Install gradle with SDKMAN!

The description how to install SDKMAN! can be found here with the following command:

If you have installed SDKMAN! you can now install gradle with the following command:

sdk install gradle 5.6.4

As next step you can check the gradle installation. Enter the following command:

gradle -v

Install manually

In order to install Gradle on ubuntu, you need sudo privileges.

• First you have to install the JDK. Install java jdk

• Download Gradle release in the user temp folder:

wget https://services.gradle.org/distributions/gradle-5.6.4-all.zip -P ~/tmp

Now we can extract the zip file in the /opt/gradle directory:

sudo unzip -d /opt/gradle ~/tmp/gradle-5.6.4-all.zip

Check that the Gradle files are extracted:

ls -al /opt/gradle/gradle-5.6.4

The output should look similar like the following:

drwxr-xr-x  9 root root   4096 Feb  1  1980 .
drwxr-xr-x  3 root root   4096 Jul 27 11:08 ..
drwxr-xr-x  2 root root   4096 Feb  1  1980 bin
drwxr-xr-x  5 root root   4096 Feb  1  1980 docs
-rw-r--r--  1 root root 163129 Feb  1  1980 getting-started.html
drwxr-xr-x  2 root root   4096 Feb  1  1980 init.d
drwxr-xr-x  3 root root   4096 Feb  1  1980 lib
-rw-r--r--  1 root root  55261 Feb  1  1980 LICENSE
drwxr-xr-x  2 root root   4096 Feb  1  1980 media
-rw-r--r--  1 root root    802 Feb  1  1980 NOTICE
drwxr-xr-x 45 root root   4096 Feb  1  1980 samples
drwxr-xr-x 86 root root   4096 Feb  1  1980 src

Set environment variable GRADLE_HOME and add to PATH

There are several options to set environment variables on Linux but the preferred option is to set it in the file 'etc/environment'

sudo awk 'BEGIN{ printf "GRADLE_HOME=\"/opt/gradle/gradle-5.5.1\"" >> "/etc/environment"  }'
source /etc/environment

Now we have to configure the PATH environment variable to include the Gradle bin directory. Therefore we create a new shell file named gradle.sh inside of the /etc/profile.d/ directory.

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

insert the following:

export PATH=${GRADLE_HOME}/bin:${PATH}

write and quit with :wq!. The gradle.sh will be sourced by the next shell start.

Now we have to make the gradle.sh executable with the following command:

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

Verify the gradle installation

To verify that the installation has been successful we can execute the following command:

gradle -v

The output should look similar to the following:
