Install Java SE

Now, you need to have Java Standard Edition (SE) on your Debian 10 system. This can be done by entering the following command in Terminal and then pressing the Enter key :

sudo apt install default-jdk

During the process of handling this command, your Debian 10 system needs to be sure that you are really ready to install the command. You can type 'Y' and then press the Enter key if you are sure to continue with the Java SE installation:

Up to now, Java SE has been successfully installed on your Debian 10 system. If you want to verify that it is actually installed, then you can do so with the help of the following command:

java -version

Successful execution of this command will result in the Java SE version displayed.

Download Gradle binaries

The next step is to download Gradle binaries on a Debian 10 system. This can be done by entering the following command in Terminal and then pressing the Enter key :

wget https://services.gradle.org/distributions/gradle-6.3-bin.zip -P /tmp

If you get the error message running this command, then the wget command is most likely not activated on a Debian 10 system. Wget can be activated by typing the following command and pressing the Enter key :

sudo apt-get install wget

Once the wget command is successfully installed, you can conveniently run the above command. Once Gradle has been successfully downloaded on a Debian 10 system, you should see the results displayed in the Terminal:

Extract the Gradle file

Since the Gradle file you just downloaded is in binary format, the next thing to do is unzip it. This can be done simply with the help of the following command:

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

Running this command will extract the files from the tmp directory and save them in the opt directory . Now the Debian 10 system will do some processing, then the Terminal window will look like this:

To verify if the extraction was performed successfully, you can try to display the contents of the extracted folder with the help of the following command:

ls /opt/gradle/gradle-*

If the Gradle files have been successfully extracted, you should be able to see them in Terminal.

Set environment variables

Now, you need to set the environment variables by creating a new file called gradle.sh with the help of the following command:

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

After creating this file, add the content shown in the following image to the newly created file. Then save the file and close it.

Now, you need to make this newly created file executable by running the following command:

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

Next, run the following command in Terminal to load the newly set environment variables:

source /etc/profile.d/gradle.sh

Gradle has now been successfully installed on your Debian 10 system.

To verify that, simply enter the following command in Terminal, then press the Enter key :

gradle -v

Gradle has been successfully installed on your Debian 10 system!
