I've spent the past two days attempted to get Spring Boot to work. However, I have been unable to get a brand new, clean project to run inside of IntelliJ Idea.
Here's what I'm doing:
Open IntelliJ Idea
Create a new project with Spring Initializr with the dependencies Security, Web, Rest Repositories, JPA, H2, and Actuator.
Run the Java file called Application.java
Get this output.

Note: I have a section in the dependencies where I label the things I added by hand. These are things that Spring Initializr did not automatically add (and should have), so I needed to add them manually to get the project to run.
I believe the issue has to do with my IntelliJ Idea setup, since running a new project in STS (Spring Tool Suite) runs fine.
Some other things I've tried and still getting the same result:
Using the web version of Spring Initializr.
Creating a new Spring Boot project without any libraries
Downloading sample projects and running them.
Adding dependencies that have this library manually via Maven.
Creating then project in STS and importing it into IntelliJ Idea.
Basically anything within the first ten pages of Google Search results for the issue.
Any help would be quite helpful.
Thanks,
Nathan

Problem Statement
I am receiving the following exception when I run my Spring Boot application.
***************************
APPLICATION FAILED TO START
***************************
Description:
An attempt was made to call a method that does not exist. The attempt was made from the following location:
org.hibernate.cfg.AnnotationBinder.bindJoinedTableAssociation(AnnotationBinder.java:2548)

How to I remove one of the versions of javax.persistence.JoinTable?
Multiple javax.persistence.JoinTable
The issue is most likely related to the duplicate javax.persistence.* libraries. I see you have the following two dependencies
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
Remove the org.springframework.data.spring-data-jpa dependency.
The org.springframework.boot.spring-boot-starter-data-jpa dependency already includes org.springframework.data.spring-data-jpa which is being added transitively.
Make sure to run a mvn clean before packaging and testing the new jar file
Non Maven lib directory
It also looks like there is a lib directory in your project that may have dependencies that are not managed by Maven. Please delete at least the javax.persistence library from that location
Ok...for the first time in my life as a Developer I have no Idea how to fix this error.
I'm having issues with Maven commands and Intellij.
(IMPORTANT)
All maven commands on local project isn't working and returns the error:
cannot find or load main class #, java.lang.ClassNotFoundException: #
Detail for the "#" on the error message.

I tried to delete .m2/repository folder but it didn't work.
I tried to 'Settings > Build, execution, deployment > Build Tools > maven > Importing' and set the import as 'project JDK' but it didnt work. (I'm using JDK 11, and it was working before)
I tried to update the maven repositories by Intellij (remote and local) and now I have a error from remote repository (can't find any imported package classes)
The only thing I did that solve it once, was recreate the project as a new one and add all the classes and pom.xml, but when I added my configuration files it broke again.
I'm using a proxy from production (.maven/jvm.config)
# -Dhttp.proxyHost=<proxy_host>
# -Dhttp.proxyPort=<proxy_port>
# -Dhttps.proxyHost=<proxy_host>
# -Dhttps.proxyPort=<proxy_port>
But the lines are all commented right?
And application.properties:
server.address=0.0.0.0
So...This is being a very anoying problem, and I'm lack of ideas. Maybe I'm gonna try to recreate the project AGAIN and reimport each file to see which is the broken one, but if someone had this issue before and fixed it...how?
Empty or delete .maven/jvm.config file, it's loaded directly and added to the command line, the comments syntax is not supported.
I'm having trouble deploying my WAR file to elastic beanstalk (Tomcat). I've downloaded the logs and I'm getting a bunch of errors https://pastebin.com/bVTjLJDD
I tested this WAR file successfully with Apache Tomcat deployed locally on my PC, so I don't know what is causing these errors.

I've extended SpringBootServletInitializer in the main class. As seen in pom.xml I also set the tag for the tomcat dependency. Everything works fine when tested on the local Apache Tomcat server. What could be the issue here?
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'defaultValidator' defined in class path resource [org/springframework/boot/autoconfigure/validation/ValidationAutoConfiguration.class]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: Could not initialize class org.hibernate.validator.internal.engine.valueextraction.ValueExtractorManager
Might be because of this, the war is not deployed.
Make sure you have all the libraries in place while making the WAR.
Please check the library is used only for compile or something.
I have a spring boot application having starter-data-jpa dependency added to pom.xml. I can clearly find the javax.persistence package present in maven dependency section. But I am unable to use #Entity annotation. Upon manually entering import javax.persistence.Entity eclipse shows unresolved dependency.
Thanks in advance.
here is my pom.xml file.

You're specifying <scope>test</scope> for the JPA starter, which specifically tells Maven that you only want that dependency available for test classes. Remove the scope and it should work.
Try removing <scope> for dependency JPA starter from pom.xml, do mvn clean install -U. this should solve your issue.
You should remove <scope>test</scope> from the spring-boot-starter-data-jpa dependency first.
If it still doesn't work, verify that your project runs when using Maven directly, by using the following command within a terminal:
mvn spring-boot:run
If this command works, reimport your project within your IDE, and test again. Often, the IDE doesn't immediately update the classpath, and is at fault.
Hi. I'm studying Java Web and created an application using Spring Boot and Maven.
The application is working fine using mvn spring-boot:run.
How do I compile or build it to send it to someone?

In your pom.xml if spring-boot-maven-plugin is not available then first make sure that, it is available in your pom.xml(you already do that).
Spring-boot project outcome is a simple jar file. This jar file include all the file it needed, embedded tomcat etc.
Go to your project directory from command line. Say for example your project root folder name is ABC, then go to /ABC folder and run the command.
mvn package
After running this command successfully, you find a folder named /target. Inside the /target folder your find your jar file. Run the jar using java -jar ABC.jar command or share your jar with others.
If you want to create an installer for your application you can use
