Json webtoken dependency will not resolve in pom.xml

I am currently working on a Spring Project, which I am new to, and have no idea why this dependency I got from the maven repository will now resolve itself. I have tried to use both the separated dependency (jjwt-api, etc..) and the one pasted in my pom.xml below but it will not resolve. If anyone can help me figure this out that would great appreciated.

The MvnRepository page says, it's in the central repo, and the central repo link to the pom.xml of the dependency also works: https://repo1.maven.org/maven2/com/auth0/java-jwt/3.18.3/java-jwt-3.18.3.pom
So did you maybe try to resolve it once when you were offline? Failed resolving also is cached in your local maven repo, so you might have to clean that up. You can try to use
mvn dependency:get -Dartifact=com.auth0:java-jwt:3.18.3
or you clean the cached "missing" dependency manually: go to your local maven repo (usually in ~/.m2/repository), descend to com/auth0/java-jwt and remove the folder 3.18.3 inside, then run your maven build again.

I just reloaded the pom.xml file and it the works.

Spring Maven: Correct the classpath of you application

I am getting the following error when trying to run my spring project:
Description:
An attempt was made to call a method that does not exist. The attempt was made from the following location:
org.hibernate.cfg.annotations.EntityBinder.processComplementaryTableDefinitions(EntityBinder.java:1236)
The following method did not exist:
'javax.persistence.Index[] javax.persistence.Table.indexes()'
The calling method's class, org.hibernate.cfg.annotations.EntityBinder, was loaded from the following location:
jar:file:/C:/Users/bobal/.m2/repository/org/hibernate/hibernate-core/5.4.14.Final/hibernate-core-5.4.14.Final.jar!/org/hibernate/cfg/annotations/EntityBinder.class
The called method's class, javax.persistence.Table, is available from the following locations:

The called method's class hierarchy was loaded from the following locations:

Action:
Correct the classpath of your application so that it contains compatible versions of the classes org.hibernate.cfg.annotations.EntityBinder and javax.persistence.Table
Process finished with exit code 1
I think that this error may be due to having conflicting versions of some dependencies, but I'm not very sure. This is my first ever Spring project.

If you find anything wrong please feel free to point it out and explain why. Trying to learn as much as I can.

You have multiple version of JPA libraries, that's why you are getting this error.
jakarta.persistence-api-2.2.3.jar and
hibernate-jpa-2.1-api-1.0.0.Final.jar
You can remove hibernate-jpa-2.1-api-1.0.0.Final.jar dependency because it is also present in jakarta.persistence-api-2.2.3.jar.

How to build a multi-module Maven project without a main class in one of the modules

I've been trying to find an answer to this issue in similar questions but I still don't know what is causing it.
I have a multi-module maven project and I'm trying to run mvn install or mvn package and I get the following error

I have something very similar to the structure of this project (sfg-pet-clinic), however, after downloading and running mvn package, it works fine. I don't see much difference between the pom files of my project and this one so what could I be missing?

Configuration is for older versions of spring.
Remove:
<configuration>
<skip>true</skip>
</configuration>
Instead, add this flag below pom artifactId
<properties>
<spring-boot.repackage.skip>true</spring-boot.repackage.skip>
</properties>
Like so:
<parent>
<artifactId>mc-pet-clinic</artifactId>
<groupId>guru.springframework</groupId>
<version>0.0.1-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<artifactId>pet-clinic-data</artifactId>
<properties>
<spring-boot.repackage.skip>true</spring-boot.repackage.skip>
</properties>
...

I would move the entire
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
section from the parent to the module-app module, because that one is the single module which uses the repackage functionality.
Moreower I would delete the plugin section from the module-data too, because there is no need to repackage that module.

Thanks to #wemu on the comments section.
Adding this:
<configuration>
<mainClass> ${your.start.Class}</mainClass>
</configuration>
to the plugin section is required on version 2.1.1.RELEASE of the spring-boot-starter-parent dependency, as long as your class is in another module.
The project sfg-pet-clinic I referred to in my question uses an older version which does not need the <mainClass> configuration

Okay here is how I fixed that.
My Steps were:
Change the packaging of pom.xml file for project-data to pom from
jar (I used overview of Eclipse)
add <type>pom</type> in pom.xml file for project-app for dependency of module-data
<dependency>
<groupId>samee.springframework</groupId>
<artifactId>project-data</artifactId>
<version>0.0.1-SNAPSHOT</version>
<type>pom</type>
</dependency>
Then you can run your clean and package/install

I just changed the Spring Boot version in the parent pom.xml from 2.1.1 to 2.0.3 and it works.
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.3.RELEASE</version>
<relativePath /> <!-- lookup parent from repository -->
</parent>
Would be better to make it work in 2.1.1 though, but that's a quick and simple solution.

java.lang.NoClassDefFoundError: org/springframework/core/env/ConfigurableEnvironment

I am trying to write a simple RESTful service using Spring Boot. However, there is an error message I am not able to solve. I have been researching and it looks like it is a conflict between SpringBoot versions, however I am not sure about how can I get rid of it.
I have this SpringBootApp:
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* REST Service application
*/
#SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}

Recommended Approach
Go to Spring boot Initialzr site and select web stack as a dependency as shown in below .
As Spring Boot uses the concept of Opinionated dependencies and Bill of Materials, It will automatically pull the other dependencies and resolve your classNotFoundException issue. And in your case it misses out the Spring-core-4.2.4.RELEASE.jar dependency.
Execute the Maven Goal as clean install spring-boot:run -e and you can find your maven dependencies in your IDE and below given is a sample POM file.

Spring boot is running -
<spring.version>4.3.2.RELEASE</spring.version>
For -
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<version>1.4.0.RELEASE</version>
</dependency>
While you are importing -
<springframework.version>4.3.0.RELEASE</springframework.version>
You can confirm on the master pom -
https://github.com/spring-projects/spring-boot/blob/v1.4.0.RELEASE/spring-boot-dependencies/pom.xml
Can you update the spring version in your pom? Or deal with managing maven dependencies

Delete the springframework folder in repository, then press Alt + F5 and update the project (force update snapshot).
C:\Users\xxxx\.m2\repository\org\springframework

changed the boot-starter-parent version from 1.5.1.RELEASE to 1.4.0.RELEASE.

<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.4.2.RELEASE</version>

Please Try this one for your parent

I had same problem with Spring boot 2.1.9.RELEASE
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.9.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
Added pom dependency eliminated this exception:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>5.2.0.RELEASE</version>
</dependency>
EDIT - better approach.
Also clean up of maven repository with spring dependencies resolved problem for me, there were not need to add spring-core 5.2.0.RELEASE in pom. Seems that when I had many versions of spring in repo some problem occurs. Also before again resolve dependencies dont forget clean project.
rm -rf ~/.m2/repository/org/springframework/

For me changing all
<version>2.4.10</version>
to
<version>2.4.3</version>
in pom.xml file worked.

I changed the boot-starter-parent configuration which was runnig version 2.0.0 to 1.4.0 and I was able to run the java application and got rid of this error
<parent>
<groupId>org.springframework.boot</groupId>

<version>1.4.0.RELEASE</version> <!-- changed it to version 1.4.0 from 2.0.0-->
