How to install Gradle on Ubuntu 22.04.
Prerequisites:
- A Ubuntu 22.04 installed dedicated server or KVM VPS.
- A root user access or normal user with sudo privileges.
1. Keep the server up to date
sudo apt update && sudo apt-get upgrade -y
2. Install required package
sudo apt install unzip -y
3. Install OpenJDK
Here, we're installing default OpenJDK 11, which is already included but this will not be the latest version. For Gradle we required OpenJDK 8 and later.
If your project require latest version or specific version of JDK, please refer official documentation. Execute following command:
sudo apt install default-jdk
Verify the Java installation by printing the Java version :
java -version
4. Download Gradle
At the time of writing this article, the latest version of Gradle is v8.1.1. Before continuing with the next step, you should check the Gradle releases page to see if a newer version is available.
Download the Gradle binary file in the /tmp directory using the following wget command:
wget https://services.gradle.org/distributions/gradle-8.1.1-bin.zip -P /tmp
Once the download is completed, unzip the file in the /opt/gradle directory:
sudo unzip -d /opt/gradle /tmp/gradle-*.zip
5. Configure the environment variables
Next, we'll create one file named gradle.sh to configure the environmental variable PATH. Create a file in the /etc/profile.d directory. Use your favorite editor. For this demonstration purpose, we are using nano editor.
sudo nano /etc/profile.d/gradle.sh
Paste the following configuration:
export GRADLE_HOME=/opt/gradle/gradle-8.1.1
export PATH=${GRADLE_HOME}/bin:${PATH}
Note: Replace gradle-gradle-8.1.1 with the version of your gradle.
Save and exit.
Next, make the script executable by using chmod command like shown below:
sudo chmod +x /etc/profile.d/gradle.sh
Load the environment variables using the source command :
sudo source /etc/profile.d/gradle.sh
Above command may not work if you are a normal user with sudo privileges. Please find some way to execute the command or ask you root user to execute this command.
To validate that Gradle is installed properly run the following command which will display the Gradle version:
gradle -v
Output will be similar like:
Welcome to Gradle 8.1.1!
Here are the highlights of this release:
- Stable configuration cache
- Experimental Kotlin DSL assignment syntax
- Building with Java 20
