Java Kafka Connect-文件源连接器错误

我正在玩联合平台/Kafka Connect和类似的东西，我想举几个例子

我从一开始就遵循quickstart。这意味着：

安装汇流平台（v3.2.1）

运行Zookeeper、Kafka代理和模式寄存器

读取文件数据的运行示例（witk Kafka Connect）

我运行了这个命令（编号3）：

但是得到了这个结果：

在第67行的

ConnectStandalone.java

文件中是这样的：

Time=Time.SYSTEM，但我不知道，为什么它会导致任何错误。有什么想法吗？我错过了什么重要的事情吗

我的工作环境：


Hortonworks沙箱[HDP 2.5.0.0-1245]
CentOS 6.8版
Java:openjdk版本“1.8.0_121”
我在第67行的“ConnectStandalone.java文件”中遇到了相同的问题：Time=Time.SYSTEM“

可能是OpenTSDB连接器依赖于kafka-clients-versionA.jar的版本不同于./libs下的kafka-clients-versionB.jar。
它与此有关。当我在我的类路径中包含JAR文件时（根据说明），我得到的两个输出相同（对于文件源连接器和OpenTSDB连接器）。未设置时，我可以运行文件源连接器，但不能运行OpenTSDB one（未找到连接器，因为它不在类路径中）。不知道如何正确设置..FWIW，HDP已经有了
connect standalone
script这正是问题所在，这都是版本的问题。最后，我用build.sbt文件中定义的不同版本构建了这个连接器，它很有帮助！谢谢
