C:\software\apache-maven-3.0.3\conf\settings.xml I have enabled proxies here as:

….


<proxies>
    <!-- proxy
     | Specification for one proxy, to be used in connecting to the network.
     |-->
    <proxy>
      <id>optional</id>
      <active>true</active>
      <protocol>http</protocol>      
      <host>www.BT.co.uk</host>
      <port>80</port>
      <nonProxyHosts>localhost|google.com</nonProxyHosts>
    </proxy>

  </proxies>

What is the problem I am facing here? Why it is not downloading?

Nice question with all relevant information provided. Please add your solution also as an answer and accept so someone else having this problem has an easier time finding it. – Millicentmillie

Answer 1

Found solution:

Solution #1:

issue was with proxy in settings.xml file:

<host>webproxy</host>

to get host goto IE->tools->connection->LAN settings->advanced->http.

=====

Solution #2:

if auto configured proxy is given: then

1> open IE(or any browser)

2> get the url address from your browser through IE->Tools->internet option->connections->LAN Settings-> get address and give in url eg: as http://autocache.abc.com/ and enter, a file will be downloaded with .pac format, save to desktop

3> open .pac file in textpad, identify PROXY:

In your editor, it will come something like:

   return "PROXY web-proxy.ind.abc.com:8080; PROXY proxy.sgp.abc.com:8080"; 

4> go to Maven settings.xml and enter as:

<proxy>
      <id>optional</id>
      <active>true</active>
      <protocol>http</protocol>          
      <host>web-proxy.ind.abc.com</host>
      <port>8080</port>          
</proxy>

5> run mvn:install through command prompt or run through eclipse.

=====

Solution #3:

For any other issues delete maven local repository and run mvn:install again.

Also uncomment the proxies tag – Particiaparticipant

Answer 2

Clearly this is an issue of proxy. Either use VPN or edit procy setting in setting.xml. I searched lot about this error. Finally, I used VPN(Virtual private network ) to disable the proxy and was able to use cemtral repository of Maven.

Answer 3

Window-Preferences-Maven-User Settings. Check, does settings.xml exists? if eclipse says no, get settings.xml from you friend or set the path to it.

Answer 4

Try checking proxy settings in settings.xml file located under following directory:

C:\Users\UserName\.m2

Answer 5

I just copied setting.xml which comes under "\apache-maven-3.1.1\conf" directory, to the directory "${user.home}/.m2/)" of windows machine and change the required proxy setting according to my network as below and it worked for me.

<proxy>
  <id>optional</id>
  <active>true</active>
  <protocol>http</protocol>
  <host>www-proxy.xxxx</host>
  <port>8080</port>
</proxy>

Answer 6

We have observed that the maven project creation fails when it tries to download the archtype from this URL: Maven Repository which falls under "https" protocol.

So solution #2 mentioned above worked only after a little change to the settings.xml. Instead of using "http" protocol I have to use "https"

<proxy>
  <id>optional</id>
  <active>true</active>
  <protocol>https</protocol>          
  <host>web-proxy.ind.abc.com</host>
  <port>8080</port>          

Hope it helps someone.

Note: Make sure that you check the following internet settings.

Internet Explorer > Internet Options > Connections [TAB] > LAN Settings > Under Proxy server check Use proxy server for LAN > Advanced > Check "same proxy server for all protocols" and Click OK.

Answer 7

Adding below under proxy tag in settings.xml worked for me

<proxy>
  <id>optional</id>
  <active>true</active>
  <protocol>https</protocol>          
  <host>web-proxy.ind.abc.com</host>
  <port>8080</port>  
</proxy>
