# Version 25 LTS
sudo apt install openjdk-25-jdk

Verifying Java installation

java -version

Gradle Configuration

Gradle is a build automation tool for our code that builds upon the contributions made by tools like Ant and Maven, but attempts to take it all a step further.

To start, it relies on Groovy and a DSL (Domain Specific Language) to work with a simple and clear language when constructing the build compared to Maven.

On the other hand, it has great flexibility that allows working with it using other languages and not just Java. In addition, it has a solid dependency management system.

• Available distributions: https://services.gradle.org/distributions/

Gradle runs on all major operating systems and only requires the installation of a Java JDK version 8 or higher.

  • Double-click the ZIP file to view the content.
  • Drag the content folder gradle-${version} to your newly created C:\Gradle folder.
  • Alternatively, you can unzip the Gradle distribution ZIP into C:\Gradle using a compression tool of your choice.
• Configure your system environment
  • In File Explorer, right-click on the This PC (or Computer) icon, then click on Properties -> Advanced system settings -> Environment Variables.
  • In System Variables select Path, then click Edit.
  • Add an entry for C:\Gradle\gradle-${version}\bin.
  • Click OK to save.

Linux

Linux is not officially supported at LATAM Airlines.

• Download the latest Gradle distribution.

  Example of the version to download

  version=9.2.1
  wget https://services.gradle.org/distributions/gradle-${version}-bin.zip

• Unzip the distribution

  Unzip the distribution zip file into the directory of your choice

  mkdir /opt/gradle
  unzip -d /opt/gradle gradle-${version}-bin.zip
  ln -s /opt/gradle/gradle-${version} /opt/gradle/latest

• Configure your system environment

  Create /etc/profile.d/gradle.sh with the following content:

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

  Give execution permissions to the script

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

Verify your installation:

Verifying Gradle installation

gradle -v

NodeJS

NodeJS is a cross-platform runtime environment for the server layer (server-side) based on JavaScript.

It is event-driven and was designed to build scalable applications, allowing you to establish and manage multiple connections at the same time. Thanks to this feature, you don't have to worry about process blocking, as there are no locks.

Windows

note

First you need to install Windows Subsystem for Linux (WSL).

Follow the instructions at https://docs.microsoft.com/en-us/windows/wsl/install

• Download the Installer:
  • Open your web browser and go to the official Node.js website.
  • The website offers two versions: the LTS (Long-Term Support) version (recommended for most users due to its stability) and the Current version (for the latest features).
  • Click the button to download the Windows Installer (.msi) for the recommended LTS version. The site should automatically detect if you need the 64-bit or 32-bit version.
• Run the Installer:
  • Locate the downloaded .msi file and double-click it to start the Node.js Setup Wizard.
  • If a security prompt appears, click Yes to allow the app to make changes to your device.
• Follow the Setup Wizard:
  • Click Next on the welcome screen.
  • Read and accept the license agreement by checking the box, then click Next.
  • Choose the installation destination folder (the default location is usually fine) and click Next.
  • On the "Custom Setup" screen, ensure that "Add to PATH" is selected, as this allows you to run Node.js commands from any terminal window.
  • Click Next. You can optionally choose to install necessary tools for native modules on the next screen, which may require Python and Visual Studio build tools, but this is not essential for basic use and can be skipped or installed later.
  • Click Install to begin the installation process.
• Finish the Installation:
  • Once the installation is complete, click Finish to exit the setup wizard

Linux
