1. Installing Java JDK 17 On Your Machine

Ensure that you do not have younger or older versions of Java JDK on your machine. If you do, you will need to uninstall or setup your paths correctly.

You can check if you have a previous version of Java installed by opening a terminal and running the following command:

java --version

1.1. Adoptium Java JDK 17 Installation

Navigate to Latest Releases | Adoptium in your browser, and download the .msi file for your architecture and Windows OS.

Open the .msi file you downloaded and follow the prompts to install Java.

You can verify the installation succeeded by checking the version using the command:

You may need to close all terminals you have open, and open a new one for the command to work

java --version

The output should look like the following (doesn’t need to be identical. Most importantly needs to show Java 17)

openjdk 17.0.9 2023-10-17
OpenJDK Runtime Environment Temurin-17.0.9+9 (build 17.0.9+9)
OpenJDK Client VM Temurin-17.0.9+9 (build 17.0.9+9, mixed mode, emulated-client)

2. Gradle 8.8 Installation

1. Download the Gradle zip file from here.
2. Create a new directory C:\Gradle with File Explorer.

You can choose to pick a different directory. In this case, replace all instances of C:\Gradle with your chosen directory.

3. Unzip the contents of the Gradle zip file and copy the contents of the gradle-8.8 folder into the directory C:\Gradle

C:\Gradle folder contents after Step 3

4. Search and open up Edit the system environment variables. There are two very similar options. Ensure you pick the matching name (highlighted red in the image below).

5. Click on Environment Variables. This should open another pop-up.

6. Under System variables, select Path and click Edit.

7. Click New and add a new entry called C:\Gradle\bin. Then click OK to close the current pop-up, and OK again to close the Environment Variables pop-up.

8. Close all open terminals.
9. Verify installation by opening a terminal (Powershell or Command Prompt) and running:

gradle --version

The following output is expected:

------------------------------------------------------------
Gradle 8.8
