Could not find method pluginManagement() for arguments

I am facing following issue while building spring boot project with gradle

What went wrong: A problem occurred evaluating settings 'ConfigurationManager'.

Could not find method pluginManagement() for arguments [settings_4czoxeapfgxghi54ogzhrlgs9$_run_closure1@6e5e4ee] on settings 'ConfigurationManager' of type org.gradle.initialization.DefaultSettings.

Content of settings.gradle is as follows

pluginManagement {
    repositories {
        gradlePluginPortal()
    }
}
rootProject.name = 'ConfigurationManager'

Content of gradle-wrapper.properties is as follows

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-5.4.1-bin.zip
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists

Content of build.gradle is as follows

plugins {
    id 'org.springframework.boot' version '2.1.6.RELEASE'
    id 'java'
    id 'war'
}

apply plugin: 'io.spring.dependency-management'
