    goto :eof
    :winnt
    set DIRNAME=.

    set PROGNAME=configwizard.bat
    if "%OS%" == "Windows_NT" set PROGNAME=%~nx0%
    pushd %DIRNAME%..

     "Java" %CW_CMD%
      pause

thanks in advance

Answer 1

除了我的注释，尝试替换

"Java" %CW_CMD%

call %CW_CMD%

由于您已经在CW_CMD中设置了路径为java.exe，因此不需要第一个"Java"

Answer 2

你应该删除"Java" %CW_CMD%中的"Java"

%CW_CMD%
pause

你还应该删除

行

set JAVA_HOME=%JAVA_HOME%

Answer 3

您是否在环境变量路径中提到了com.xyz.yyz.DatabaseComparator ?如果没有，请在路径变量中注明，并尝试执行批处理文件
