Issues Starting my Simple Spring Boot Application

Question

I am starting to learn Spring Boot following a Pluralsight training.

I am doing a very simple Rest Service using Spring boot and i only have a couple lines of code. So i guess the issue will be in the pom.xml configs.

please see below everything i have:

pom.xml

Answer 1

Based on the information you provided, it seems that you are using an old version of spring (1.3.1.RELEASE) with JDK 10 (as in the first line of the screenshot).

If I were you, I would upgrade spring version to a newer one (such as 2.0.2.RELEASE) or downgrade to JDK 8.
