Basics
The libraries that get dynamically loaded from the SimplixCore are jar files contained in the ./libraries folder. You can drop any jar file in here, its content will be accessible for all plugins.
Your application can depend on libraries. Click here for more information about that. Libraries that were downloaded automatically are placed in a subfolder of ./libraries named after your application. Please be aware that jar files placed in this directory are not loaded dynamically.
A SimplixLibrary is a library that is loaded as a SimplixApplication and therefore will be capable of using the dependency injection possibilities the SimplixCore brings. Also, normal applications can specify SimplixLibrary that needs to be loaded before the application starts up. SimplixLibraries are also capable of depending on each other.
