getRPCHandler usage in Ignition 8.0

Module Development
1

Since I upgrade some module to Ignition 8.0, I need to suppress @Override annotation for getRPCHandler. Is it normal ???
to avaid the error : Method doesnot override method from its super class

public class GatewayHook extends AbstractGatewayModuleHook {

...

	@Override
	public Object getRPCHandler(ClientReqSession session, Long projectId) {
		return new GatewayRPCHandler(this.context);
	}

Same result with :

ignition-platform-version 8.0.0
ignition-sdk-version ${ignition-platform-version}-SNAPSHOT

or

ignition-platform-version 8.0.1
ignition-sdk-version ${ignition-platform-version}-SNAPSHOT

The way projects are referenced has changed in 8 – there is no longer a project ID.

The signature for that function is now
public Object getRPCHandler(ClientReqSession session, String projectName)

I believe the gateway-network-function-gateway SDK example needs to be updated, it currently doesn't compile with 8.0.2:

[INFO] --- maven-compiler-plugin:3.2:compile (default-compile) @ gateway-network-function-gateway ---
[INFO] Changes detected - recompiling the module!

Thanks, should be fixed shortly.

Thanks Kevin. While you’re in there, the gateway-webpage-gateway project doesn’t build either:
