• Dependencies
  • Special Lego blocks that other people made, which you need for your castle.

mvn clean package

1. Maven reads the pom.xml.
2. Downloads the dependencies.
3. Compiles your code.
4. Squishes it all into one runnable .jar file.
   • By default, Maven names the jar based on <artifactId> and <version>
   • Added <finalName>app</finalName> into the <build> section of the pom.xml to name the jar.
