Recently downloaded m2e(maven integration with eclipse). The version is 3.0.4. My environment is behind a NTLM proxy. Looking like both Eclipse and mavne having issues to work with NTLM proxy. Found maven did not work with the proxy. Tried to set the proxy in settings.xml file like this:
<proxies>
<proxy>
<active>true</active>
<protocol>http</protocol>
<host>proxy.somewhere.com</host>
<port>8080</port>
<username>proxyuser</username>
<password>somepassword</password>
<nonProxyHosts>www.google.com|*.somewhere.com</nonProxyHosts>
</proxy>
</proxies>
It did not work.
Later tried to specify the http proxy information in the JVM parameter.
-Dhttp.proxyPort=8080（your port）
-Dhttp.proxyHost=192.168.19.200（your IP）
-Dhttp.nonProxyHosts=localhost|127.0.0.1（排除localhost，和127.0.0.1使用proxy）
It did not work also.
But I found the command line maven 2.2.1 worked well using the settings.xml.
Later I downloaded a command line maven 3.10, I found the command line maven 3.1.0 did not work also. Both the settings.xml and JVM parameter did not work. So I research more. Later I found out the root cause is that the maven 3.0.4 or above is having issues with the NTLM proxy(There are other types of proxy, here it is NTLM proxy.). For the command line maven 3.1.0, we can download a extension jar file http://repo.maven.apache.org/maven2/org/apache/maven/wagon/wagon-http-lightweight/2.2/wagon-http-lightweight-2.2.jar
and save it to <command line maven home directory>/lib/ext.
and then commane line maven worked well with NTLM proxy.
For the m2e(the integrated maven with eclipse), I have not found any workable solution. Maybe we have to add an external maven installation in m2e. That way we can at least make a workable m2e.
Let me try out.
