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

This is going to sound like a ridiculous question, but using the SonarLint Eclipse plugin (v3.2.0) on the latest Eclipse (Oxygen), I am unable to add a new SonarQube server connection.
I am working behind a company firewall, but that doesnt appear to be an issue. I am following the steps here and am able to successfully connect to our internal SonarQube instance, provide my credentials, but it is just on the final step, that the 'Finish' button does not seem to do anything, see screen below:
I appreciate there is probably some background processes need to run in order for this Finish to actually finish :) But this doesnt appear to be doing anything...Anyone else experience this issue?
Any before people ask, I've restarted Eclipse/laptop, uninstalled and reinstalled SonarLint plugin etc.
Thanks in advance!
SonarLint in Eclipse are storing credentials in Eclipse secure storage that itself is protected by a master password. So you must reset it or delete it to add a new SonarQube server connection. You can try this step :
In your Eclipse Go to Window > Preferences, filter and find Secure Storage.
In the Tab Contents find and highlight org.sonarlint.eclipse.core, click Delete > Apply > OK. After deletion process is finished, Eclipse will ask if you want to restart the IDE. It is strongly recommended that you restart the IDE and try again to adding SonarQube server in Eclipse.
Thanks.
On my linux machine I had the same issue, because the used master password provider doesn't work properly.
This answer worked for me:
Open Window > Preferences
Go to General > Security > Secure Storage
At Master password providers uncheck the used provider. The enabled provider with the highest priority is the used one [for me it was "Linux Integration (64 bit)"].
Click apply
I also encountered this problem, but was able to work around it.
This is environment in which I was running:
Eclipse Oxygen.1
Linux VM (VirtualBox) on Windows host
Solution that worked for me based on this post:
Uninstall SonarLint.
Reinstall using Help -> Install new software...
On the Install dialog, un-check the option "Show only the latest versions of available software"
Select the older version of SonarLint.
Select Next and continue with the install.
After installing, configure your SonarQube server like normal.
Upgrade to the latest version of SonarLint via Help -> Check for Updates
In my case the problem also concerned the credentials storage but was caused by the Avecto Defendpoint Client. The company restricted the permissions to create subfolders in user home (c:\users<username>). I had to create manually missing subfolders (.sonarlint and .eclipse) after access level elevation and after filling the reason in a text field. Then I had to give the permissions to those folders for myself. Having created them I could proceed with adding server to sonarlint plugin.
I have downloaded the latest eclipse version, eclipse kepler.
But when i try to access the Marketplace inside eclipse or try to install ADT plugin for Android, it gives me this creepy error which is driving me crazy:
Cannot open Eclipse Marketplace
Cannot install remote marketplace locations: Connection failed
This is most often caused by a problem with your internet connection. Please check your internet connection and retry.
Unable to read repository at http://marketplace.eclipse.org/catalogs/api/p.
Connection reset
Connection failed
This is most often caused by a problem with your internet connection. Please check your internet connection and retry.
Connection reset
please put below line to eclipse.ini in the last it worked for me
-Djava.net.preferIPv4Stack=true
I figured out finally that:
Avira Anti-Virus Software was blocking the network requests by eclipse.
After deactivating "enable web protection" in the Anti-Virus,
the stupid Eclipse was able to update itself.
If you are sitting behind a corporate network it could be filtering out requests coming from eclipse. Switching to 3G on my phone made it work for me.
This frustrated me for a while before I stumbled upon this link:
https://www.eclipse.org/forums/index.php/t/783720/
It says clear SOCKS entry in Network connections and be in manual Active Provider.
The SOCKS entry was already clear but after clicking on clear again, it just worked so worth a shot.
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.
I am running Ubuntu 9.10 and I'm attempting to install a plugin for Eclipse 3.5 from a repository that my company created. This worked in the past on this linux box and also works just fine on my laptop which has Windows XP installed.
The exact error message I'm getting in Eclipse is:
Unknown Host: <location of repository>
org.eclipse.equinox.internal.provisional.p2.core.ProvisionException
Any ideas what might be causing something that used to work not to work anymore?
Thanks!
EDIT: Also, it might be useful to know that I can connect to other eclipse plugin repositories fine; it seems that only my company's internal one is the problem.
It is usually due to a proxy used by Eclipse where it shouldn't use it to access a local self-hosted repo.
Try to set the proxy to "Direct" (hence selecting no Proxy entries at all)
Preferences > General > Network Connections,
(so switch from "Native" or "Manual" to "Direct")
Try other link. I got the same error while using link for "Paris, France - Europe". But than I tried with http://emonic.sourceforge.net/updatesite/nchc/site.xml "Tainan, Taiwan - Asia" and all worked just fine.
It's probably this bug: https://bugs.launchpad.net/ubuntu/+source/sun-java6/+bug/486215
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.
