3. • Micronaut is focused on modern
   architectures like Serverless and
   Microservices
   • Also a complete framework for any type of
   application
   • Lightweight, reactive (HTTP Client/Server
   based on Netty)
   • Annotation processor to compute framework
   infrastructure at compile time

6. Micronaut releases
   Copyright © 2022, Oracle and/or its affiliates
   • Core version drives a “Micronaut release”
   • Micronaut Core BOM includes many
   Micronaut modules
   • Gradle and Maven plugin integrate with the
   BOM

   • Micronaut Project Template
   
   Used to create new modules
   
   Defines project “template”
   
   Defines files to be sync’ed on all projects
   
   Shared configuration (checkstyle rules, ...)

10. Micronaut Build
    Copyright © 2022, Oracle and/or its affiliates
    • An internal plugin suite
    • Models how Micronaut modules are built
    • Configures common behavior
    
    Quality checks
    
    Sonar
    
    Publication to Maven Central
    
    Build cache
    
    Test selection
    
    ...

11. Gradle “convention plugins”
    Copyright © 2022, Oracle and/or its affiliates
    • For Maven users, think of “composite parent POMs”
    • Take care of shared configuration, aka conventions
    • Different plugins
    
    From Micronaut Build Plugins (internal)
     io.micronaut.build.internal.module : typical Micronaut module, with annotation
    processing enabled, published on Maven Central, etc.
     io.micronaut.build.internal.bom: a “platform”, or BOM for Maven

    Root project:
    plugins {
    id("io.micronaut.build.internal.docs")
    id("io.micronaut.build.internal.quality-reporting")
    }
    Module:
    plugins {
    id("io.micronaut.build.internal.aot-project")

    plugins {
    id "io.micronaut.build.internal.base-module"
    }

16. Gradle task wiring
    Copyright © 2022, Oracle and/or its affiliates
    • Forget about Maven lifecycle
    • In Gradle, lifecycle is dynamic
    A task
    (compileJava, test, ...)
    inputs

25. What about users?
    Copyright © 2022, Oracle and/or its affiliates
    • Gradle plugins are designed with the same composition model in mind
    ● io.micronaut.application = micronaut + application + docker + GraalVM
    ● io.micronaut.library = micronaut + library + docker + GraalVM
    ● io.micronaut.minimal.application = micronaut + application
    ● io.micronaut.minimal.library = micronaut + library
    • Declarative as much as possible
