Eclipse and proxy

Question

I run my Eclipse on a Linux computer behind a company proxy. This proxy does not need authentication, it simply needs to be set. But in Eclipse some functionalities can't connect to the Internet. When I check the same URL with e.f. curl and the same proxy settings everything works fine.

I defined the proxy:

• in /etc/environment, both http_proxy and https_proxy
• in Eclipse in Window / Preferences / Network connection / Manual. For http and https, not for socks
• in settings.xml, I can see from the preferences that this file gets applied

Eclipse can connect to the Internet:

• in the Marketplace
• for update checks and Installation

Eclipse is unable to reach the Internet:

• in the "Web Browser" view
• in m2e

Any ideas where I missed a special setting ? I do all of this in STS 3.9, which has Eclipse 4.7

Answer 1

I am not sure about the browser view, but m2e/Maven uses proxy settings that are defined in the settings.xml file for Maven.

In Eclipse/STS, you can specify which settings.xml file m2e should use in the preferences for the Maven support.
