Gradle plugin cannot be found in a SpringBoot Application - spring-boot

Question

I have a multi-module setup and when I try to refresh the gradle tasks I see the following error:
Plugin [id: 'org.springframework.boot', artifact: 'org.springframework.boot:spring-boot-gradle-plugin:null'] was not found in any of the following sources:
- Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
- Plugin Repositories (could not resolve plugin artifact 'org.springframework.boot:spring-boot-gradle-plugin:null')
Searched in the following repositories:
maven(https://repo.spring.io/snapshot)
maven2(https://repo.spring.io/milestone)
Gradle Central Plugin Repository

I recently added a new module and ever since I added the module I can see this error; though I have deleted that module the error just does not go away. My build.gradle for the main package looks like this :
plugins {
id 'org.springframework.boot' version '2.1.4.RELEASE'
id 'java'
}
apply plugin: 'io.spring.dependency-management'
group = 'com.pro.review'

sourceCompatibility = '1.8'
