Windows

1) In the Command Prompt window, get the first exercise...

C:\Users\johndoe> exercism fetch java

New:
java (Etl)      C:\Users\johndoe\exercism\java\etl

unchanged: 0, updated: 0, new: 1

2) In the "Welcome to IntelliJ IDEA" window, click the "Open" option.

3) Navigate to the "C:\Users\johndoe\exercism\java\etl" folder. Make sure you've selected the "etl" folder. Click "OK".

4) In the "Import Project from Gradle" dialog, check the "auto-import" and "create directories" checkboxes and select "Use customizable gradle wrapper".

Gradle project:    [C:\Users\johndoe\exercism\java\etl\build.gradle   ](...)

[X] Use auto-import
[X] Create directories for empty content roots automatically

( ) Use default gradle wrapper (not configured for the current project)
(o) Use customizable gradle wrapper
( ) Use local gradle distribution

...

5) Click "OK". IntelliJ will automatically create its project artifacts based on the Gradle project file.

• After the project has loaded and you've dismissed the "Tip of the Day" dialog, you may see a notice (in the top-right-hand corner), saying, "Unindex remote maven repositories found." you can safely dismiss this notice.

6) Open the README.md file and carefully read the background for the assignment.

7) Start by running the test suite: In the "Project" view, right-click on the test file (etl\src\test\java\EtlTest), select "Run", then pick the "EtlTest" that has a JUnit icon to the left of it (red and green arrows), NOT the Gradle icon (circular green).

• When you first start an exercise, you should expect compilation errors because the test is setting expectations on a class that you need to write. By trying to run the tests, you get a nice list of what needs to be fixed in the "Messages Make" view.

... and away you go!!!

Mac OS X

Get started with the first exercise

1. In the terminal window, get the first exercise...

   $ exercism fetch java
   
   Not Submitted:       1 problem
   Java (Etl) /Users/johndoe/exercism/java/etl
   
   New:                 1 problem
   Java (Etl) /Users/johndoe/exercism/java/etl
   
   unchanged: 0, updated: 0, new: 1
   

2. In the "Welcome to IntelliJ IDEA" window, click the "Open" option.

3. Navigate to the /Users/johndoe/exercism/java/etl folder. Make sure you've selected the "etl" folder. Click "OK".

4. In the "Import Project from Gradle" dialog, check the "auto-import" and "create directories" checkboxes and select "Use customizable gradle wrapper".

   • If these menu options don't appear at first, wait for a few seconds and try again; IntelliJ is still configuring the project with a Java nature.

   • When you first start an exercise, you should expect compilation errors because the test is setting expectations on a class that you need to write. By trying to run the tests, you get a nice list of what needs to be fixed in the "Messages Make" view.
