I want to install a subversion on my eclipse.
So I went to Help < Install New Software and when I pick the "Galileo - http://download.eclipse.org/releases/galileo" in the "Work with" dropdown, it tells me in the main box "No repository found at http://...".
It is appearing in my available software sites and when I test the connection it returns me an error saying Unknown host.
Can someone please help me, I really need to install that subversion :).

As mention in this thread, this could be a proxy issue:
I assume you mean you used a web browser to get that - if so, is it
configured to use a web proxy? If your browser is using a proxy then
you need to configure Eclipse to use one too (see the General/Network
Connections preference page).
Since 3.5 Galileo, The Network Connection page has been changed to better show the current proxy configuration.
Now if you go to Preferences > General > Network Connections, you are able to see and change Eclipse proxy settings as well as see settings provided by the operating system.
If you want to use your browser or Gnome settings, or you have your proxy configured using environmental variables on Linux, you can see them all in this new UI
So to set your proxy, you can follow this tutorial (How to configure Proxy Settings in Eclipse)
The severity of the bug is downgraded, since there is a workaround. Open the eclipse.ini file and add the following
-Dorg.eclipse.ecf.provider.filetransfer.excludeContributors=org.eclipse.ecf.provider.filetransfer.httpclient
In a few words the above command says that Eclipse can access the web via the *.pac files of the HTTP clients (eg Internet Explorer or Firefox).
To summarize:
Add the above line at the ini file
ensure that your default system http client (eg Internet Explorer) has proxy settings configured
Go to Eclipse Window->Preferences->Network Connection and enter the proxy setting here as well
It should work with this workaround
I'm not sure which Subversion client you use but neither of them can be installed from the main Galileo site. Follow the instructions on the web page of the Subversion plug-in how to install it.

I have managed to get Eclipse Juno connecting to the internet. For this to accomplish, there are many posts here on stackoverflow. here is one of this links:
Eclipse not connecting to internet via proxy
Today i installed Eclipse Kepler on my Windows7 box. But accessing the eclipse marketplace or installing new software does not work.
I am using exactly the same proxy configuration as i used for Eclipse Juno. Juno can access the marketplace but Kepler does not.
The proxy uses NTLM Authentification.
Any one here with similar problem?
No success til now. I am still wondering why Juno can connect whereas Kepler can not:-(
I had same issue. I searched and found this.

This post says don't set SOCKS proxy. I tried this advice, and connection was succeeded.
I did below:
Open Network Connection Settings.
Select Active Provider to "Manual".
Set HTTP/HTTPS proxy.
Clear SOCKS proxy if this is set.(select SOCKS proxy row and click "Clear" button)
Restart Eclipse to apply these settings.
I spent hours trying to use this method suggested by mhanada and although it is correct and should have worked the default Secure Storage associated with eclipse was preventing my proxy credentials from being saved. I advise: Be wary of exceptions being thrown regarding Secure Storage. In my case the errors related to being unable to connect to a remote location where the default secure storage path was. In my case I just deleted the Default Secure Storage information via Preferences > General > Security > Secure Storage > Contents > Delete.
In my case I set it to "native" settings where socks was enabled for proxy. (Internet Explorer->Internetoptions->Connections->LAN-Settings->Proxy Settings). After disabling it there and adding the following lines to eclipse.ini everything works well:
-Dorg.eclipse.ecf.provider.filetransfer.excludeContributors=org.eclipse.ecf.provider.filetransfer.httpclient4
-Dorg.eclipse.ecf.provider.filetransfer.retrieve.closeTimeout=3000
-Dorg.eclipse.ecf.provider.filetransfer.retrieve.readTimeout=3000
In my case the problem started after installing the Spring Tool Suite. Uninstalling it solved the problem.
Version: Kepler Service Release 1
A friend of mine ran into that exact problem (fresh machine with a fresh eclipse Kepler installation, the computer was not behind a firewall or proxy.) It turned out to be an issue with Java 7 update 51, when we used a Java 6 JRE to run eclipse the problem was magically solved.
Another note:
After changing my Windows password, eclipse's Windows-integrated secure storage seemed to have become inaccessible without notice. Apparently this not only made eclipse 'forget' my proxy auth settings but also prevented it from storing the credentials after I set them up again. I could configure them any way I wanted but as soon as I clicked "OK" they were gone again.
The solution for me was to go to General > Security > Secure Storage and click on "Change Password..." for the Windows Integration master password provider. Of course, this wiped all passwords previously stored by eclipse, but it left me with a clean, working Secure Storage and allowed me to successfully set up and store the proxy credentials again.
I had faced the same problem , The issue with my set up was I was using JDK, after repointing to JRE it is working perfectly now.
Proxy Setup- Windows->Preferences->General->Network Connections.
Active Provider-Native, Just make sure HTTP - Dynamic should be checked, remaining all should be Unchecked.
Note: Above Description Tried and tested with Kepler only.
It happened to me because eclipse was using JRE and not JDK.
To force eclipse to use a given VM, edit
<eclipse_root>\eclipse.ini
and add those 2 lines at the top of the file:
-vm
C:/Program Files/Java/jdk1.6.0_45/bin/javaw.exe
Note:
Eclipse using JRE was triggering a:

