业务需求：1，windows上执行脚本 2，先检查是否运行着A.jar 3，如果有运行着的A.jar,则结束该任务，再重新运行A.jar，并修改进程名； 4，如果没有运行着A.jar，则直接运行A.jar并修改进程名 5，并检查运行状态和结束状态是否正常 请给一个windows脚本

以下是一个可能的Windows脚本，可以满足您的需求：

@echo off

set PROCESS_NAME=A.jar
set NEW_PROCESS_NAME=A_modified.jar

REM 检查是否有运行着的A.jar
tasklist /FI "IMAGENAME eq %PROCESS_NAME%" | findstr /i %PROCESS_NAME% >nul
if %errorlevel% neq 1 (
    echo A.jar is running. Stopping the task...

    REM 结束该任务
    taskkill /f /im %PROCESS_NAME%

    REM 等待一段时间，确保进程已经结束
    timeout /t 5 /nobreak >nul
)

REM 运行A.jar并修改进程名
echo Starting A.jar...
start "" "%~dp0%PROCESS_NAME%" && (
    timeout /t 5 /nobreak >nul
    wmic process where name="%PROCESS_NAME%" CALL setpriority "high priority"
    wmic process where name="%PROCESS_NAME%" CALL setpriority "idle"
    wmic process where name="%PROCESS_NAME%" CALL setpriority "high priority"
    wmic process where name="%PROCESS_NAME%" CALL setpriority "idle"
    wmic process where name="%PROCESS_NAME%" CALL setpriority "high priority"
    wmic process where name="%PROCESS_NAME%" CALL setpriority "idle"
    wmic process where name="%PROCESS_NAME%" CALL setpriority "high priority"
    wmic process where name="%PROCESS_NAME%" CALL setpriority "idle"
)

REM 修改进程名
echo Modifying process name...
for /f "tokens=2 delims=," %%a in ('wmic process where "name='%PROCESS_NAME%'" get processid^,status /format:csv') do (
    set status=%%a
    goto :next
)
:next
if "%status%"=="Running" (
    for /f "tokens=2 delims=," %%a in ('wmic process where "name='%PROCESS_NAME%'" get processid^,executablepath /format:csv') do (
        set path=%%a
        goto :rename
    )
    :rename
    set newpath=%path:%PROCESS_NAME%=%NEW_PROCESS_NAME%
    wmic process where "name='%PROCESS_NAME%'" CALL update "%newpath%"
)

REM 检查运行状态和结束状态是否正常
echo Checking status...
timeout /t 5 /nobreak >nul
tasklist /FI "IMAGENAME eq %NEW_PROCESS_NAME%" | findstr /i %NEW_PROCESS_NAME% >nul
if %errorlevel% neq 0 (
    echo Failed to start A.jar.
    pause
    exit /b 1
)

echo Checking exit status...
timeout /t 5 /nobreak >nul
tasklist /FI "IMAGENAME eq %NEW_PROCESS_NAME%" | findstr /i %NEW_PROCESS_NAME% >nul
if %errorlevel% equ 0 (
    echo A.jar is still running.
    pause
    exit /b 1
)

echo A.jar has exited successfully.
pause
exit /b 0
