Mxmlc error

Question

I'm trying to set up an ant buildfile that will compile a bunch of small Actionscript projects and do some other small tasks. My problem is with mxmlc when specifying the output SWF file's location.
The relevant stuff from build.xml looks like this:
<exec executable="C:/Program Files (x86)/Adobe/Adobe Flash Builder 4/sdks/3.5.0/bin/mxmlc.exe"
               failonerror="true">
               <arg value="${minisrc}/movie/src/Movie.as"/>
               <arg value="-incremental"/>
               <arg value="-debug=true"/>
               <arg value="-load-config+=${MINIGAME_CONFIG}"/>
               <arg value="-output ${minidist}/blah/Movie.swf"/>
          </exec>
That last argument is what is giving me problems. If I leave it out, mxmlc runs fine but does not place the SWF where I want it. If I try to run it like the above then I get:
command line: Error: unknown configuration variable 'output D:\giantpath/../../dist/blah/Movie.swf'
I've tried putting the path in double quotes and single quotes but nothing seems to work.
I am actually doing the above because of another error with ant/flex/fb/mxmlc:
I would like to use this XML to run mxmlc:
<mxmlc file="${minisrc}/movie/src/Movie.as" output="${minidist}/movie/Movie.swf"
               fork="true" maxmemory="512m" incremental="false" debug="true">
               <load-config filename="${MINIGAME_CONFIG}"/>
          </mxmlc>
However, that gives me the following error:
    [mxmlc] java.lang.NoClassDefFoundError: flex2/tools/Compiler
    [mxmlc] Caused by: java.lang.ClassNotFoundException: flex2.tools.Compiler
    [mxmlc]      at java.net.URLClassLoader$1.run(Unknown Source)

    [mxmlc] Could not find the main class: flex2.tools.Compiler.  Program will exit.

I did some research and set fork to false, but then it is even worse, giving me:

So, it'd be great if anyone could help me getting one of these two methods to work.

Thank you for the response,
I should have mentioned in my first post that I am running Windows 7 64-bit. Also, I was defining FLEX_HOME in this manner:
<property file="../build.properties"/>
And the contents of that file are:
FLEX_HOME=C:/Program Files (x86)/Adobe/Adobe Flash Builder 4/sdks/3.5.0
But I get the NoClassDefFoundError.
If I define FLEX_HOME inside build.xml with a property tag like this:
<property name="FLEX_HOME" location="C:/Program Files (x86)/Adobe/Adobe Flash Builder 4/sdks/3.5.0"/>
I get the same error, NoClassDefFoundError.
