer_Support_for_NTLMv2_Proxies. I put in place the hint, but now I have a new error message: Eclipse cannot find the repositories at all... For instance here is what I get now with the Galileo update site itself:
org.eclipse.equinox.internal.provisional.p2.core.ProvisionException: No repository found at http://download.eclipse.org/releases/galileo.
at org.eclipse.equinox.internal.p2.repository.helpers.AbstractRepositoryManager.fail(AbstractRepositoryManager.java:380)

at org.eclipse.equinox.internal.p2.ui.sdk.PreloadingRepositoryHandler$2.run(PreloadingRepositoryHandler.java:71)
at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)
Samething with http://download.eclipse.org/eclipse/updates/3.5, or http://download.eclipse.org/tools/mylyn/update/e3.4/ and whatever the site: no one works.
Please somebody help!
PS: Some more details below:
I have the same issue with third party software too... for instance: http://www.epic-ide.org/updates/testing/site.xml.... same error message.
If I go to Preferences > Install / Updates > Available Software Sites, click on whatever the site and on Test Connection I get a ProvisionException with this error message (when I click on details):
Unable to read repository at http://download.eclipse.org/technology/epp/packages/galileo/site.xml. Unable to read repository at http://download.eclipse.org/technology/epp/packages/galileo/site.xml. Server redirected too many times (20)
the solution is:
add following lines to your eclipse.ini file (before -vmargs):
(verified on 3.5 ; 3.5.1; 3.6.2)
-Dorg.eclipse.ecf.provider.filetransfer.excludeContributors=org.eclipse.ecf.provider.filetransfer.httpclient
-Dhttp.proxyPort=8080
-Dhttp.proxyHost=myproxy
-Dhttp.proxyUser=mydomain\myusername
-Dhttp.proxyPassword=mypassword
-Dhttp.nonProxyHosts=localhost|127.0.0.1

We had tons of issues here, namely with the proxy support. We ended-up using Pulse: http://www.poweredbypulse.com/
Pulse has built-in support for a few plugin, however, you can add third-party plugin and even local jar file quite easily.
Strangely it does not always use the built-in Eclipse feature, so sometimes when Eclipse become difficult ( like in our case for the proxy business ), you can work-around it with Pulse.
回答2:
Use the following setting and you will be all set. Go to Window --> Preference --> General --> Network Connection --> select Direct from drop down

Couple of weeks ago I stumbled upon a Problem with Java and a MySQL-Connection. The Problem being that no Connection could be established. Anyway, the fix was to add -Djava.net.preferIPv4Stack=true to the command line.
I just added the same line to eclipse.ini and as it turns out, it also fixes this issue for me. The option name is pretty self-explainitory: It prefers the IPv4 stack over the IPv6 stack. So this solution may not be viable for everyone.
回答4:
I had a similar problem setting up eclipse in the office. I had set up the for HTTP, HTTPS and SOCKS in:
Window>pref>general>network connections
Clearing the proxy settings for SOCKS fixed the problem for me.
回答5:
I had a similar problem setting up eclipse.
I changed: NATIVE connection to MANUAL and cleared the proxy settings for SOCKS in Windows -> Preferences -> General -> Network connection. That fixed the problem for me.
回答6:
I had similar problem. I changed Direct connection to Native and it worked.
Preferences → General → Network Connections.
回答7:
Have you read this post?
http://eclipsewebmaster.blogspot.ch/search?q=wow-what-a-painful-release-this-was-is
Maybe it explains, why it was kinda difficult the last days.
回答8:
I had to turn off my personal firewall and Windows firewall as well, and it worked in the end.
回答9:
i fought with eclipse 3.5.0 (galileo) for days, i had to use this version because I am doing blackberry development and eclipse comes bundle with blackberry specifics so i need to use the package they bundled, which was not 3.5.0 (not the 3.5.1) , BUT SirFabel saved the day, thanks to all who contributed to this post
I used 3.5.0 and did "Set the following system property in you eclipse.ini file: -Dorg.eclipse.ecf.provider.filetransfer.excludeContributors=org.eclipse.ecf.provider.filetransfer.httpclient For more details on this: wiki.eclipse.org/… - Configure only the HTTP and HTTPS proxies. Not SOCKS!! "
and I am able to get through my companies proxy!!!!

Just to add to this as I have had problems with an install of eclipse on my machine.
Specs: Win 7 x64 on macbook pro. The broken eclipse was galileo, and 1 of 4 installations on my machine at the time - the others were all working.
I was not running proxy, so above solution in the question did not work.
I found an answer that said to get updates for eclipse, and that would fix things. I tried this, and eclipse said there were no updates, but then for some reason I can't understand, my plugins could now install.
... more anecdotal evidence of a problem, and a possible solution, however strange ...
回答11:
Its the Windows OS that make the problem. I got the same problem. Then I tried some other app which use JavaVM to connect the internet, and they fails. Try update JRE, you will notice it. If JRE cannot update itself, then there is some socket inaccessibility that prevent internet access apart from using native windows API. I reinstall Win7 and it fixed the problem.
回答12:
finally I got eclipse 3.7 working behind company firewall. I set to true "java.net.useSystemProxies" option on file "net.properties" located on "C:\Program Files\Java\jre6\lib" (this path could be different for your JRE installation). After that,set Active provider to Native on Eclipse preferences. No need to provide any proxy details anywhere, it just pick it up from system default browser settings
回答13:
I meet the same questions in 3.7 on ubuntu 12.04. My Os use a proxy 127.0.0.1,and the eclipse use another proxy 192.168.1.1.
I read the .log for info. It says !MESSAGE System property http.proxyHost is set to 127.0.0.1 but should be 192.168.1.1.
so I change the eclipse net work setting to the same as the system . At last,it works.
回答14:
I also faced the same problem while working with eclips Neon. It got fixed after editing the .ini file with following content:
> -Dhttp.proxyPort=8080
> -Dhttp.proxyHost=myproxy
> -Dhttp.proxyUser=mydomain\myusername
> -Dhttp.proxyPassword=mypassword
> -Dhttp.nonProxyHosts=localhost|127.0.0.1
> -Djava.net.preferIPv4Stack=true
Note: Sometime it may also caused due to the issue with your Network configuration and device. So conform first that your windows firewall is allowing to connect your eclips to the outer world (internet). (Turn off the windows firewall for the instance of time that your computer take to install the file).
回答15:
In my eclipse Luna faced the same issue because of this URL https://sourceforge.net/projects/restfulplugin/files/site/
So i just Disabled the URL that was Shown in the Error From the Available Software Sites.
You may Check the URL or Try with the Updated URL reg to that Exception :)
回答16:
I was getting the error while trying to connect for updates. Just did as in the above answer -
Window-> Preferences-> General-> Network
There the default provider was set as Native. I changed it to direct as my laptop didn't need to connect to any proxy.
Applied and it is working fine.

There is no need of doing such hectic stuffs. Find in your system where there is "SDK Manager".(incase of windows). Suppose your sdk manager is in E:\Android-9. Go to that path double click the SDK manager ;it will automatically start to download from https://dl-ssl.google.com/../..
Initially you will se it is failing. On the window that appears there will be 'settings' menu. Click on that set the proxy and port. and it will start downloading.
The solution in one sentence is "Don't use eclipse for the download;directly use Android sdk manager and your problem is resolved". Let me know if you have any futhur queries on this issue.
