        The Kafka REST Proxy provides a RESTful interface to a Kafka cluster, making it easy to
        produce and consume messages, view the state of the cluster, and perform administrative
        actions without using the native Kafka protocol or clients.

Answer 1

为了从主分支构建任何合流项目，您必须构建其父依赖项。您在可下载位置找不到快照

这意味着查看Kafka源代码，使用Gradle安装其当前快照，然后是Confluent common library，然后是Confluent Rest utils，然后是Schema Registry (用于Avro转换器)，最后是，最后是。

如果您只想运行REST代理，那么下载最新的Confluent平台并配置rest代理配置文件，使其指向任何现有的Kafka代理

Answer 2

另一种解决方案是构建一个发布版本。

您可以通过运行以下命令来查找发行版

git tag --list

选择一个标签t(例如v5.2.2)，然后运行

git checkout <t>

然后运行

man clean package
