Re: Need of serious help (almost there!)

[baleineca]

I'm no batch file expert either and I thought it's was strange, but 
here's what happens with the original line `if "%OS%"=="Windows_NT" SET 
M2_HOME=%~dps0\..`:

M2_HOME = C:\PROGRA~1\MAVEN-~1.0-A\bin\m2.bat\..
which points to bin.
I also thought it was supposed to return the directory, but it's 
returning the file (this is happening on win2000, I've seen batch 
commands behave differently on various win versions, so maybe it's 
correct on winXP?)

Hence my correction to go up one more from bin...

Can you explain this to me? I'm no .bat file wizard, but I thought I
tested this.
IIRC, %~dps0 is the (d)rive and (p)ath of the batch file (%0), using a
(s)hort name.
So M2_HOME=c:\maven2\bin\..
which is correct. I thought yours would give c:\ in that case.
Thanks...
