is technically possible, however you would still have to create an instance of the event listener to register it at an event bus.
## Installation
Event Bus is available in Maven Central.
To include it inside your project, just add the following dependency to your `pom.xml`:
```xml
<dependencies>
<dependency>
<groupId>dev.kske</groupId>
<artifactId>event-bus-core</artifactId>
<version>1.1.0</version>
</dependency>
</dependencies>
```
Then, require the Event Bus Core module in your `module-info.java`:
```java
requires dev.kske.eventbus.core;
```
If you intend to use event handlers that are inaccessible to Event Bus by means of Java language access control, make sure to allow reflective access from your module:
```java
opens my.module to dev.kske.eventbus.core;
```
## Polymorphic Event Handlers
On certain occasions it's practical for an event handler to accept both events of the specified type, as well as subclasses of that event.

## Compile-Time Error Checking with Event Bus Proc
To assist you with writing event listeners, the Event Bus Proc (Annotation Processor) module enforces correct usage of the `@Event` annotation during compile time.
