spring-boot - 找不到Spring Boot插件

Question

我对gradle项目有问题

我的build.gradle

buildscript {
    ext {
        springBootVersion = '2.1.8.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath(
                "org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

plugins {
    id 'org.springframework.boot' version '2.1.8.RELEASE'
}

apply plugin: 'org.springframework.boot'

group = 'com.demo'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'

repositories {
    mavenCentral()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-actuator'
    implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
    implementation 'org.springframework.boot:spring-boot-starter-security'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    runtimeOnly 'mysql:mysql-connector-java'
    providedRuntime 'org.springframework.boot:spring-boot-starter-tomcat'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
    testImplementation 'org.springframework.security:spring-security-test'
}

当我尝试运行build.gralde时，出现错误

Plugin [id: 'org.springframework.boot', version: '2.1.8.RELEASE'] was not found in any of the following sources:

我不明白，这是什么问题，我已经用Spring Initializer生成了项目

我想，我有问题。
您只需要关闭“离线模式”，它将从仓库中下载
