Empty WEB-INF/classes in the generated war file (Spring boot maven project)

I'm trying to run my spring boot application with maven from my virtual machine with CLI, but I have got this error :
Could not find or load main class start.Application
Caused by: java.lang.ClassNotFoundException: start.Application
I figured out that in war file, WEB-INF/classes is empty:

In case, someone is facing issue with wro4j for PetClinic application.
Change wro4j version to 1.9.0, it works for openjdk version "11.0.3" 2019-04-16
<wro4j.version>1.9.0</wro4j.version>

You are using a wrong version in you Spring-boot parent dependency. You should use 2.0.6-RELEASE, or any other RELEASE version.
<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-parent -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.6.RELEASE</version>
<type>pom</type>
</dependency>
Hope it helps!

Which Java-Version do you use?
When building Spring petclinic on Java 9 or higher, problems with wroj have been reported https://github.com/wro4j/wro4j/pull/1041 .
These problems are solved in the code of wroj after version 1.8.0 https://github.com/wro4j/wro4j , but no version with this solution has been released https://github.com/wro4j/wro4j/branches .
So you have to build wroj version 1.8.1-SNAPSHOT yourself and use this version to build petclinic framework-version on Java 9 or higher.

We can fix this issue by simply run the below command from terminal/command prompt:
mvn spring-javaformat:apply

Code run in STS has no issues, crashes when run from command line

I am sure this is an easy configuration issue of some kind but I can not find it. When I run my java code in STS
Spring Tool Suite
Version: 3.8.3.RELEASE
Build Id: 201612191457
Platform: Eclipse Mars.2 (4.5.2)
All runs well. No errors, no issues. The code does everything it should.
When I build the jar with mvn package from the command line and then try to run it I get:

I have checked everything I know to check and am at a loss. I feel like this must be a build setting someplace I have missed but I can not find anything.
