Removing NTLM from Eclipse's

Question

I\'m having an issue trying to connect through a proxy from Eclipse 3.6. The proxy supports both NTLM and Basic Auth schemes.

Eclipse seems to prefer NTLM auth sche

Answer 1

The problem is that standard Eclipse HTTP client can't manage the so named HTLM proxies. The method, proposed by @VonC was good till Kepler version of Eclipse.

The trick is to turn off the Eclipse HTTP client. But starting from Kepler, its name had changed. Add the following to the eclipse.ini file:

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

Also look here for a very good explanation and here for an "official" explanation of the Eclipse team.

You don't need to set the proxy parameters in the eclipse.ini. The settings in Windows-preferences-General-Net are enough. But you should check the global proxy settings on the OS, paying attention to possible automatic settings.

Answer 2

I don't know about the Basic Auth, but regarding NTLM proxy, check the bug 281384, also discussed at length in bug 281472.

It introduces a workaround for NTLMv2 Proxies.

-Dorg.eclipse.ecf.provider.filetransfer.excludeContributors=org.eclipse.ecf.provider.filetransfer.httpclient
-Dhttp.proxyPort=8080
-Dhttp.proxyHost=myproxy
-Dhttp.proxyUser=mydomain\myusername
-Dhttp.proxyPassword=mypassword
-Dhttp.nonProxyHosts=localhost|127.0.0.1

The first property disables the httpclient provider (and so uses the URLConnection-based provider, which does have support for NTLMv2 proxies),
and the next 5 properties are as specified by Sun for the URLConnection-based provider.
