java.lang.NoClassDefFoundError:org/springframework/web/util/UriTemplateHandler

I have a basic SpringBoot application that I created using Spring Initializer. When I try to start the SpringBoot server( using the maven plugin (spring-boot:start) it gives the below error.

java.lang.NoClassDefFoundError: org/springframework/web/util/UriTemplateHandler at java.lang.Class.getDeclaredConstructors0(Native Method) ~[na:1.8.0_60] at java.lang.Class.privateGetDeclaredConstructors(Class.java:2671) ~[na:1.8.0_60] at java.lang.Class.getDeclaredConstructors(Class.java:2020) ~[na:1.8.0_60] at org.springframework.boot.context.properties.ConfigurationPropertiesBindConstructorProvider.findConstructorBindingAnnotatedConstructor(ConfigurationPropertiesBindConstructorProvider.java:62) ~[spring-boot-2.2.4.RELEASE.jar:2.2.4.RELEASE] at org.springframework.boot.context.properties.ConfigurationPropertiesBindConstructorProvider.getBindConstructor(ConfigurationPropertiesBindConstructorProvider.java:48) ~[spring-boot-2.2.4.RELEASE.jar:2.2.4.RELEASE] at org.springframework.boot.context.properties.ConfigurationPropertiesBean$BindMethod.forType(ConfigurationPropertiesBean.java:311) ~[spring-boot-2.2.4.RELEASE.jar:2.2.4.RELEASE] at org.springframework.boot.context.properties.ConfigurationPropertiesBeanDefinitionValidator.validate(ConfigurationPropertiesBeanDefinitionValidator.java:63) ~[spring-boot-2.2.4.RELEASE.jar:2.2.4.RELEASE] at org.springframework.boot.context.properties.ConfigurationPropertiesBeanDefinitionValidator.postProcessBeanFactory(ConfigurationPropertiesBeanDefinitionValidator.java:45) ~[spring-boot-2.2.4.RELEASE.jar:2.2.4.RELEASE] at org.springframework.context.support.PostProcessorRegistrationDelegate.invokeBeanFactoryPostProcessors(PostProcessorRegistrationDelegate.java:286) ~[spring-context-5.2.3.RELEASE.jar:5.2.3.RELEASE] at org.springframework.context.support.PostProcessorRegistrationDelegate.invokeBeanFactoryPostProcessors(PostProcessorRegistrationDelegate.java:174) ~[spring-context-5.2.3.RELEASE.jar:5.2.3.RELEASE]

Spring boot is of version 2.2.4 it requires Spring 5 (basically it comes with a predefined version of spring

On the other hand you're using "hardcoded" spring web 4.1.4 which is wrong:

 <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
    <version>4.1.6.RELEASE</version>
 </dependency>

You should be using instead of that:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

Make sure you don't have any of spring 4.x dependencies on your path (by running mvn dependency:tree)

In addition, you don't need to place:

  <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter</artifactId>
  </dependency>

And one last thing, you're using lombok which is fine of course (I mean spring can play nicely with lombok), but spring boot maven plugin will still package it into the artifact despite the provided scope. If you wish to exclude it from the final artifact, you'll have to configure the spring boot maven plugin itself to do so.
