An example for both Java and Kotlin of how to use Autumn di container

Autumn Examples

This project contains four sub projects demonstrating the usage of Autumn DI contaier project in different situations, such as it's usage with Java, Kotlin, more complex scenarios such as mutli projects builds with Gradle as well as execeptional cases such as finding circular dependencies.

Obersevations

All projects make use of gradle shadow plugin to be packaged into a uber jar file, still, there are some considerations to keep in mind:

• All members of multi-project build must apply the shadow plugin through a custom precompiled plugin
• Kotlin projects are uncapable of loading classes through reflection as long as Meta-INF/version/9/module-info.class is present in your uber jar, therefore this file must be excluded from the resulting jar by configuring ShadowJar task under build.gradle.kts file as follows:

tasks.withType<ShadowJar>().configureEach {
    exclude("Meta-INF/version/9/module-info.class")
}

How to build and run

You can run all projects as an application with gradle runcommand, but multi-project, this one expects to be ran by a sub project containing an entry point (psvm), in this case app sub project by using gradle :app:run command.

In order to convert each project into a uber file run gradle shadowJar, the resulting jar will be located at current path/build/libs/projectname-version-all.jar, as expected multi-project needs to packaged from app sub project with the following command gradle :app:shadowJar, the resulting jar will be found at current path/app/build/libs/app-0.0.1-all.jar
