    Summary: maven Linux shell script incorrectly quotes arguments it passes through to Java

Environment: Linux (in my case, Mandrake 9.1)

Description:
If I want to pass a Java property with a space in it through to my goal,
for example,

maven -e "-Dminestar.release=stable potatoes" zip

maven incorrectly quotes the parameters when passing them to Java resulting in:

BUILD FAILED
Goal "potatoes" does not exist in this project.

HERE'S THE FIX:

Edit the maven shell script. Down the bottom are two lines which say:

    $MAIN_CLASS $@

Change them to

    $MAIN_CLASS "$@"

This tells the shell to quote parameters individually. The bash manual says:

       @      Expands  to  the positional parameters, starting from one.  When
              the  expansion  occurs  within  double  quotes,  each  parameter
              expands to a separate word.  That is, "$@" is equivalent to "$1"
              "$2" ...  When there are no positional parameters, "$@"  and  $@
              expand to nothing (i.e., they are removed).

It took me ages to find this trick for our own system, I know it's confusing as hell.
