Maven plugin not using Eclipse's proxy setting

问题:

I am using springsource tool suite 2.7.2, based on Eclipse 3.7. The Maven plugin comes now out of the box with Eclipse which is great, and this problem occurred even with previous version of Eclipse.

So here is my issue:

I have set the proxy information in my settings.xml file, and on the command line Maven works just fine. I have also set the same proxy details in the Eclipse configuration itself, and I know that it is correct as well as the updates work with it and not without.

Of course, the Maven plugin in my Eclipse installation is set to use the proper settings.xml file.

But maven from within eclipse just doesn't use the proxy settings from either of those places, which is very annoying every time I change the pom file. Does anyone have a solution for this issue ?

settings.xml

Here is my settings.xml file:

<?xml version="1.0" encoding="UTF-8"?>
  <settings xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

Maven plugin uses a settings file where the configuration can be set. Its path is available in Eclipse at Window|Preferences|Maven|User Settings. If the file doesn't exist, create it and put on something like this:

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      http://maven.apache.org/xsd/settings-1.0.0.xsd">
  <localRepository/>
  <interactiveMode/>
  <usePluginRegistry/>
  <offline/>
  <pluginGroups/>
  <servers/>
  <mirrors/>
  <proxies>
    <proxy>
      <id>myproxy</id>
      <active>true</active>
      <protocol>http</protocol>
      <host>192.168.1.100</host>
      <port>6666</port>
      <username></username>
      <password></password>
      <nonProxyHosts>localhost|127.0.0.1</nonProxyHosts>
    </proxy>
  </proxies>
  <profiles/>
  <activeProfiles/>
</settings>

After editing the file, it's just a matter of clicking on Update Settings button and it's done. I've just done it and it worked :)

Eclipse by default does not know about your external Maven installation and uses the embedded one. Therefore in order for Eclipse to use your global settings you need to set it in menu Settings → Maven → Installations.
