Jump

A very very basic and simple example Java project for teaching courses and as a quick start for examples.

Dev Environment

How to setup your dev environment to work with the course examples and exercises.

1. Java JDK 8:

   • Download and install from http://www.oracle.com/technetwork/java/javase/downloads

2. GIT (version 2.7 or higher)

   • Download and install from https://git-scm.com/downloads

   • Recommended tutorials for using GIT:

     • https://git-scm.com/doc
     • online version of the book https://git-scm.com/book

   • Initial Configuration (important!!):

     • personalize your GIT by setting your username and email for commits:

      > git config --global user.name "<your-username>"             
      > git config --global user.email <yourname>@<your-email-domain>.com
      ```
     
     see also here: https://git-scm.com/book/en/v2/Getting-Started-First-Time-Git-Setup
     
     

3. IntelliJ

   • latest version of IntelliJ IDEA Community Edition (this tutorial is based on version 15)
   • Download from https://www.jetbrains.com/idea/

4. Gradle

   • Gradle tooling is included as gradle wrapper allready 😄

5. Clone Source Repository from GIT:

   • Create a folder on your local disk, where you want to work with the example sources
   • Open command line (under Windows use the GIT Bash) inside this folder
   • type following git command:

   git clone https://github.com/bruderol/jump.git
   

   This needs to be done from command line, because IntelliJ can not import a gradle project directly from source control somehow

6. Open project in IntelliJ

   • File / New / Project from Existing Sources ...
   • Select the jump project folder that has been checked out to your directory
   • Select Import project from external model: - Gradle
   • Select Use default gradle wrapper and a JVM (the installed JDK 8)

7. Starting the application from IntelliJ

   • In Project Explorer: Browse to the Java Class JumpExampleApp (in src folder ...)
   • Select Run JumpExampleApp from context menu
   • See output in the run window console

8. Running the tests from IntelliJ:

   • Browse to src/test/java
   • Select Run All Tests from context menu
   • all tests should be passed and green (currently one)

Open points / Decissions

• Will we need to install Gradle or Maven?
  • I decided to go for gradle in the new setup (because cooler and more state of the art)
  • Gradle is included as a wrapper allready 😄
