Java gradle kafka-avro-serializer 和 kafka-schema-registry-client 在部署管道中下载失败

Question

尝试在云中部署我们的服务时，我遇到了无法下载两个传递依赖项的问题，并出现错误：

Welcome to Gradle 6.7.1!

我可以在网络上和此处的 Whosebug 上找到的大多数解决方案都以添加新的 confluent.io gradle 存储库为中心：

repositories {
    mavenCentral()
    maven {
        url "http://packages.confluent.io/maven/"
    }
}

http 和 https 我都试过了。两者都没有改变云中的任何内容。

我尝试将传递依赖项直接添加到项目 gradle。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'

可能是什么问题？如何最好地解决这个问题？

Answer 1

云中的防火墙阻止了请求。由于某种原因，它们没有被归类为 http，而是 confluent 请求，防火墙不知道这些请求，因此被阻止了。旨在 k8s 中的“融合”应用程序。我不知道这个应用程序来自哪里，但是...... 启用这些请求解决了问题。
