Gradle is a free and open source build automation toolset based on the concepts of Apache Ant and Apache Maven. Gradle provides a platform to support the entire development lifecycle of a software project.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step installation Gradle on a 18.04 LTS (Bionic Beaver) server.
Install Gradle on Ubuntu 18.04 LTS
Step 1. First, make sure that all your system packages are up-to-date
sudo apt-get update sudo apt-get upgrade
Step 2. Installing Java.
Gradle requires Java to be installed on your server. By default, Java is not available in Ubuntu’s repository. Add the Oracle Java PPA to Apt with the following command:
add-apt-repository ppa:webupd8team/java apt-get update -y apt-get install oracle-java8-installer
Verify the Java version by running the following command:
java -version
Step 3. Download Gradle
Run the commands below to download Gradle, At the time of this writing, the version is 4.10.2:
wget https://services.gradle.org/distributions/gradle-4.10.2-bin.zip -P /tmp
Now extract downloaded archive using the following command:
sudo unzip -d /opt/gradle /tmp/gradle-*.zip
Step 4. Configure Ubuntu Environment Variables.
You can do that by running the commands below to create a new file called gradle.sh in the /etc/profile.d directory:
sudo nano /etc/profile.d/gradle.sh
Paste the following configuration:
export GRADLE_HOME=/opt/gradle/gradle-4.10.2
export PATH=${GRADLE_HOME}/bin:${PATH}
When you’re done, run the commands below to make the file executable:
sudo chmod +x /etc/profile.d/gradle.sh source /etc/profile.d/gradle.sh
Step 5. Verify the Gradle installation.
You can run the following command to check if the Gradle install was successful:
gradle -v
You should see the following output:
