Quarkus Native

In this tutorial, you'll learn about Fix Quarkus Native Image Build Fails. We cover key concepts, practical examples, and best practices.

The Problem

Quarkus native image build fails with reflection or serialization errors.

Quick Fix

Build with -Pnative

Wrong:

mvn package // Not native

Output:

Regular JAR built

Right:

mvn package -Pnative -DskipTests
# Requires GraalVM and native-image tool

Output:

Native binary built

Add @RegisterForReflection

Wrong:

// No reflection registration
public class Product { }

Output:

Reflective access fails

Right:

@RegisterForReflection
public class Product {
    public String name;
    public BigDecimal price;
}

Output:

Reflection registered

Configure Quarkus Maven plugin

Wrong:

<!-- No native profile -->
<plugin>
    <groupId>io.quarkus.platform</groupId>
    <artifactId>quarkus-maven-plugin</artifactId>
</plugin>

Output:

Build fails

Right:

<plugin>
    <groupId>io.quarkus.platform</groupId>
    <artifactId>quarkus-maven-plugin</artifactId>
    <executions>
        <execution>
            <goals><goal>build</goal></goals>
        </execution>
    </executions>
</plugin>

Output:

Plugin configured

Prevention

• Use -Pnative Maven profile or quarkusBuild Gradle task
• Add @RegisterForReflection for classes accessed via reflection
• Install GraalVM and native-image tool

Common Mistakes with native

1. Mixing let bindings with <- bindings in do notation, producing type errors
2. Overlapping type class instances that cause GHC to reject the program with ambiguous dispatch errors
3. Non-exhaustive pattern matches that compile with warnings then crash at runtime

These mistakes appear frequently in real-world QUARKUS code. DodaTech's contributors have identified these patterns through analysis of open-source projects and production systems.

Practice Exercise

Write a pure function that safely divides two integers using Maybe, then test it with edge cases like division by zero and negative numbers.

This exercise reinforces the concepts covered in this guide. Try implementing it before checking online solutions.
