Hello All,

I am creating a ChatBot using NetBeans 11.1. I am getting this error in DMS while loading of Bot.
ERROR [BotsManager] - ChatBotFactory service not found in jar  AmazonLexRestAccess_V1-1-jar-with-dependencies.jar
ERROR [BotsManager] - Failed to load bot plugin from: AmazonLexRestAccess_V1-1-jar-with-dependencies.jar

Below is the code:-

Kubig:
Did you add all your referenced libraries?

Rajnish@49:
Thanks Kubig...

I am very new to netBeans. so apologies...


While i Clean & Build. Only one Jar file is getting generated. And place the same in bots-repo.
Could you please help where  would need to add those libraries?


I have added reference in my code and pom.xml as well.

import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.AWSStaticCredentialsProvider;
import com.amazonaws.auth.BasicAWSCredentials;
import com.amazonaws.regions.Regions;
import com.amazonaws.services.lexruntime.AmazonLexRuntime;
import com.amazonaws.services.lexruntime.AmazonLexRuntimeClientBuilder;

I am using maven-assembly-plugin to generate one jar file with all dependencies. DMS>>BGS throws error
