sudo apt install openjdk-11-jdk

Verify your Java installation by checking its version:

java -version

mkdir /opt/gradle

Next, unzip your downloaded file in the Gradle directory:

At this point, you need to add the Gradle bin directory to the system PATH environment variable. To do this, create a new file with your favorite text editor inside of the /etc/profile.d/ directory:

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

Add the following content to the file:

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

When you are done, save and close the file.

Now make your file executable:

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

Load the environment variables in the current shell session using the source command

source /etc/profile.d/gradle.sh

At this point, you can verify your Gradle installation on Ubuntu 20.04 by checking its version:

gradle -v
