How to Install Gradle on Ubuntu 18.04 ? :

Through this blog it is demonstrated the Gradle 4.10.2! installation on Ubuntu 18.04 VM.

At the end of this blog the Installation video clip is attached.


Step#1: Install OpenJDK:

Gradle needs Java JDK or JRE version 7 or
above to be installed.
We will install OpenJDK 8 as below.
Let us update the linux package index.

sudo apt update

Install the OpenJDK package with the below command:

Install the OpenJDK package.

sudo apt install openjdk-8-jdk
Check the java version.

Java -version

Step#2: Download Gradle

Using the below command; Used the below valid command…..

wget -P /tmp
Once the download is completed, we need to extract the zip file into folder; /opt/gradle :

sudo unzip -d /opt/gradle /tmp/gradle-*.zip

let us Verify that the Gradle files are extracted by listing the /opt/gradle/gradle-4.10.2 directory
ls /opt/gradle/gradle-4.10.2

The typical file list will be:

bin getting-started.html init.d lib LICENSE media NOTICE

Step#3: Setting up environment variables:

Now, we need to configure the PATH environment variable to include the Gradle bin directory.
To do this task; need to open a text editor and create a new file named inside of the folder; /etc/profile.d/

sudo vim /etc/profile.d/

In this shell program [config file] paste the below lines;

export GRADLE_HOME=/opt/gradle/gradle-4.10.2
export PATH=${GRADLE_HOME}/bin:${PATH}

The above script will be initiated at startup.

Now, let us Load the environment variables using the following command;

source /etc/profile.d/

Step#4: Verify the Gradle installation

To validate the installation of Gradle
use the command;

gradle -v

It will display the Gradle version.

So the Gradle is installed successfully.
