Could not find artifact org.springframework:springloaded:jar:2.1.3.RELEASE in spring-releases (http://repo.spring.io/libs-release)

Question

I'm brand new to Java. I'm following https://spring.io/guides/gs/rest-service/#scratch (mostly). I'm at the point of standing up the web service, but I'm getting the error in the title.

I'm running

./mvnw clean package

My pom.xml is

Questions that have not helped:

Missing artifact org.springframework.boot:spring-boot-starter-parent:jar:1.3.2.RELEASE

The recommendation is to use a parent tag, but I have

<parent>
   <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.3.RELEASE</version>
</parent>

In my pom.xml and that doesn't solve the issue. I tried adding the dependecyManagement tag, but got the error

package org.springframework.boot does not exist

Maven and Spring Boot - non resolvable parent pom - repo.spring.io (Unknown host)

This is different from my error message. Also, the recommended solution is to check if you can access http://repo.spring.io/, which I can.

Spring boot , pom.xml

This is another network issue. I should have a direct network connection.

(Basically all the quetions I found the answer is parent, dependencies, or network issues, all of which I can rule out.)
