Java gradle kafka-avro-serializer 和 kafka-schema-registry-client 在部署管道中下載失敗

Question

嘗試在雲中部署我們的服務時，我遇到了兩個傳遞依賴項無法下載並出現錯誤的問題：

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)

我可以在 web 和 stackoverflow 中找到的大多數分辨率都集中在添加新的 confluent.io gradle 存儲庫：

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

我嘗試了 http 和 https。 兩者都沒有改變雲中的任何東西。

我嘗試將傳遞依賴項直接添加到項目 gradle。 這種方法也沒有成功：

    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'

可能是什么問題？ 如何最好地解決這個問題？

Answer 1

雲中的防火牆阻止了請求。 由於某種原因，它們沒有被歸類為http ，而是被歸類為confluent請求，防火牆不知道，因此被阻止。 針對 k8s 中的“融合”應用程序。 我不知道這個應用程序來自哪里，但是......啟用這些請求解決了這個問題。
