Java Development Setup for VS Code

This guide will help you set up a complete Java development environment in Visual Studio Code without using containers.

Prerequisites

Before you begin, make sure you have the following installed on your machine:

1. Java Development Kit (JDK)

Install one or more JDK versions. We recommend installing LTS (Long-Term Support) versions:

• Java 11 (LTS)
• Java 17 (LTS)
• Java 21 (LTS - Recommended)

Installation by Operating System

Windows:

• Download from Oracle or Adoptium
• Install to default location: C:\Program Files\Java\jdk-21

macOS:

# Using Homebrew
brew install openjdk@21

# Or download from Oracle/Adoptium

Default location: /Library/Java/JavaVirtualMachines/jdk-21.jdk/Contents/Home

Linux:

# Ubuntu/Debian
sudo apt update
sudo apt install openjdk-21-jdk

# Fedora/RHEL
sudo dnf install java-21-openjdk-devel

Default location: /usr/lib/jvm/java-21-openjdk

2. Build Tools (Optional but Recommended)

Maven:

# Windows (using Chocolatey)
choco install maven

# macOS
brew install maven

# Linux (Ubuntu/Debian)
sudo apt install maven

Gradle:

# Windows (using Chocolatey)
choco install gradle

# macOS
brew install gradle

# Linux (Ubuntu/Debian)
sudo apt install gradle

3. Visual Studio Code

Download and install VS Code from code.visualstudio.com

Setup Instructions

Step 1: Install VS Code Extensions

Open VS Code and install the following extensions. You can do this by:

1. Opening the Extensions view (Ctrl+Shift+X or Cmd+Shift+X)
2. Searching for each extension by name
3. Clicking "Install"

Essential Extensions:

• Extension Pack for Java (vscjava.vscode-java-pack) - Includes all core Java extensions
• Language Support for Java (redhat.java) - Java language server
• Debugger for Java (vscjava.vscode-java-debug) - Debugging support
• Test Runner for Java (vscjava.vscode-java-test) - Run and debug tests
• Maven for Java (vscjava.vscode-maven) - Maven integration
• Gradle for Java (vscjava.vscode-gradle) - Gradle integration

Recommended Extensions:

• Spring Boot Extension Pack (vmware.vscode-spring-boot) - If using Spring Boot
• SonarLint (sonarsource.sonarlint-vscode) - Code quality analysis
• Checkstyle (shengchen.vscode-checkstyle) - Java code style checking
• IntelliCode (visualstudioexptteam.vscodeintellicode) - AI-assisted coding
• GitHub Copilot (github.copilot) - AI pair programmer
• GitLens (eamodio.gitlens) - Enhanced Git integration

Step 2: Create Project Configuration

In your Java project root, create a .vscode folder with the configuration files:

your-project/
├── .vscode/
│   ├── settings.json
│   ├── extensions.json
│   └── launch.json
├── src/
└── pom.xml (or build.gradle)

Copy the provided configuration files into the .vscode folder.

Step 3: Update Java Runtime Paths

Open .vscode/settings.json and update the java.configuration.runtimes section with your actual JDK installation paths.

Find your Java installation path:

# Windows (PowerShell)
where java

# macOS/Linux
which java
readlink -f $(which java)

Update the settings:

Replace the paths in

Note: I used a - instead of / since the gist won't allow the / character
