Maven dependencies are failing with a 501 error

Question

Recently Maven build jobs running in Jenkins are failing with the below exception saying that they couldn\'t pull dependencies from Maven Central

Answer 1

As stated in other answers, https is now required to make requests to Maven Central, while older versions of Maven use http.

If you don't want to/cannot upgrade to Maven 3.2.3+, you can do a workaround by adding the following code into your MAVEN_HOME\conf\settings.xml into the section:

    maven-https
    
        true
    
    
        
            central
            https://repo1.maven.org/maven2
            
                false
            
        
    
    
        
            central
            https://repo1.maven.org/maven2
            
                false
            
        
     

This will be always an active setting unless you disable/override it in your POM when needed.
