I have a server side project written in java including mavenand spring-boot
And I’m trying to run it in Docker.
I write the whole program in VSCODE and create a special Dockerfile for it.
Then I want to be able to create a jar from my project and when I build an image and run it in the container I can see server side.

this is my Dockerfile:

FROM maven:3.8.1-openjdk-11 AS build
WORKDIR /usr/src/app
COPY pom.xml .
COPY src ./src
RUN mvn package
ENTRYPOINT ["java","-jar","target/my-app-1.0.0.jar"]

this is my pom.xml:

MyApplication.java:

package src;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class MyApplication {
    public static void main(String[] args) {
        SpringApplication.run(MyApplication.class, args);
    }
}

And my folder structure is like this:

 .
 ├── src
 |   └──controllers
 |   │  └──controller.java
 |   └──models
 |   │  └──classA.java
 |   |  └──classB.java 
 |   └──services
 |   |  └──service.java
 |   └──MyApplication.java
 ├── Dockerfile
 ├── pom.xml

When I run the docker build -t app command. There seems to be no problem and the build is successful, but when I later run the command docker run -p 8080:8080 app I get this error
Error: Could not find or load main class src.MyApplication Caused by: java.lang.ClassNotFoundException: src.MyApplication

Does anyone have an idea for a solution for me?
