I did some work on this problem I have with command line arguments:

Now, my task constructs the correct escaped String and when I use this
on the windows command line it works without problems. However, when I
use this...
private static final String HS_CMD_LINE = "helpstudio2.exe";
[...]
cmd.setExecutable(path + HS_CMD_LINE);
cmd.addArguments((String[]) lArgs.toArray(new
String[lArgs.size()]));
Output of cmd.toString():
C:\Programme\Innovasys\HelpStudio2\bin\helpstudio2.exe /s
/bk="te st" "C:\1temp\helpstudioant\te st\test.hsp"
...HelpStudio throws an exception. This probably means, that /bk="te
st" was converted to '/bk="te st"' so HelpStudio thinks that the
project file is used twice.
I´m in contact with Innovasys to see if they can change the way
command line arguments are used in HelpStudio. Though, I would like to
know if there is a way to solve this problem by myself or if there is
no such way.
Any suggestions are welcome =)
Lars
