I'm trying to run a basic Spring Boot code but it is throwing some errors - spring-boot

Question

This is the only file that I created to Start learning Spring Boot.
I'm trying to run a basic Spring Boot code but it is throwing a couple of errors that I couldn't figure it out.
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class CourseApiApp {
public static void main(String[] args) {
SpringApplication.run(CourseApiApp.class, args);
}
}
Console output:
***************************
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.springframework.context.annotation.CommonAnnotationBeanPostProcessor.buildResourceMetadata(CommonAnnotationBeanPostProcessor.java:436)
The following method did not exist:
org.springframework.beans.factory.annotation.InjectionMetadata.forElements(Ljava/util/Collection;Ljava/lang/Class;)Lorg/springframework/beans/factory/annotation/InjectionMetadata;
The method's class, org.springframework.beans.factory.annotation.InjectionMetadata, is available from the following locations:
jar:file:/Users/kranthitalloju/.m2/repository/org/springframework/spring-beans/5.0.3.RELEASE/spring-beans-5.0.3.RELEASE.jar!/org/springframework/beans/factory/annotation/InjectionMetadata.class
The class hierarchy was loaded from the following locations:
org.springframework.beans.factory.annotation.InjectionMetadata: file:/Users/kranthitalloju/.m2/repository/org/springframework/spring-beans/5.0.3.RELEASE/spring-beans-5.0.3.RELEASE.jar
Action:
Correct the classpath of your application so that it contains a single, compatible version of org.springframework.beans.factory.annotation.InjectionMetadata
Here is the pom.xml file I'm using to deploy the basic Spring Boot app.

Since you're using the spring-boot-starter-parent, many versions are managed for you out of the box. Also, the spring-boot-starter-web already includes your other dependencies.
You can simplify your pom.xml like so:
<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">
<modelVersion>4.0.0</modelVersion>
<name>Java SprinBoot Course API</name>
<groupId>org.codeapi.springboot</groupId>
<artifactId>APIDemo</artifactId>
<version>0.0.1-SNAPSHOT</version>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.3.4.RELEASE</version>
</parent>
