Gradle is an open-source tool for build automation Java, Groovy, and Scala development. It relies on the concepts of Ant and Maven to automate the building process.
Unlike Apache Maven which relies on XML data files for declaring project configurations, Gradle uses Groovy, a dynamic programming language that defines project configurations.
In this post, we will install Gradle on Debian 11 / Debian 10.
Install JDK
Gradle’s only requirement is Java JDK version 8 or higher. So, install either OpenJDK or Oracle JDK.
Here, for the demo, we will use OpenJDK v11.
sudo apt update sudo apt install -y default-jdk
Verify the Java installation by executing the following command.
java -version
Output:
openjdk version "11.0.12" 2021-07-20 OpenJDK Runtime Environment (build 11.0.12+7-post-Debian-2) OpenJDK 64-Bit Server VM (build 11.0.12+7-post-Debian-2, mixed mode, sharing)
Install other required packages.
sudo apt install -y curl unzip
Install Gradle
Download the latest version of the Gradle (v7.2) – Binary-only zip file from the official site.
OR
Use the below command in the terminal to download the Gradle (v7.2) package.
cd /tmp curl -O https://downloads.gradle-dn.com/distributions/gradle-7.2-bin.zip
Then, extract the package using the unzip command.
unzip gradle-*.zip
Move the contents to /opt/gradle directory.
sudo mkdir /opt/gradle sudo cp -pr gradle-*/* /opt/gradle
Verify the Gradle’s directory.
ls /opt/gradle/
Output:
bin init.d lib LICENSE NOTICE README
Configure System Environment
We will now configure the PATH environment variable to include Gradle’s bin directory. To do that, execute the below command. If needed, replace the Gradle’s bin path with your Gradle’s directory.
echo "export PATH=/opt/gradle/bin:${PATH}" | sudo tee /etc/profile.d/gradle.sh
Make the script executable with chmod command.
sudo chmod +x /etc/profile.d/gradle.sh
Load the environment variables onto your current session by running the following command.
source /etc/profile.d/gradle.sh
Verify Gradle installation
To validate the Gradle installation, use the below command.
gradle -v
Output:
