Eclipse (Neon) Marketplace inaccessible through proxy [message #1736261]

Hi guys!

I've just installed Eclipse Neon and unfortunately I can't access the marketplace. We're using a company-wide proxy and there have been problems with previous Eclipse versions as well. However those problems could be circumvented by setting the parameter

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

at the end of the eclipse.ini (vmargs section).

At a first glance the situation is identical with Neon - without the parameter any connection to the internet fails (proxy authorization required). Once it's set everything seems to work including software updates, reloading available software sites and even browsing with the internal browser.

As soon as I try to open the Marketplace I get an error, though:

Cannot open Eclipse Marketplace
Cannot install remote marketplace locations: Cannot complete request to http:// marketplace.eclipse .org/catalogs/api/p: Unexpected response content: Parse result is null.
Cannot complete request to http://marketplace.eclipse.org/catalogs/api/p: Unexpected response content: Parse result is null.
Unexpected response content: Parse result is null.
Received response begins with:

1: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http:// www.w3 .org/TR/html4/loose.dtd">
2: <html>
3:   <head>

I'm pretty certain eclipse should be able to reach the mentioned url - when I try to access it via the internal browser it loads correctly...

Does anyone have any idea what's going wrong? Does the Marketplace handle the connection differently?

(Had to add spaces to the message urls since I'm not allowed to post urls.)

Hello,

I have the same problem. with eclipse mars everything worked perfectly finde but with neon I cannot open the marketplace through the proxy. when I use our guest-Wifi I can enter the marketplace. So it seems to be a proxy problem.
Is there a way to force eclipse neon into using the https-webside?

I'm also experiencing the same problem.

behind a corporate firewall
added the -Dorg.eclipse.ecf.provider.filetransfer.excludeContributors=org.eclipse.ecf.provider.filetransfer.httpclient4 parameter to eclipse.ini
trying to access the marketplace gives the same error

I have the same problem! with eclipse mars everything worked very good, but with neon I cannot open the marketplace through the proxy (advanced.name/ru). when I use our guest-Wifi I can enter the marketplace. So it seems to be a proxy problem, or is it an error with my settings?

Hi Dmitriy,

there is currently a bug fix avaiable for the problem - just follow the link of boris monti's post - in comment #8: "The fix is available on http://download.eclipse.org/mpc/neon".

For me everything works fine with the fix installed.

As far as I know it will be integrated in the next version of Eclipse (presumably 4.6.1).
