How to set up a Java project on Linux?

Gradle

Gradle is a powerful and flexible build automation tool primarily used in software development to manage and automate the build processes of projects. It is often used for building, testing, and distributing software applications and libraries. Gradle is designed to handle projects of various sizes and complexities and is particularly well-suited for large-scale and multi-module projects.

Let's install the Java package:

 sudo apt install default-jdk -y 

Test installation:

java --version

Let's download Gradle package:

wget -c https://services.gradle.org/distributions/gradle-8.3-bin.zip -P /tmp

...and unzip into /opt directory:

sudo unzip -d /opt/gradle /tmp/gradle-8.3-bin.zip

We must setup ENV:

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

Where we add into file:

export GRADLE_HOME=/opt/gradle/gradle-8.3
export PATH=${GRADLE_HOME}/bin:${PATH}

WE MUST RESTART SYSTEM!

Project

Let's prepare project:

mkdir mojProjekt
cd ./mojProjekt

gradle init

The command gradle init is used to initialize (set up) a new project or module in Gradle. This command helps create the basic structure of the project, including configuration files and other resources needed for building and managing the project. Okay, now we can see whole structre with "tree" command: We open "App.java" in text editor: Project is compiled with:

 gradle build

And finally, run:

gradle run

Happy coding!
