How To Install Gradle on AlmaLinux 9

Gradle is a powerful and flexible build automation tool that has become increasingly popular among developers for its ability to streamline the software development process. It offers a wide range of features and capabilities, making it an excellent choice for building, testing, and deploying software projects across various languages, including Java, C++, and Groovy. In this comprehensive guide, we will walk you through the step-by-step process of installing Gradle on AlmaLinux 9, ensuring that you have all the necessary tools and knowledge to leverage its full potential.

Prerequisites for Installing Gradle

Before diving into the installation process, it’s crucial to ensure that your AlmaLinux 9 system meets the necessary requirements. Gradle requires a compatible version of the Java Development Kit (JDK) to function properly. Additionally, having a clean and up-to-date AlmaLinux 9 installation is essential to avoid any potential conflicts or issues during the setup process. Make sure you have the following prerequisites in place:

• A running AlmaLinux 9 system with root or sudo access
• A compatible version of the Java Development Kit (JDK) installed
• An active internet connection to download the required packages

Step 1: Update AlmaLinux System

Before proceeding with the Gradle installation, it’s always a good practice to ensure that your AlmaLinux system is up to date. Updating the system helps to resolve any potential security vulnerabilities, bug fixes, and compatibility issues. To update your AlmaLinux 9 system, open a terminal and execute the following commands:

sudo dnf update
sudo dnf install epel-release

These commands will update the system packages to their latest versions and install the EPEL (Extra Packages for Enterprise Linux) repository, which provides additional packages that may be required for the Gradle installation.

Step 2: Install Java Development Kit (JDK)

Gradle relies on the Java Development Kit (JDK) to compile and run Java-based projects. If you don’t have a compatible JDK version installed on your AlmaLinux 9 system, you can easily install it using the following command:

sudo dnf install java-1.8.0-openjdk-devel

This command will install the OpenJDK 8 development kit, which is a widely used and supported version of Java. Once the installation is complete, you can verify the Java version by running:

java -version

The output should display the installed Java version, confirming that the JDK is properly set up on your system.

Step 3: Download Gradle

With the prerequisites in place, you can now proceed to download the latest version of Gradle. Visit the official Gradle releases page and copy the download link for the desired Gradle version. At the time of writing, the latest stable version is 8.10.

Open a terminal and use the wget command to download the Gradle distribution package:

wget https://services.gradle.org/distributions/gradle-8.10-bin.zip -P /tmp

This command will download the Gradle binary distribution package to the /tmp directory on your AlmaLinux 9 system.

Step 4: Install Gradle on AlmaLinux 9

With the Gradle distribution package downloaded, you can now extract its contents and set up the necessary environment variables. Follow these steps to install Gradle on your AlmaLinux 9 system:

1. Create a directory to store the Gradle installation files:

sudo mkdir /opt/gradle

2. Extract the downloaded Gradle package to the newly created directory:

sudo unzip -d /opt/gradle /tmp/gradle-8.10-bin.zip

This command will extract the contents of the Gradle package to the /opt/gradle directory.

3. Ensure that the extracted files have the appropriate permissions:

sudo chown -R root:root /opt/gradle/gradle-8.10

This command sets the ownership of the Gradle files to the root user and group, ensuring proper access control.

Step 5: Set Up Environment Variables

To make Gradle accessible from any directory on your AlmaLinux 9 system, you need to set up the necessary environment variables. Follow these steps:

1. Create a new file named gradle.sh in the /etc/profile.d directory:

sudo nano /etc/profile.d/gradle.sh

2. Add the following lines to the file:

export GRADLE_HOME=/opt/gradle/gradle-8.10
export PATH=${GRADLE_HOME}/bin:${PATH}

These lines set the GRADLE_HOME environment variable to the Gradle installation directory and add the Gradle bin directory to the system’s PATH.

3. Save the file and exit the text editor.

4. Make the script executable by running:

sudo chmod +x /etc/profile.d/gradle.sh

5. Load the environment variables by executing:

source /etc/profile.d/gradle.sh

Step 6: Verify Gradle Installation

To ensure that Gradle is installed correctly and accessible from any directory, you can run the following command:

gradle -v

If the installation was successful, you should see the Gradle version information displayed in the output, along with other relevant details.

Troubleshooting Common Issues

While installing Gradle on AlmaLinux 9 is generally a straightforward process, you may encounter some common issues. Here are a few troubleshooting tips to help you resolve them:

• Permission Denied Errors: If you encounter permission-related errors during the installation process, ensure that you have the necessary root or sudo privileges to execute the commands.
• Java Not Found: If Gradle fails to locate the Java installation, double-check that you have installed a compatible JDK version and that the JAVA_HOME environment variable is set correctly.
• Network Connectivity Issues: If you experience problems downloading the Gradle package, verify that your AlmaLinux 9 system has an active internet connection and that any firewall or proxy settings are properly configured.
