Clean Code & Refactoring

Requirements

• Maven: https://maven.apache.org/
• Java: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
• IntelliJ Community Edition: https://www.jetbrains.com/idea/#chooseYourEdition
• Git: https://git-scm.com/

Please try to create and build a hello world project in IntelliJ using Maven before the workshop! The less time spent fixing Java paths and SDK versions the better.

How to run code with Maven

Ensure that:

• Maven is on your PATH (typing mvn --version in a terminal should not produce an error)
• If Maven is not on your PATH, you have to add it.
  • Windows: Control Panel -> Search "environment variables" -> "Edit environment variables for your account" -> find the PATH variable -> In the Value field add the directory where your mvn.exe is located

With Maven ready, you can either run it from a terminal:

• Open a terminal and navigate to where the project's POM.xml file is located
• mvn compile
• mvn test

Or you can run it from within IntelliJ:

• In IntelliJ, open the folder where the POM.xml is located as a project
• Run from the Run menu
