I am trying to run a Small basic Spring boot program on my machine and I when I run clean compile
(even before trying spring-boot:run) on maven I get the following Error :

Here is my Pom.xml :

And here is my java Class :
package com.benayed.spboot.poc.SpringBootPoc; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class SpringBootPocApplication { public static void main(String[] args) { SpringApplication.run(SpringBootPocApplication.class, args); } }
I tried many solutions I could find on internet, such as deleting the .m2 repository, adding different tags (version, fork,…) to the spring-boot-maven-plugin
plugin which, I’m pretty sure, is the part causing the problem
Any suggestions ?

Answer
You have 0 compile dependencies, only test-compile dependencies defined, because you’ve commented out spring-boot-starter-data-jpa
. Spring starter’s pull other dependencies in (including other starters) to create everything needed at compile time. Un-comment the spring-boot-starter-data-jpa
dependency, and/or re-evaulate what dependencies you actually want.