Did you make sure that you selected the Manual mode in the Active Provider section? Go to the Preferences/General/Network Connections menu again and change that if it is not. I think that part is kind a buggy.
I had this issue, and i changed the proxy settings with password in eclipse.
go to windows-> preferences-> search for "proxy"
open Network connections.
Select Active Provider to Manual.
Set HTTP and HTTPS proxy, system username and password.
(it was not working without username and password in my machine)
Clear SOCKS proxy if its set.
File-> Restart
I'm experiencing some weird problems on using web stuff in Eclipse (Indigo, Indigo SR2 and Juno). My proxy configurations seems to be messed when Eclipse tries to do sth on web.
My browsers stop to communicate and I have to restart my machine in order to restore my Internet access again (or close Eclipse and browser and force the browser to reload proxy configurations). In Eclipse, the communication is unstable, working/not working sometimes.
My "NetWork Connections" are set to Manual, where proxy address, port, auth, user and passord are set to HTTP and HTTPS schemas (I didn't use it for SOCKS due to update issues - see this question).
I have no idea of what is happening and why, and how to fix it. Thanks for helping.
It is very unlikely that Eclipse influences your global settings. If anything outside of Eclipse does not work, should look there for the problem first. Eclipse can either use your system wide settings, or it's own overrides.
I understand your frustration - hard to know what is going wrong.. I really don't see what Eclipse can be doing to cause this though. I can suggest some further troubleshooting steps though.
Can you test the proxy config on any other machine?
Can you browse normally on this machine at other times?
Can you go to the same URL in browser that Eclipse is going to?
Perhaps do you have Eclipse checking all sites for updates (Help > Software) and this is just network slowdown?
When you are experiencing this effect, can you ping outside sites?
I am using Eclipse 3.6. I am trying to download a plug in from an update site, but it won't connect, it keeps saying "Pending" for quite some time.
Not alot of information there. It helps to let us know what you have tried...
I'll quote an answer I gave to a similar question, which contains the basic workarounds:
Can you connect to internet at all through Eclipse?
Open the internal webbrowser. In Eclipse: Window -> show view -> Other -> General: Internal web browser. Look up any normal adress, is it working?
Can you connect to another update site? Try for example Eclipse Emma: http://update.eclemma.org/ Do you see anything there?
What are your proxy preferences? Go to Window -> preferences -> General: Network connections.
The active provider:
Specifies the settings profile to be used when opening connections. Choosing the Direct provider causes all the connections to be opened without the use of a proxy server. Selecting Manual causes settings defined in Eclipse to be used. On some platforms there is also a Native provider available, selecting this one causes settings that were discovered in the OS to be used.
If internet is working fine outside of Eclipse, try changing to Native. After that, try Direct.
Here's one more option to try if none of the efforts above helped. You might be using Eclipse from a Shared Drive (for eg, H:). If so, move/copy it the entire Eclipse directory to C: and try again.
My Eclipse could not connect to internet, nor access Eclipse Marketplace, nor even open ports for Tomcat server. I am behind a corporate proxy and tried many options that I have found on Stack Overflow and other forums but to no avail. I've also tried different versions (Mars, Luna, Kepler and a corporate-provided Kepler).
These are the options I have tried:
Use Direct Connection
Go to Windows > Perferences > General > Network Connections.
Change Active Provider to Direct.
Restart Eclipse.
Set up Manual Proxy
Go to Windows > Perferences > General > Network Connections.
Change Active Provider to Manual.
Input proxy details, including username/password if required.
Clear SOCKS proxy.
Restart Eclipse.
Change Eclipse.ini
Go to Windows > Perferences > General > Network Connections.
Change Active Provider to Native.
Open Eclipse.ini.
Add the following under -vmargs, each on its own line.
-Dorg.eclipse.ecf.provider.filetransfer.excludeContributors=org.eclipse.ecf.provider.filetransfer.httpclient4
-Dhttp.proxyPort=8080
-Dhttp.proxyHost=myproxy
-Dhttp.proxyUser=mydomain\myusername
-Dhttp.proxyPassword=mypassword
-Dhttp.nonProxyHosts=localhost|127.0.0.1
-Djava.net.preferIPv4Stack=true
Restart Eclipse

