Kafka 可视化管理工具 CMAK 启动错误 -- 命令行太长问题解决

一、安装环境描述：

Kafka版本：kafka_2.13-2.8.1
cmak 版本：cmak-3.0.0.6
安装环境：windows 11

二、问题描述

当我们在命令行启动 cmak.bat 命令时，会报如下错误：

命令行太长

三、解决办法

修改 cmak.bat 文件，使用以下配置
修改 APP_CLASSPATH 路径，使用 * 代替原来的全路径

set "APP_CLASSPATH=%APP_LIB_DIR%\..\conf\;%APP_LIB_DIR%\*;"

修改后 cmak.bat 文件如下：

@REM cmak launcher script
@REM
@REM Environment:
@REM JAVA_HOME - location of a JDK home dir (optional if java on path)
@REM CFG_OPTS  - JVM options (optional)
@REM Configuration:
