尝试在云中部署我们的服务我遇到了两个传递依赖项无法下载的问题:

Welcome to Gradle 6.7.1!

我可以在网络和 stackoverflow 上找到的大多数解决方案都集中在添加一个新的 confluent.io gradle 存储库:

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

我尝试了 http 和 https。两者都没有改变云中的任何东西。

我尝试将传递依赖项直接添加到项目 gradle。这种方法也没有成功:


    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?

【解决方案1】:

云中的防火墙阻止了请求。出于某种原因,它们没有被归类为http,而是被归类为confluent 请求,防火墙不知道,因此被阻止。针对 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这个问题。
