Modules

Core: JSR-330:

• Core holds the demo project, a weather forecast command line application.
• Core-Avaje is a modified version of Core that specifies the avaje-inject-generator processor in the pom.xml.

Core: Custom annotations:

• Core-HK2 is a modified version of Core that specifies the hk2-metadata-generator processor in the pom.xml, and uses @Service/@Contract from HK2.
• Core-Inverno is a modified version of Core that specifies the inverno-core-compiler processor in the pom.xml, and uses @Bean from Inverno.

Implementations

• Impl-Avaje - Using Avaje-Inject framework to generate code for DI.
• Impl-Dagger - Using Dagger framework to generate code for DI.
• Impl-Dirk - Using Dirk to reflectively populate injected instances.
• Impl-Feather - Using Feather to reflectively populate injected instances.
• Impl-Guice - Using Guice to reflectively populate injected instances.
• Impl-HK2 - Using Glassfish HK2 to use a service-loader to discover and inject instances.
• Impl-Inverno - Using Inverno framework to generate code for DI from a module-info file.
• Impl-JayWire - Using JayWire to manually populate injected instances.
• Impl-JBock - Using JBock to generate code for DI, with mostly pre-defined existing module implementation.
• Impl-Spring - Using Spring Boot to reflectively populate injected instances.
• Impl-Weld - Using Weld to reflectively populate injected instances.
