jdbc - Kafka Connect - NoClassDefFoundError：无法初始化类 org.apache.calcite.jdbc.Driver

问题描述

使用 Confluent 发布新的源连接器时：

curl -X POST -H "Content-Type: application/json" -d @db2-source-conn-incr.json http://localhost:8083/connectors

我收到这条消息：

<html>
<head>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8"/>
<title>Error 500 Request failed.</title>
</head>
<body><h2>HTTP ERROR 500</h2>
<p>Problem accessing /connectors. Reason:
<pre>    Request failed.</pre></p><hr><a href="http://eclipse.org/jetty">Powered by Jetty:// 9.4.11.v20180605</a><hr/>

</body>
</html>

我已经重新启动了我的服务，但是在尝试创建新的连接器时得到了这个。

这是日志文件消息：
