外掛查庫：

settings.gradle中的程式碼：

pluginManagement {
    repositories {
        maven {
            url 'https://maven.aliyun.com/repository/gradle-plugin'
        }
    }
}
rootProject.name = 'demo'
// settings.gradle

依賴倉庫：

    id 'io.spring.dependency-management' version '1.0.9.RELEASE'
    id 'java'
}

      maven { url 'https://maven.aliyun.com/nexus/content/repositories/google' }
      maven { url 'https://maven.aliyun.com/nexus/content/repositories/jcenter'}
