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 :)

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

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

I had to turn off my personal firewall and Windows firewall as well  and it worked in the end

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

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

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

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

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

I also faced the same problem while working with eclips Neon  It got fixed after editing the  ini file with following content    gt     -Dhttp proxyPort 8080   gt     -Dhttp proxyHost myproxy   gt     -Dhttp proxyUser mydomain myusername   gt     -Dhttp proxyPassword mypassword   gt     -Dhttp nonProxyHosts localhost 127 0 0 1   gt     -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

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
