我试图在Ubuntu 18.04（这是一个VMware虚拟机）中使用MANASVI GUPTA article从源代码构建Apache Kafka。在文章的最后一步，当我按下运行按钮时，出现以下错误：

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation

答案 0 :(得分：1)
好像您是直接从Intellij运行代码
您可以忽略SLF4J警告，但是如果未启用日志库（例如默认的log4j），您将看不到任何控制台输出。
这就是为什么您要运行提供的kafka-server-start脚本而不是直接运行服务器类的main方法的原因。
如果要在IDE中单步执行代码，则可以使用远程调试来做到这一点
如果Gradle成功构建代码，则不会出现任何构建错误
