running app as jar gives fileNotFoundException - spring

Question

Im attempting to run my spring app as a jar, but i get the below error
java.io.FileNotFoundException: class path resource [org/springframework/web/socket/config/annotation/AbstractWebSocketMessageBrokerConfigurer.class] cannot be opened because it does not exist
It runs fine from intelij(as in my main class can runs using the play button). I find the file under project structure --> Libraries and under external libraries (albeit depracted)
Ive tried to look into it, but everywhere (list of examples below) seem to talk about xml files instead of a class
Spring ClassPathResource - cannot be opened because it does not exist
Class path resource cannot be opened because it does not existHow to avoid "class path resource [...] cannot be opened because it does not exist" in a spring boot application?
java.io.FileNotFoundException: class path resource can't be opened
java.io.FileNotFoundException: class path resource cannot be opened because it does not exist

And what Im sure is the class in question:

import org.springframework.messaging.simp.config.MessageBrokerRegistry;
import org.springframework.web.socket.config.annotation.AbstractWebSocketMessageBrokerConfigurer;
import org.springframework.web.socket.config.annotation.WebSocketMessageBrokerConfigurer
import org.springframework.web.socket.config.annotation.EnableWebSocketMessageBroker;
import org.springframework.web.socket.config.annotation.StompEndpointRegistry
import org.springframework.web.socket.server.support.DefaultHandshakeHandler;
#Configuration
#EnableWebSocketMessageBroker
class WebSocketDefaultConfig extends AbstractWebSocketMessageBrokerConfigurer {
#Override
void configureMessageBroker(MessageBrokerRegistry config) {
// config.enableStompBrokerRelay("/topic/", "/queue/");
config.enableSimpleBroker("/topic/", "/queue/");
config.setApplicationDestinationPrefixes("/app");
}
#Override
void registerStompEndpoints(StompEndpointRegistry registry) {
registry.addEndpoint("/tailfilesep")
// .setAllowedOrigins("*")
// .setHandshakeHandler(new DefaultHandshakeHandler())
.withSockJS()
}
}
Kindly assist me, this has passed frustration. Why is that class not in the jar?

Answer 1

The only thing that worked was creating a new project - copy and pasted all the code, build files everything... lol and its fine.
Intelij corruption somewhere along the line
