How to troubleshoot SpringBoot POM issues - spring-boot

As the question says, I have the below POM for instance:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</project>
This POM is letting me compile the Microservice without any problem on machine 1. But on machine 2, I am getting error during build stating that
Dependency org.springframework.cloud:spring-cloud-config-server:${project.version} not found
I tried few changes and changing the Hoxton version from SR3 to SR8 is letting the project build.
What kind of discrepancies cause these builds to fail on one and pass on the other. How does on troubleshoot these issues.
Any pointers will help as I am running into the trivial problems lately.
Thanks a lot.

Intellij / Spring Security - unable to expand - spring-security-oauth2-core dependency?

When I am analyzing dependencies in intelij using Analyze Dependencies.. feature, i am seeing that at one hierarchy i am able to expand spring-security-oauth2-core and I am not able to expand the same at different hierarchy. Why is this so.
Able to expand below -
Unable to expand below -
Seems quite trivial, but if I am looking at a new dependency I would not be able to determine for sure if it's an end-node (i.e has no further deps) until I can find an answer for this Q.
Edit - Below is the pom.xml if some one want to try at there end.

Unable to create a simple spring Boot Gateway api

I am trying to create a simple spring boot Gateway project. Below is the POM.xml for the same. When the dependencies are loaded it shows it has an error. On verification, I found the gateway jar is not getting loaded. I tried to update the maven project and even refresh but nothing is working.
Error: Could not find or load main class photoappGateway.GatewayApplication Caused by: java.lang.ClassNotFoundException: photoappGateway.GatewayApplication
Can you help me to understand what I am doing wrong or where I am making mistake?
Also I am able to create a simple app with web,eureka client dependency. That one works fine.

Can't enable actuator into spring cloud gateway Greenwich

I just installed a Spring Cloud Gateway server (Greenwich.SR2) with Boot Actuator starter dependency, but can't reach any /actuator/gateway or /gateway API
I tried to activate and publish the endpoint, without success :
management.endpoint.gateway.enabled=true
management.endpoints.web.exposure.include=health,gateway

I acknowledge that this is a WebFlux+Netty server, but this is not supposed to make any difference from what I read. I must have missed something, though.
Any experience to share, someone?
Ok, here goes the shame moment...
There is no API at /actuator/gateway; the API is at /actuator/gateway/routes and so on!

why #HystrixCommand which is the annotation of spring injected is failed?

The pom file of my service which is maven project as follow:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

And the part source code of my service as follows:
#HystrixCommand(fallbackMethod = "reliable")
public String readingList(){
URI uri = URI.create("http://localhost:8090/recommended");
return this.restTemplate.getForObject(uri, String.class);
}
My question is, when I import com.netflix.hystrix.contrib.javanica.annotation.HystrixCommand, it is not recognized. Anyone encountered this same problem?
Please tell me about how did you resolved it.
Thanks.
According to the latest POM file, it has been deprecated in favour of spring-cloud-starter-netflix-hystrix. STS didn't help me to add the import either, so you might need to add it manually:
import com.netflix.hystrix.contrib.javanica.annotation.HystrixCommand;
