Double-click the file you downloaded, you should see the following interface

Java(TM) Installing Program

Click NEXT, and choose where you want to install it. Then you wait for it to finish installing and click CLOSE.

Verify JavaSDK (Optional)

You should now find your JavaSDK installation directory e.g. C:\Program Files\Java\jdk-19\bin and copy that path.

Download and Install IDE (Eclipse or IntelliJ)

The course will use Eclipse in its teaching material but all the things we do in the course can be done in IntelliJ too. You can download the latest version of Eclipse and IntelliJ (Community Edition) here.

Download and Install the Cucumber plugin

Eclipse

From the Eclipse marketplace (from inside the Help menu of Eclipse), download the "Cucumber" plugin.

Install Cucumber (Eclipse)

IntelliJ

IntelliJ already comes with a Cucumber plugin. But I recommend you also download a plugin called Cucumber for Java since it can add support for Cucumber testing tools with step definitions written. You can download that from File -> Settings -> plugins. 

Install Cucumber (IntelliJ)

Restart your IDE

After you install the Cucumber plugin, you need to restart your IDE (Your IDE will also notify you to do that).

Download and Import the project "libaray01" to your IDE

You can download the zip file library01.zip here. And then you should unpack the zip file first.

Eclipse

You can now import the project into Eclipse by clicking File -> Import Project -> General -> Projects from Folder or Archive. And then you click the Directory and choose the file you unpacked from the zip file. Then you mark that project library01 and click Finish.

Import project (Eclipse)

IntelliJ

You can now import the project into Eclipse by clicking Open and Choosing the file you unpacked from the zip file. Then click OK and Trust Project.

Import project (IntelliJ)

Click now Load button on the bottom right of the IDE. The Maven script will then be loaded and you can now wait for the project to be built.

Load Maven script

Run the project in your IDE

Eclipse

Find the file AcceptanceTest.java under the src/test/java/dtu.library.acceptance_tests and then right-click -> Run as -> JUnit Test. You will see the following content:

Run the project in Eclipse

Although the program fails the test (as it should), it proves that you can already run the cucumber plugin. You can now begin to implement the production code such that the scenarios "Admin login", "Admin logout", "Add book", and "Search book" pass.

IntelliJ

Find the file AcceptanceTest.java under the src/test/java/dtu.library/acceptance_tests and then right-click -> Run 'AcceptanceTest'. You will see the following content:
