I see nothing wrong with the image you posted, looks like a typical Maven directory structure. If you expand src you should see src/main/webapp. And there is never a lib directory in a Maven project (not even at src/main/webapp/WEB-INF/lib, and don't try to put one there either!)
Your question leads me to suspect that you have not worked with Maven before. If that is true, you should spent some time reading about Maven or else you will just get frustrated (and make lots of mistakes because you will make lots of invalid assumptions).
If you have Eclipse IAM installed, deinstall it. The POM icon in your screenshot looks like the one used by IAM. Nothing personal against it, but having two Maven integrations installed parallel will certainly confuse.
