Do I need to set pom.xml by myself? How and where? Did I install Maven correctly in Windows?
The command to find the version of maven is
mvn -X -version

do I need to set pom.xml by myself? How and where?
You create a pom.xml within a maven based project at the top level directory. The first maven project sample shall help you further here.
