If you created new settings xml file instead of copy it from somewhere else  remember to put the  tag inside        lt 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                         https   maven apache org xsd settings-1 0 0 xsd  gt         lt proxies gt                         lt  proxies gt   lt  settings gt

I had the same error  In my case I am using Netbeans  7 1 2  I am posting this because maybe someone end up here same as I did   I tried to configure the proxy options from the GUI  but the documentation says that maven doesn t read those  So I checked the NetBeans FAQ here    What mainly you have to do is create  if it does not exist  a settings xml under   user home  m2 settings xml   if you don t have it you can copy from   netbeans home java maven conf settings xml   then uncomment if you already have it otherwise just fill this section    lt proxies gt    lt proxy gt      lt active gt true lt  active gt      lt host gt myproxy host net lt  host gt      lt port gt 80 lt  port gt    lt  proxy gt   lt  proxies gt    you have to check your proxy configuration and replace it there

I wouldn t advise you to do this but on my personal computer I disabled the firewall so that maven could get the required plugins

Mac OSX 10 7 5  I tried setting my proxy in the settings xml file  as mentioned by posters above  in the  conf directory and also in the    m2 directory  but still I got this error  I downloaded the latest version of Maven  3 1 1   and set my PATH variable to reflect the latest install  and it worked for me right off the shelf without any error

I had the same issue in Windows  and it worked since my proxy configuration in settings xml file was changed  So locate and edit the file inside the  conf folder  for example   C  Program Files apache-maven-3 2 5 conf   lt proxies gt       lt  -- proxy        Specification for one proxy  to be used in connecting to the network              lt proxy gt         lt id gt optional lt  id gt         lt active gt true lt  active gt         lt protocol gt http lt  protocol gt         lt username gt jorgesys lt  username gt         lt password gt supercalifragilisticoespialidoso lt  password gt         lt host gt proxyjorgesys lt  host gt         lt port gt 8080 lt  port gt         lt nonProxyHosts gt local net some host com lt  nonProxyHosts gt       lt  proxy gt      -- gt     lt  proxies gt     In my case i had to chage from port 80 to 8080 If you can  t edit this file that is located inside  program files you can make a copy  edit the file and replace the file located into  program files folder

I had a similar issue with Eclipse and the same steps as Sanders did solve it  It happens because the proxy restricts call to maven repository   Go to D  Maven apache-maven-3 0 4-bin apache-maven-3 0 4 conf  ie your maven installation folder   Copy settings xml and paste it in  m2 folder  which is in the users folder of your windows machine  Add the proxy setting   Something like this     lt proxies gt       lt  -- proxy       Specification for one proxy  to be used in connecting to the network       -- gt       lt proxy gt               lt active gt true lt  active gt         lt protocol gt http lt  protocol gt         lt username gt your username lt  username gt         lt password gt password lt  password gt             lt host gt proxy host net lt  host gt         lt port gt 80 lt  port gt         lt  proxy gt      lt  proxies gt
