Comprehensive Guide to Packaging Jooby Applications

Jooby is a powerful microframework for building web applications in Java. This guide provides an overview of how to effectively package and deploy your Jooby applications, making it accessible for beginners and seasoned developers alike.

Key Concepts

• Packaging: The process of bundling your application and its dependencies into a format that can be easily distributed and run.
• Build Tools: Jooby supports popular build tools like Maven and Gradle for managing project dependencies and creating executable packages.

Packaging Methods

1. Using Maven

• Maven Configuration: Define your project in a pom.xml file, which specifies dependencies and plugins.
• Executable JAR: Create a self-contained JAR file that includes all necessary libraries using the maven-shade-plugin.

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <version>3.2.4</version>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

2. Using Gradle

• Gradle Configuration: Define your project in a build.gradle file.
• Shadow Plugin: Similar to Maven’s shade plugin, Gradle uses the Shadow plugin to create an executable JAR.

plugins {
    id 'com.github.johnrengelman.shadow' version '7.1.0'
}

shadowJar {
    archiveBaseName.set('my-jooby-app')
    archiveClassifier.set('')
    archiveVersion.set('0.1.0')
}

Running the Application

Once packaged, you can run your Jooby application using the following command:

java -jar my-jooby-app.jar

Conclusion

Packaging your Jooby application is essential for distribution and deployment. By utilizing tools like Maven or Gradle, you can easily bundle your application and all its dependencies into a single executable JAR file, simplifying the process of running your application in any compatible Java environment.
