Can't run "preverify.exe" using Ant's task

Question

I am having trouble getting my Ant script (for BlackBerry build) to run the preverify.exe command & pass the correct parameters to it.

In the command prompt (Windows 7), this works 100% - the parameters as given work properly:

preverify -verbose -classpath C:\development\tools\bb-jde\jde5.0\components\lib\net_rim_api.jar -d build\classes\preverified build\classes\preverified build\classes\unverified

I tried to put this into my Ant script using the following target - trying to use the same parameters:

<target name="preverify">
    <mkdir dir="${dest.dir}/classes/preverified" />
    <exec executable="${jde.home}/bin/preverify">
        <arg value="-verbose" />
        <arg value="-classpath C:\development\tools\bb-jde\jde5.0\components\lib\net_rim_api.jar" />
        <arg value="-d build\classes\preverified" />
        <arg value="build\classes\unverified" />
    </exec>
</target>

This does not work. I get the following error:

Illegal option 
-classpath C:\development\tools\bb-jde\jde5.0\components\lib\net_rim_api.jar

this classpath was perfectly acceptable from the command line (often java commands accept JAR files as directories, since they are basically ZIP files).

How can I get Ant to send the correct parameters to this command, as in the command line version? There must be something about exec that I'm missing?

Here is the full Ant output from running this target in verbose mode, if it helps:

This doesn't look like an ANT issue. The error message is being returned by the preverify command, proving that ANT is executing it...

I don't understand what this command is supposed to be doing, however the usage message gives a hint as to the root cause:

[exec] Usage: preverify [options] classnames|dirnames ...
[exec]
[exec] where options include:
[exec]    -classpath     <directories separated by ';'>
[exec]                   Directories in which to look for classes

You haven't specified a list of directories as the "classpath" parameter.... You've supplied a jar file. Is the command able support jar files?

thx it was a problem with the parameters containing spaces in them. Splitting the params over multiple lines fixed the issue. — Richard Le Mesurier, May 24 '12 at 08:06

The way you are passing the parameters is incorrect. The space between the -classpath tag, and the JAR name is not allowed.

You must break that line (and the -d below it) onto 2 lines. This works:

    <exec executable="${jde.home}/bin/preverify">
        <arg value="-verbose" />
        <!-- classpath to the RIM api -->
        <arg value="-classpath" />
        <arg value="C:\development\tools\bb-jde\jde5.0\components\lib\net_rim_api.jar" />
        <!-- destination folder -->
        <arg value="-d" />
        <arg value="build\classes\preverified" />
        <!-- source folder -->
        <arg value="build\classes\unverified" />
    </exec>

I solved this problem by including the jdk\bin directory path in environment variable PATH.
