从命令行启动java应用程序时如何获取退出代码

Question

i made a program which returns an exitCode (from an ExitCodeGenerator). it works very well when i launch my application with command line like :

mvn spring-boot:run (i see my exitCode)

but how to get returned exitCode when i launch my application with this kind of command ?

java -jar target/<my-application-1.0-SNAPSHOT.jar>

thanks by advance

If you are using bash:

echo $?

If you are on windows:

echo %ERRORLEVEL%

Give you the exit value of the last run program. For example 0 often for a successful execution, everything else for (different) errors
