I am not be able to import correctly ResponseEntityExceptionHandler
class ControllerAdvice #Autowired()() extends ResponseEntityExceptionHandler{
What I am missing in my pom xml file?
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.6.RELEASE</version>
<relativePath/>
</parent>
try Add it inside dependency instead of the parent. parent is a base pom of your project.
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.6.RELEASE</version>
</dependency>
</dependencies>
Hi try to add this dependency
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
You have added the dependency of spring-boot-starter-parent which does not contain spring-web dependency. ResponseEntityExceptionHandler class comes from spring-web. So, you can add below dependency to the pom:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
</dependency>
or you can use spring-boot-starter-web artifact which includes spring-web by default.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<version>2.1.9.RELEASE</version>
</dependency>
For more info you can look at pom of spring-boot-starter-web and spring-boot-starter-parent you see the dependencies that those artifact includes.

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.
I'm building a multi modules maven project with 4 modules. For two of them (the one with the rest controller and the one with the core business logic) I need the power of the dependency injection. But is not working at all. Here my parent pom:

The package inside the two project (service and core) are the same: com.example.application (where is the main class with #SpringBootApplication in the service project), com.example.application.restcontroller (where is the controller in the service project), com.example.application.core (where is the #component that I can't inject in the core project).
Inside the core project I have, under the com.example.application.core a #Component that I would inject inside the class into the service project under the com.example.application.restcontroller package.
Within the same project and under the package of the main class, the dependency injection works absolutely fine. Between two different modules I can't achieve that (nullPointerException).
Any advice will be appreciated
Your description about the packages is hard to understand. But, it most likely is a Component scanning issue. Make sure that you are scanning all the packages. For instance, In the taskexecutor-service, you can do:
#ComponentScan(basePackages = {"com.example.taskexecutor", "com.example.application"})

Could anyone please help how to achieve it in spring boot
You can get benefit of spring-boot dependency management by adding the spring-boot-dependencies artifact with scope=import.
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-dependencies</artifactId>
<version>2.1.9.RELEASE</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
Without the parent POM, you no longer will benefit from plugin management. You need to add the spring-boot-maven-plugin explicitly.
To use a different version for a certain dependency than the one managed by Boot, you need to declare it in the dependencyManagement section, before spring-boot-dependencies is declared.
In my spring starter project, I am trying to do API calls using the JPA. My pom.xml look like this:

<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
When I try to run it is getting error as
java.lang.NoClassDefFoundError: com/fasterxml/jackson/databind/Module
spring-boot-starter-web already includes Jackson. You should not override the managed version, otherwise the versions can be different between different Jackson libraries, causing ClassNotFoundException.
Remove this from the pom:
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.8.5</version>
</dependency>
and let the transitive dependency with the correct version be used.
Or when you add Jackson to your pom, just don't use any version number, since parent project dependency management already includes all jackson libraries with a consistent version.
Try 2 options :
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.8.8</version>
or
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.7.3</version>
If you are using SpringBoot you should know that Jackson is added by default. so remove to avoid conflicting versions and it should work.
I have a maven project with jdk: 1.8, spring-boot: 1.5.4.RELEASE, spring: 4.3.9.RELEASE, and some vendor dependencies. The project builds and runs but when I access resources used by vendor packages, I get following exception:

I have the same issue today. It cost me several hours to find the reason.
You just have a conflict with your log4j jar.
The quick fix for this is :
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>log4j-over-slf4j</artifactId>
</exclusion>
</exclusions>
</dependency>
If you really need log4j, then add the dependency:
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
</dependency>
You can check log4j-over-slf4j to know the detail.
I have encountered similar issues and all of mine were solved by making sure the version I was using was the most updated and that is is compatible with the rest of the code. With your problem, it looks as if the .jar is specifically built to be compatible so I doubt that's the issue. Only things I can think of given the information at hand is:
1.) Try making sure all .jar's being used are newest version. (Sometimes if your other .jar's are not completely updated, they can throw errors/exceptions when trying to access a method from a .jar that is a version ahead.)
2.) If "1" doesn't do it, try using a dependency import function in an IDE. I have had many occurrences where Maven was just causing odd errors from IDE compatibility. Importing all .jar's from a "Dependency" menu could also help.
