when I go to Install new software and select an update site, I get a "HTTP Proxy Authentication Required" error.

I have searched the internets for quite some time, and I still did not get an answer.

Facts:

  • I get this error for every update site.
  • I am able to access the update site link both in an internal or external browser.
  • I am using the "native" proxy in eclipse network settings.
  • direct proxy in eclipse network settings does not work either.
  • our helpdesk told me that it's not possible to set up the manual proxy in eclipse network settings (or they don't know)
  • I've tried manually inserting a proxy server:port that I found in a proxy.pac file that I've discovered, no luck...
  • I've tried reinstalling Eclipse, re-adding and/or reloading repositories and deleting repo cache dir
  • I'm using: -Djava.net.preferIPv4Stack=true in ini file
  • I've tried mirroring the repositories using both methods, but log file gives the same proxy error

My system: Eclipse for PHP Developers
Version: Luna Service Release 1a (4.4.1)
Build id: 20150109-0600
Windows 7, 64bit

Just add this at the end of your eclipse.ini :

-Dorg.eclipse.ecf.provider.filetransfer.excludeContributors=org.eclipse.ecf.provider.filetransfer.httpclient4

In my case I had to set the proxy also to manual (SOCKS should be unchecked). But then, no more hassle.

It basically disables the default Apache HTTP client and will use an HTTP client based on the JRE URL connection. See: https://wiki.eclipse.org/Disabling_Apache_Httpclient

Edit:

There is a new Apache HTTP client version for which the parameter value has changed:

-Dorg.eclipse.ecf.provider.filetransfer.excludeContributors=org.eclipse.ecf.provider.filetransfer.httpclient45

To disable both use:

-Dorg.eclipse.ecf.provider.filetransfer.excludeContributors=org.eclipse.ecf.provider.filetransfer.httpclient45,org.eclipse.ecf.provider.filetransfer.httpclient4

I could solve the same problem by going to "Windows" → "Preferences" → "Network Connections" and set "Active Provider" to "Direct". See more details and a screenshot in my answer here.

  1. Switch to the manual proxy options
  2. Enter your proxy, user and password
  3. Do it for al except SOCKS. SOCKS you may leave empty.

I've tried a lot of solutions in Google, but nothing :( I was going to forget about eclipse, but suddenly it worked :)

In the end I talked to a guy who manages the proxy settings in our company and luckily he did some changes to the proxy server and now I'm able to install addons & update software from within eclipse :-)

For my proxy settings, I HAD to leave SOCKS proxy configuration empty after entering manual proxy settings for both HTTP and HTTPS. Leaving them all empty didn't work, and filling them all out didn't work either.

It worked for me using this in eclipse.ini:

-Dorg.eclipse.ecf.provider.filetransfer.excludeContributors=org.eclipse.ecf.provider.filetransfer.httpclient45,org.eclipse.ecf.provider.filetransfer.httpclient4

    _Note:_ This is basically the same answer as @ViToni's above, but updated based on the latest version of the Apache HTTP client. – Jeremy Caney May 21 '20 at 00:47

If you are using eclipse through a virtual machine, then set the network settings to manual in Eclipse. That should solve the issue.
