Welcome to the world of microservices with Helidon, an innovative set of Java libraries designed specifically for building robust microservices. If you’re looking to enhance your Java applications, this guide will walk you through getting started with Helidon and troubleshooting common issues along the way.

Understanding Helidon

Helidon comes in two programming models:

• Helidon MP: This model follows the MicroProfile 6.0 specification for microservices.
• Helidon SE: This functional style API focuses on simplicity and efficiency.

Both models allow your application to run as a Java SE program on the new Helidon Níma WebServer, utilizing Java 21’s Virtual Threads for improved performance. Think of it as having a highly efficient robot that can handle multiple tasks at once, making it faster and easier to work with.

Installing Helidon

Below are the installation steps for different operating systems:

For macOS:

curl -O https://helidon.io/cli/latest/darwin/helidon
chmod +x helidon
sudo mv helidon /usr/local/bin

For Linux:

curl -O https://helidon.io/cli/latest/linux/helidon
chmod +x helidon
sudo mv helidon /usr/local/bin

For Windows:

PowerShell -Command Invoke-WebRequest -Uri https://helidon.io/cli/latest/windows/helidon.exe -OutFile C:\Windows\system32\helidon.exe

Building Your Application

Make sure you have JDK 21 and Maven (version 3.8.0 or newer) installed on your machine. To build your Helidon application, follow these steps:

mvn install

To check code style and copyright compliance, use these commands within your project directory:

mvn validate -Pcheckstyle

mvn validate -Pcopyright

mvn verify -Pspotbugs

Troubleshooting Common Issues

While getting started with Helidon, you may encounter some roadblocks. Here are some troubleshooting tips:

• Java Version Error: Ensure you are using JDK 21, as Helidon 4 requires it.
• Maven Issues: If you have older versions, upgrade Maven to at least 3.8.0.
• Compatibility Problems: Check the Helidon SE Upgrade Guide to modify your code as needed.
