How to fix "plugin was not found in any of the following sources"

Question

I created a Spring MVC project ion Intellij IDEA. When I build my project, following message is displayed, how can I resolve it?

Plugin [id: 'org.springframework.boot', version: '2.1.7.RELEASE'] 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:org.springframework.boot.gradle.plugin:2.1.7.RELEASE')
  Searched in the following repositories:
    Gradle Central Plugin Repository

Answer 1

I saw the problem even on command line and it helped when I added plugin management to the start of setting.gradle file:

pluginManagement {
    repositories {
        maven { url "https://plugins.gradle.org/m2/" }
        gradlePluginPortal()
    }
}
