To build a Maven project you would probably use the "package" goal. That will compile the source code into class files and package those class files into a JAR/WAR. The install will do all that, but will also then copy that packaged file to the local Maven repository, usually a directory called ".m2" in your user directory or a root directory.

For more info on this and other goals see https://maven.apache.org/guides/introduction/introduction-to-the-lifecycle.html

how .m2 in user directory and root directory are related or different?
