Intellij Community can't use http proxy for Maven

Question

I have Intellij IDEA Community installed on a Linux box that needs to use an authenticated proxy to get to the Internet. I have a system-wide proxy on the box that works, and I have the proxy configured in ~/.m2/settings.xml. Maven correctly uses the proxy when I run try it from the command-line.

I have the same proxy configured within Intellij and it gives me the plugins listing correctly. But when I try to sync with the Maven repository withing Intellij I keep getting this:

[WARNING] Unable to get resource 'org.codehaus.mojo:hibernate3-maven-plugin:pom:2.2' 
from  repository restlet (http://maven.restlet.org): Authorization failed: Not   
authorized by proxy.

I went to Settings->Maven and put in the proxy info as properties and that didn't work. I can see by looking at those settings that Intellij is reading my ~./m2/settings.xml fine because it knows where my local repo is (it's in a non-standard place).

Anyone know how I can get this working?

Answer 1

Can you try either removing the proxy setting in settings.xml or the setting in IntelliJ itself.

And then try to sync with the maven repo from within Intellij.

Answer 2

I commented out the proxy config in my ~/.m2/settings.xml file, let the Intellij Proxy info alone, and then supplied the properties in Setting->Maven. Not sure why that worked (nor why the settings.xml wasn't working right) but it's working now.

Answer 3

Could you write me on email (Anton(dot)Makeev(at)jetbrains(dot)com) and sent the settings.xml file, I'll check it.

Thanks, Anton Makeev

Answer 4

I Have found similar issues with the Maven 2.2 integration in intellij 9. I am using 9.0.1

I use intellij behind a corporate firewall/proxy. If I point Intellij's maven conf to use external Maven and maven conf that has the proxy settings inside, intellij fails to download artifacts from any remote repositories.

Had no problems with intellij-8, this only started after the upgrade. The Maven conf has not changed either.

I have to do a Maven build from command line to get any new dependent artifacts into my local repo then use intellij-9.

The Maven 2.2 integration has issues behind proxy servers.
