Working behind a Proxy
Things are getting a bit cumbersome if you are behind a proxy server. Apparently, Java ignores your system wide proxy settings (checked on Linux Mint 16, Windows Server 2008, Mac OS 10.9), that is, you need to configure each piece of software that is involved in your build process separately. Usually, this includes Eclipse and Maven.
Preferences > General > Network Connections and enter your proxy settings.
Active Provider to
Native option did never work for
me (JI apr’14). Users report that one should leave the SOCKS field empty. You may need to restart Eclipse.
Edit your maven settings file (or create if not existing)
~/.m2/settings.xml to look like that:
<?xml version="1.0" encoding="UTF-8"?> <settings xmlns="http://maven.apache.org/SETTINGS/1.1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.1.0 http://maven.apache.org/xsd/settings-1.1.0.xsd"> <proxies> <proxy> <active>true</active> <protocol>http</protocol> <host>localhost</host> <port>3128</port> <nonProxyHosts>127.0.0.1</nonProxyHosts> </proxy> </proxies> </settings>
If neccessary, add
<password> fields (see
also here). Double
check that Eclipse is using the correct settings file (
Preferences > Maven > User Settings).
Things are getting even worse, if you are behind a proxy that uses NTLM authentification (usually Windows based networks). As far as my experience goes (JI apr’14) none of the above java tools can talk to a NTLM based proxy. The only work around is to run a local NTLM-capable proxy on your machine that handles the authentification. There is cntlm which works flawlessly for me (JI apr’14), or Java NTLM Proxy and NTLMaps (both I have not tested).
