Connection timing out while connecting to Maven repository

Question

I am trying to build my project in my local system using the below command

mvn clean install -Dmaven.test.skip=true

It fails with the below error. It is failing to connect to repo.maven.apache.org.

I pinged to the server repo.maven.apache.org, I can see the response back.

I am using maven 3 version and connecting to maven 2 repo (repo.maven.apache.org).

Would be great if some one can suggest on what is wrong with my system?

Answer 1

I had this same issue and just like the comments suggested it was the maven proxy. Setup in \conf\settings.xml
