试图在云中部署我们的服务时，我遇到了两个可传递依赖项无法下载的问题，错误为：
Welcome to Gradle 6.7.1!
Here are the highlights of this release:
- File system watching is ready for production use
- Declare the version of Java your build requires
- Java 15 support
For more details see https://docs.gradle.org/6.7.1/release-notes.html
Starting a Gradle Daemon (subsequent builds will be faster)

我在网上和stackoverflow上能找到的大多数解决方案都是围绕添加一个新的confluent.io-gradle存储库：
repositories {
mavenCentral()
maven {
url "http://packages.confluent.io/maven/"
}
}
我同时尝试了http和https。两者都没有改变云中的任何东西。
我试图将可传递的依赖项直接添加到项目等级中。这种方法也不成功：
implementation group: 'io.confluent', name: 'kafka-avro-serializer', version: '5.3.2'
implementation group: 'io.confluent', name: 'kafka-schema-registry-client', version: '5.3.2'
问题可能是什么？如何最好地解决这个问题？
云中的防火墙正在阻止请求。出于某种原因，它们不是被归类为http，而是被归类为confluent请求，防火墙对此一无所知，因此正在阻止这些请求。针对"；汇合的"；应用程序。我不知道这个应用程序是从哪里来的，但是。。。启用这些请求解决了问题。
