Maven install error: Dependency could not be resolved

Question

I am using Maven 3.1.1. When I run mvn install I get the following error:

D:\\spring source>mvn install
[INFO] Scanning for projects...
[INFO         


        

Answer 1

Where is my Settings.xml?

Windows users

It's in your C:/Users//.m2/settings.xml

Also, this is for specific user. Global one can be present at :

/conf/settings.xml

But changing the User one might solve the issue if you can't find the global one.

Also, equally important, go to Preferences in Eclipse/STS:

• Goto Maven -> User Settings and verify if both global and user settings.xml files are mentioned in the properties, if not mention them by browsing.

1. Proxy Issue

Check Windows Proxy Setting. If there is any proxy which your computer is using then you need to add proxy settings in your settings.xml file too.

Just add this chunk of code in your settings.xml

   
      proxy-id
      true
      http
      ca-something.net
      80
      localhost|10.140.240.90.*
    
   

2. Protocol Issue

Visit http://repo.maven.apache.org/: If it says Https required.

Then, you need to add this chunk of code to your settings.xml inside

  central-secure
  https://repo.maven.apache.org/maven2
  central

Now it should be good to go.

3. None of the above works

Try disconnecting any company private VPN and try mvn clean build.
