intellij Gradle Sync Error : "Could not resolve all artifacts for configuration ':classpath'." - spring-boot

Question

This is my build.gradle
buildscript {
ext {
springBootVersion = '2.1.7.REALEASE'
}
repositories {
mavenCentral()
jcenter()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
}
}
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'
group 'org.example'
version '1.0-SNAPSHOT'
repositories {
mavenCentral()
}
dependencies {
compile('org.springframework.boot:spring-boot-starter-web:')
testCompile('org.springframework.boot:spring-boot-starter-test:')
}
and this is the Sync ErrorMessage
Could not resolve all artifacts for configuration ':classpath'.
Could not find org.springframework.boot:spring-boot-gradle-plugin:2.1.7.REALEASE.
Searched in the following locations:
- https://repo.maven.apache.org/maven2/org/springframework/boot/spring-boot-gradle-plugin/2.1.7.REALEASE/spring-boot-gradle-plugin-2.1.7.REALEASE.pom
- https://jcenter.bintray.com/org/springframework/boot/spring-boot-gradle-plugin/2.1.7.REALEASE/spring-boot-gradle-plugin-2.1.7.REALEASE.pom

Possible solution:
Declare repository providing the artifact, see the documentation at https://docs.gradle.org/current/userguide/declaring_repositories.html
There are clearly declared repositories like mavenCentral() and jcnenter(), but can't build it.

Answer 1

I was told jcenter no longer be serviced, so I changed dependencies and deleted jcenter().
This build is successfully worked.
buildscript {
ext{
springBootVersion = '2.1.7.RELEASE'
}
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
}
}
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'
group 'org.example'
version '1.0-SNAPSHOT'
repositories {
mavenCentral()
}
dependencies {
testImplementation 'org.junit.jupiter:junit-jupiter-api'
testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine'
}
test {
useJUnitPlatform()
}