Add Eclipse to Firewall
Go to Control Panel > Windows Firewall (or your own firewall)
Add Eclipse to whitelist (see https://stackoverflow.com/a/35508990 for Windows Firewall)
Delete Oomph-releated sub folders
Delete all Oomph-releated sub folders in ${user.home}/.eclipse/ folder
For Windows this may be in C:\Users\.eclipse

See my other answer for Eclipse not able to open ports for Tomcat (https://stackoverflow.com/a/37246227/4212710).
If eclipse could not able to connect to internet, following may be one of the reason:
There is a service called "Network Access Protection Agent", which might be blocking eclipse from accessing the internet.
In this case, you can try the following (this worked for me-Windows 7 PC):
1. Click on Windows Start button and search for Administrative Tools and Open it
2. Then open Services
3. Look for "Network Access Protection Agent" service
4. Stop this service
5. Now eclipse should be able to connect to internet
Note: This happens when Windows are not up to date. So after stopping this service, update your Windows, then start this service.
Eclipse is constantly running 'Loading Messages' from what appear to be various plugin sites as well as a main eclipse site (all reference a messages.xml file). Is there a way to disable this? They are never able to actually load as I am behind a proxy, so it just sits there and churn. I've yet to find a solution to this.
Edit:
Most of the time, I have my active provider set to manual. This is required on my end in order to access source code. So I actually have eclipse set up to not use a proxy. Because of this, eclipse can not contact any outside sites (but I don't have a choice on this issue). The active provider is only native when set I need to download a plugin for the first time (or manually update etc).
I'm assuming you're using Eclipse Helios (3.6).
Eclipse 3.6 should be able to detect a proxy.
Under Window -> Preferences, General -> Network Connections, you should see all of the proxy entries and the proxy bypass defined.
Make sure you have the Active Provider as Native.
I use Eclipse daily for software development and those of you that use it know that you download plugins and updates regularly. The company I work for has Bluecoat installed, which blocks all of the updates. However, the update URLs are not blocked in Internet Explorer. With this said, the problem seems to be that Eclipse is not using Windows authentication when it requests updates from the URLs. Is there a way to set Eclipse up so that it acts like IE?
That could be linked to the proxy and not to Bluecoat:
If IE does authorized the access to update URLs, it must do so through an authenticated proxy connection.
If you do have such a setting (proxyname:port , user/password), you should report that setting on your eclipse, in order for p2 within that eclipse to use those same settings.
