The default type of artifact generated by Maven is JAR. If the
packaging element is absent, or specified as
jar, Maven considers it a JAR project. A JAR project combines all the source classes along with the necessary project resources to a single file. This JAR file can be distributed for it to be used elsewhere.
Maven is set up on your system and is verified for work. To do this, refer to Chapter 1, Getting Started.
