Installing and setting up Gradle is the first step to leverage its powerful build automation capabilities. In this tutorial, we will guide you through the process of installing Gradle and configuring it for your projects.

Installation Steps

1. Prerequisites

Before installing Gradle, ensure that you have Java Development Kit (JDK) installed on your system. Gradle requires JDK 8 or higher to run. You can check your Java version by running the following command in a terminal or command prompt:

java -version

2. Download Gradle

Visit the official Gradle website at https://gradle.org/ and navigate to the "Downloads" section. Download the latest stable release of Gradle as a ZIP or binary distribution.

3. Extract the Distribution

Once the Gradle distribution is downloaded, extract it to a directory of your choice. This directory will be referred to as the "Gradle installation directory" in the following steps.

4. Set Environment Variables

To use Gradle from any location on your system, you need to set the `PATH` environment variable. Add the Gradle `bin` directory to your `PATH` variable. The specific steps vary depending on your operating system:

• Windows: Open the System Properties dialog, go to the "Advanced" tab, click the "Environment Variables" button, and edit the `PATH` variable to include the Gradle `bin` directory.
• macOS and Linux: Open a terminal and edit the `.bash_profile` or `.bashrc` file in your home directory. Add the following line to the file:

export PATH=$PATH:/path/to/gradle/bin

Replace `/path/to/gradle` with the actual path to your Gradle installation directory.

5. Verify the Installation

To verify that Gradle is correctly installed, open a new terminal or command prompt and run the following command:

gradle --version

If Gradle is installed properly, you should see the Gradle version and other details displayed in the output.

Common Mistakes to Avoid

• Not having JDK installed or using an incompatible version
• Forgetting to set the `PATH` environment variable after installing Gradle
• Using an incorrect path to the Gradle installation directory
