Can't find RemoteSpringApplication on Intellij for live reload on Docker - spring

I'm currently trying to run a Docker SpringBoot Project with live reload using SpringBoot Devtools and following this documentation
I made the changes in my POM.xml
<?xml version="1.0" encoding="UTF-8"?>

</project>
And added the secret configuration on my application.properties
spring.devtools.remote.secret=${SPRING_REMOTE_SECRET:secret}
When I try to create de Intellij configurarion to use the RemoteSpringApplication as main class
it cannot find the class, in fact it does not find the org.springframework.boot.devtools whole package.
The application is running in Docker container created from this Dockerfile
FROM openjdk:11
WORKDIR /app
COPY target/hello-0.0.1-SNAPSHOT.jar /app/hello-ms-0.0.1-SNAPSHOT.jar
ENTRYPOINT ["java","-jar", "/app/hello-0.0.1-SNAPSHOT.jar"]
And except for the live reload functionality, it is working. Am I missing something?
Edit 1: There was a problem with the scope of the devtools plugin. (thanks #xerx593)
Edit 2: THe live reload and devtools seems to be working fine and if I run the application locally with mvn spring-boot:run, it reloads when changes are made in the project. The problem is running the project via SpringRemoteApplication that IntelliJ can't find so I can configure it as main class

I was finally able to resolve it . The problem was that the spring boot 2.5.0 was using tomcat 9.0.46 by default while my system had tomcat 9.0.0.M15 . So when I ran the application as "run on server" the tomcat 9.0.0.m15 added to my class path and then when ever I was doing run as java applicationit was throwing the error. Clearing the tomcat embedded repo from .M2 path and updating the local system with tomcat 9.0.46 fixed the problem

Spring-boot(maven) actuator,devtools not working

I'm a newbie to spring-boot. Trying to create a simple web application using spring-boot maven. Basic static page display using dependency spring-boot-starter-web worked fine. When I included spring-boot-devtools and spring-boot-starter-actuator in pom.xml it is giving build error Re-run Maven using the -X switch to enable full debug logging.
I tried including spring-webmvc dependency in pom file, still the result is same.

I downloaded this project from spring.io (SPRING INITIALIZR website). Build project is getting failed.
<scope>runtime</scope> of spring-boot-devtools suppose not to be runtime. In fact according to the doc -
Developer tools are automatically disabled when running a fully
packaged application. If your application is launched from java -jar
or if it is started from a special classloader, then it is considered
a “production application”. Flagging the dependency as optional in
Maven or using a customdevelopmentOnly configuration in Gradle (as
shown above) is a best practice that prevents devtools from being
transitively applied to other modules that use your project.
So, change the dependency as below -
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<optional>true</optional>
</dependency>
you can update your pom.xml and change the version number to any previous stable version.It worked for me.

<artifactId>spring-boot-starter-parent</artifactId>

What dependency is missing from this Spring Boot Application?

I would like to create a Spring boot Web application with H2 database and JPA support. But STS throws an error at pom.xml overview :
Missing artifact org.springrfamework.boot:spring-boot-test.jar:1.5.6.RELASE (Click for 49 more)
Here is my pom.xml , I have no idea what's the problem.

Actually your ide not getting the dependency, you should clean build again and if still showing error then simply remove that dependencies from your local repository (I. e. ./.m2 if using maven) and clean build your project again then all required dependencies will be downloaded I your local.
Command mvn clean compile package install

In Eclipse STS the project structure looks like following:-
Now if I run my application using IDE then everything works fine. Or if I build using apache-maven (mvn clean package) and run through cmd (java -jer target/spring-boot-web-jsp-0.0.1-SNAPSHOT.jar) also works fine. It ended with opening the following web page:-
But my understanding from here also says if I double click on the executable spring-boot-web-jsp-0.0.1-SNAPSHOT.jar should also open above web page.
Is my understanding wrong or I am doning something wrong?
As M.Deinum pointed out in comments, it's not possible to develop a web application whose view technology is JSP and build as an executable jar. In order to do so either, you have to change the view technology or change build type to war.

Spring Boot multi module Maven project deployment

We have multi module Maven project with following modules:
Commons
Model
Repository
Service
Web
We've googled around and we didn't found a solution how to make one executable jar when project has this kind of structure.
Here is the parent pom.xml:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<groupId>...</groupId>

</dependency>
</dependencies>
</project>
So, very basic parent pom.xml. We know that we can't use Spring Boot Maven plugin when packaging is pom, so we've defined it in pom.xml from Web module:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</project>
The rest of pom.xmls from other modules are pretty much the same: Service's pom.xml includes Repository.jar, Repository includes Model and Common.
Problem 1: when we run mvn install, plugin creates fat jar in target folder of web module. But when we try to run it with java -jar name-of-jar it gives java.lang.NoClassDefFoundError about some class from Service module - and you can see from Web's pom.xml that Service module is included (there is also a Service.jar packed as library in Web.jar)
Problem 2: what's interesting is that Service.jar inside of Web.jar also contains pretty much all the dependencies that are already present in Web.jar - basically they are duplicated.
Did anyone managed to create executable fat jar using Spring Boot Maven plugin and Maven Module project structure?
Problem 1 & 2
You should not have devtools as dependency in your parent pom.
Move the following to the web/spring-boot module:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
</dependency>
If you look at devtools's pom, it includes the following:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-autoconfigure</artifactId>
</dependency>
So your service jar ends up with some spring boot dependencies.
