solution for exit code problems in maven1

[Baz <br...@gmail.com>]

I've added this as a comment on
http://jira.codehaus.org/browse/CONTINUUM-413 but since several people
are having the problem, I thought I'd tell the list.

The correct answer is, change continuum's run.bat to begin:
@echo off
set MAVEN_TERMINATE_CMD=on

then add this one line to the end of maven.bat:
if "%MAVEN_TERMINATE_CMD%" == "on" exit %ERRORLEVEL%

I've tested this solution, it works under winXP, maven 1.0.2.

Hope this helps,
Baz

The environment of the parent process is carried through to child
processes: you define it in run.bat so it's in java.exe's environment,
and hence in the environment of processes java spawns, and so on.

That's actually semi-sensible. Its the behaviour of 'exit' in batch
files that's just freaky. In *nix systems, executing a shell script
happens in a separate process. Not so in windows, executing a batch
file from the command line is more akin to a function call. Hence the
difference between 'exit' (exits the process, ie cmd.exe, with a real
return code) and 'exit /B' (pop back up to the calling batch, setting
ERRORLEVEL, don't set the error code).

It's just nuts. In the absence of a sensible 'exit', we need something
like 'isatty()' to tell us which way to call it, but AFAIK you can't
get this info.

Isn't windows great?

Cheers,

I'm surprised that it works if you define MAVEN_TERMINATE_CMD in run.bat
