To use the CommandBridge API in your plugin, add the commandbridge-api dependency to your build and declare CommandBridge as a plugin dependency so it loads first.

Dependency

Add the dependency to your build script.

<dependency>
    <groupId>dev.objz</groupId>
    <artifactId>commandbridge-api</artifactId>
    <version>3.3.4</version>
    <scope>provided</scope>
</dependency>

compileOnly 'dev.objz:commandbridge-api:3.3.4'

compileOnly("dev.objz:commandbridge-api:3.3.4")

Shading the API into your jar is not supported. CommandBridge bundles the API in its own jar and provides it at runtime, so use provided or compileOnly.

Plugin dependency

Declare CommandBridge as a required dependency in your plugin descriptor so it loads before your plugin.

@Plugin(
    id = "myplugin",
    dependencies = { @Dependency(id = "commandbridge") }
)
public class MyPlugin { }

dependencies:
  server:
    CommandBridge:
      load: BEFORE
      required: true
      join-classpath: true

join-classpath: true is required. Paper uses isolated classloaders, so your plugin can't see CommandBridge's API classes without it.

depend:
  - CommandBridge

Getting the instance

Call CommandBridgeProvider.get() to get the API instance. Store it as a field and call it from the right lifecycle method.

import dev.objz.commandbridge.api.CommandBridgeAPI;
import dev.objz.commandbridge.api.CommandBridgeProvider;

private CommandBridgeAPI api;

@Subscribe
public void onProxyInitialize(ProxyInitializeEvent event) {
    api = CommandBridgeProvider.get();
}

import dev.objz.commandbridge.api.CommandBridgeAPI;
import dev.objz.commandbridge.api.CommandBridgeProvider;

private CommandBridgeAPI api;

@Override
public void onEnable() {
    api = CommandBridgeProvider.get();
}

CommandBridgeProvider.get() throws IllegalStateException if CommandBridge is not installed or has not finished enabling.

If you need to cast to a platform-specific subtype, use the typed overload. It throws IllegalStateException if the registered implementation is not an instance of the requested type:

CommandBridgeProvider.get(MyPlatformExtension.class)
