如何通过 .bat 文件将参数传递给另一个 Java 程序？

Question

I have a question regarding the evaluation of my code using a evaluator program by accessing it via a batch file. I have pasted the batch file code below.

@if "%DEBUG%" == "" @echo off
if "%OS%"=="Windows_NT" setlocal

set DIRNAME=%~dp0
if "%DIRNAME%" == "" set DIRNAME=.
set APP_BASE_NAME=%~n0
set APP_HOME=%DIRNAME%..

@rem Add default JVM options here. You can also use JAVA_OPTS and TASK_SMALLEST_POLYGON_EVALUATOR_OPTS to pass JVM options to this script.
set DEFAULT_JVM_OPTS=

@rem Find java.exe
if defined JAVA_HOME goto findJavaFromJavaHome

set JAVA_EXE=java.exe
echo %JAVA_EXE%
%JAVA_EXE% -version >NUL 2>&1
if "%ERRORLEVEL%" == "0" goto init

echo.
echo ERROR: JAVA_HOME is not set and no 'java' command could be found in your PATH.
echo.
echo Please set the JAVA_HOME variable in your environment to match the
echo location of your Java installation.

goto fail

:findJavaFromJavaHome
set JAVA_HOME=%JAVA_HOME:"=%
echo %JAVA_HOME%
set JAVA_EXE=%JAVA_HOME%/bin/java.exe

if exist "%JAVA_EXE%" goto init

echo.
echo ERROR: JAVA_HOME is set to an invalid directory: %JAVA_HOME%
echo.
echo Please set the JAVA_HOME variable in your environment to match the
echo location of your Java installation.

goto fail

There is an evaluator which needs to evaluate my code. I would like to know how to pass an argument to this batch file. I tried to input in the argument a location of my .jar file but I get an error of

java.io.IOException: Cannot run program "D:\\Programs\\Java\\programming\\Polygon\\bin\\testerexec.jar": CreateProcess error=193, %1 is not a valid Win32 application

ERROR com.simscale.util.Util$ - unexpected exception in thread java.io.IOException: Cannot run program "java -jar "D:\\New folder\\task-smallest-polygon-evaluator\\bin\\testerexec3.jar"": CreateProcess error=2, The system cannot find the file specified

I have tried 2 kinds of arguments in the input, but none of them seem to work

An evaluator program is supplied. This program receives one positional argument, which is the executable file (entry point for the target program – your program).

The positional argument I am passing is generating an error. Could somebody help me on how to pass this positional argument? What inputs must be given in the bat file?

Try installing it as a window service first and run the service.

download the nssm using this link: https://nssm.cc/release/nssm-2.24.zip Then, install your .jar file as a windows service first. Sample code to install as a service: nssm install serviceName url-to-java-exec url-to-Jar-file

Hope this is helpful
