Fix Version/s: (was: before-1.1)
1.1-beta-1
> Allow arguments to be passed in a unified way to both mojos
> -----------------------------------------------------------
>
> Key: MEXEC-11
> URL: http://jira.codehaus.org/browse/MEXEC-11
> Project: Maven 2.x Exec Plugin
> Issue Type: Improvement
> Affects Versions: 1.0.2
> Environment: Windows XP SP2/Sun Java 1.5.09
> Reporter: Philippe Jacot
> Assignee: Jerome Lacoste
> Priority: Critical
> Fix For: 1.1-beta-1
>
> Attachments:
> patch_exec-maven-plugin_cmdline-args-handling-improved.patch,
> patch_exec-maven-plugin_cmdline-args-handling-improved_v2.patch

> The attached patch enhances the exec plugin to pass arguments via a system
> property to the exec and java mojo. When called with -Dexec.args=ARGUMENTS
> the argument string split into single parameters which are then passed to
> either the java or the exec mojo. Arguments can contain any number of
> arguments separated by spaces. The following characters are treated in a
> special way:
> ' ' (space) separates the different arguments
> i.e. -Dexec.args="There are 4 args" passes 4 arguments to the invoked program
> ' " ' (double quote) is used to to pass an argument that contains spaces
> i.e. -Dexec.args="\"A single argument\"" passes a single argument
> ' \ ' (backslash) is used to escape special characters.
> i.e. -Dexec.args="A\ single\ argument" passes a single argument
> When passing arguments through the commandline a user has to take care how
> his commandline escapes characters.
> Due to the way maven parses its arguments it is currently not possible to
> escape a double quote at the end of a word when usings mavens CLI, as maven
> assumes for a double quote followed by a space, that the current argument
> ends.
> As an example
> -Dexec.args="\"A single argument\" anotherone" will lead to an error (maven
> complains about anotherone" not being a proper lifecycle phase
> -Dexec.args="\"A single argume\"nt anotherone" works and leads to two
> arguments ("A single argument" and "anotherone")
> I hope this helps
> Cheers
