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.
In this tutorial, we will install the latest version of Gradle on Ubuntu 16.10.
A Vultr Ubuntu 16.10 server instance.
A sudo user.
Before installing any packages on your Ubuntu server instance, it is recommended to update the system. Login using the sudo user and run the following commands to update the system.
sudo apt-get update
sudo apt-get -y upgrade
Gradle requires Java Development Kit (JDK) 7 or higher in order to work. In this tutorial we will be installing JDK 8. Run the following command to install JDK 8 on your server.
sudo apt-get -y install openjdk-8-jdk wget unzip
The above command will also install wget and unzip. Verify the installation.
java -version
You will see the following output.
openjdk version "1.8.0_121"
OpenJDK Runtime Environment (build 1.8.0_121-8u121-b13-0ubuntu1.16.10.2-b13)
OpenJDK 64-Bit Server VM (build 25.121-b13, mixed mode)
Gradle distribution archive comes in two types: "binary-only" and "complete". The "binary-only" archive contains the Gradle software only wheres "complete" archive comes with binary, documentation and source. Run the following command to download Gradle to your system.
wget https://services.gradle.org/distributions/gradle-3.4.1-bin.zip
You can always check the Gradle release page to look for the link to the latest version of Gradle.
Create a directory for the Gradle installation.
sudo mkdir /opt/gradle
Extract the downloaded archive to the newly created directory.
sudo unzip -d /opt/gradle gradle-3.4.1-bin.zip
Configure the PATH environment variable so that the gradle executable can be directly executed anywhere on the system.
export PATH=$PATH:/opt/gradle/gradle-3.4.1/bin
You can run the following command to check if the Gradle install was successful.
gradle -v
You should see the following output.
