How do I configure the proxy settings so that Eclipse can download new plugins

Question

I am working with Eclipse 3 7  on an Windows XP environment behind a web proxy   I want to install the Groovy plugin on a newly unzipped Eclipse Indigo  Eclipse Java EE Indigo M4   I added the update site to the Available Software Site list   But Eclipse is not able to retrieve the information of this plugin  and thus the installation is not possible     If I put Native configuration in General  gt  Network Connections  which does not have the Auth option selected  I get the following error when I trying to reach the update site   HTTP Proxy Authentication Required  http   dist codehaus org groovy distributions greclipse snapshot e3 7 content xml HTTP Proxy Authentication Required  http   dist codehaus org groovy distributions greclipse snapshot e3 7 content xml Proxy Authentication Required   So now  I select manual  I define all correct information for the three schemas  HTTP  HTTPS  SOCKS   proxy  port  Auth  User and password  However  when I try to reach the update site  Eclipse is indicating that he is Fetching children of Groovy Eclipse  but keep this status at 0      What is strange is that even if I put a wrong password in the General  gt  Network Connections configuration  I don t get any error message   My questions    What is wrong in my configuration  Is there another way to define the proxy configuration   Is there a way to get more information  to know what Eclipse is trying to do  the workspace  metadata  log doesn t contain any useful information       Another problem  minor however  is that the modifications of the proxy settings seem to be handled only after an Eclipse restart     ps1  Using my browser  I can reach the update site  so it is not blocked by the proxy   ps2  This problem is not related to this plugin  as Eclipse behaves the same way for other plugin   ps3  Here is the content of the workspace  metadata  log when I start Eclipse and try to install the plugin  all these logs are written during the startup  none when Eclipse tries to access the update site    SESSION 2011-05-02 10 38 58 681 ----------------------------------------------- eclipse buildId I20101208-1300 java version 1 6 0 20 java vendor Sun Microsystems Inc  BootLoader constants  OS win32  ARCH x86  WS win32  NL fr FR Framework arguments   -product org eclipse epp package jee product Command-line arguments   -os win32 -ws win32 -arch x86 -product org eclipse epp package jee product   ENTRY org eclipse core net 1 0 2011-05-02 10 39 02 228  MESSAGE System property http proxyHost is not set but should be XXX    ENTRY org eclipse core net 1 0 2011-05-02 10 39 02 228  MESSAGE System property http proxyPort is not set but should be 8080    ENTRY org eclipse core net 1 0 2011-05-02 10 39 02 244  MESSAGE System property https proxyHost is not set but should be XXX    ENTRY org eclipse core net 1 0 2011-05-02 10 39 02 244  MESSAGE System property https proxyPort is not set but should be 8080    ENTRY org eclipse core net 1 0 2011-05-02 10 39 02 244  MESSAGE System property socksProxyHost is not set but should be XXX    ENTRY org eclipse core net 1 0 2011-05-02 10 39 02 244  MESSAGE System property socksProxyPort is not set but should be 8080    ENTRY org eclipse core net 1 0 2011-05-02 10 39 02 244  MESSAGE System property https proxyHost is not set but should be XXX    ENTRY org eclipse core net 1 0 2011-05-02 10 39 02 244  MESSAGE System property https proxyPort is not set but should be 8080    ENTRY org eclipse core net 1 0 2011-05-02 10 39 02 244  MESSAGE System property socksProxyHost is not set but should be XXX    ENTRY org eclipse core net 1 0 2011-05-02 10 39 02 244  MESSAGE System property socksProxyPort is not set but should be 8080    ENTRY org eclipse core net 1 0 2011-05-02 10 39 02 244  MESSAGE System property socksProxyHost is not set but should be XXX    ENTRY org eclipse core net 1 0 2011-05-02 10 39 02 244  MESSAGE System property socksProxyPort is not set but should be 8080    ENTRY org eclipse osgi 2 1 2011-05-02 10 39 02 447  MESSAGE NLS missing message  TaskJobFactory Refreshing repository configuration in  org eclipse mylyn internal tasks ui messages     Edit  If I add the following lines in my eclipse ini file  because of that   it works   -Dorg eclipse ecf provider filetransfer excludeContributors org eclipse ecf provider filetransfer httpclient -Dhttp proxyPort 8080 -Dhttp proxyHost XXX -Dhttp proxyUser XXX -Dhttp proxyPassword XXX -Dhttp nonProxyHosts localhost 127 0 0 1   But why  Does this problem still exists in Eclipse 3 7

I had the same problem  I installed Eclipse 3 7 into a new folder  and created a new workspace  I launch Eclipse with a -data argument to reference the new workspace   When I attempt to connect to the marketplace to get the SVN and Maven plugins  I get the same issues described in OP   After a few more tries  I cleared the proxy settings for SOCKS protocol  and I was able to connect to the marketplace   So the solution for me was to configure the manual settings for HTTP and HTTPS proxy  clear the settings for SOCKS  and restart Eclipse

Just to add to the thread as a POSSIBLE solution  I faced a similar issue when developing on a Linux system that was behind a company firewall   However  using a Windows XP machine  Eclipse was able to access different update sites just fine as both the manual and native network connection providers worked just fine using the company proxy   After stumbling around for some time  I came across a discussion about using NTLMv2 and an implementation to be found at http   cntlm sourceforge net    To whomever posted this  I give much credit to as it helped me get past the issue running on Linux   As a side note  I was using Eclipse 3 6 2   Helios on both the Linux and Windows distros   Best of luck on finding a solution

There is an eclipse ini  sts ini  parameter that can help    -Djava net useSystemProxies true   A lot of effort wasted on this trivial setting each time I change the work environment    See one of the related bugs on eclipse bugzilla
