kafka运行找不到或无法加载主类 Files\Java\jdk1.8.0_131\lib\dt.jar;C:\Program

最近在研究Flink+kafka解决方案，

kafka的安装首先需要安装zookeeper，在安装zookeeper是报错找不到或无法加载主类 Files\Java\jdk1.8.0_131\lib\dt.jar;C:\Program

　打开zookeeper-server-start.bat

IF [%1] EQU [] (
	echo USAGE: %0 zookeeper.properties
	EXIT /B 1
)

SetLocal
IF ["%KAFKA_LOG4J_OPTS%"] EQU [""] (
    set KAFKA_LOG4J_OPTS=-Dlog4j.configuration=file:%~dp0../../config/log4j.properties
)
IF ["%KAFKA_HEAP_OPTS%"] EQU [""] (
    set KAFKA_HEAP_OPTS=-Xmx512M -Xms512M
)
"%~dp0kafka-run-class.bat" org.apache.zookeeper.server.quorum.QuorumPeerMain %*
EndLocal

　　发现使用的事kafka-run-class.bat

　　紧接着打开kafka-run-class.bat

　　找到179行

set COMMAND=%JAVA% %KAFKA_HEAP_OPTS% %KAFKA_JVM_PERFORMANCE_OPTS% %KAFKA_JMX_OPTS% %KAFKA_LOG4J_OPTS% -cp %CLASSPATH% %KAFKA_OPTS% %*
rem echo.
rem echo %COMMAND%
rem echo.
%COMMAND%

　　看到了CLASSPATH，难道我的CLASSPATH配置有问题，重新检查一下，还是有问题，于是找文档和百度

set COMMAND=%JAVA% %KAFKA_HEAP_OPTS% %KAFKA_JVM_PERFORMANCE_OPTS% %KAFKA_JMX_OPTS% %KAFKA_LOG4J_OPTS% -cp "%CLASSPATH%" %KAFKA_OPTS% %*
rem echo.
rem echo %COMMAND%
rem echo.
%COMMAND%
