I resolve it by

repositories {
    mavenCentral()
    maven {
        url 'https://maven.springframework.org/milestone/'
    }
}

But what I don’t understand is the reposoitory has been sepcify in the POM of https://repo.maven.apache.org/maven2/com/microsoft/azure/spring-cloud-azure-dependencies/1.1.0.M4/spring-cloud-azure-dependencies-1.1.0.M4.pom

Do I need to sepcify in build.gradle?
