Import jar to lucene ant build script

I'm having trouble including the guava (http://code.google.com/p/guava-libraries/) library in my ant build script for lucene (lucene-3.5.0/build.xml). I'm trying to build the demo with the addition specified in the answer to this question: Detect duplicate English names

I have been able to successfully include the library in a standalone project

I get the error:

common.compile-core: [javac] Compiling 2 source files to /Users/seb/lucene-3.5.0/build/contrib/demo/classes/java [javac] /Users/seb/lucene-3.5.0/contrib/demo/src/java/org/apache/lucene/demo/NameDuplicateTests.java:17: package com.google.common.collect does not exist [javac] import com.google.common.collect.HashMultimap;

I have added the jar file to my classpath via

export CLASSPATH=$CLASSPATH:/$HOME/guava-10.0.1.jar

and made a similar change to /System/Library/Java/JavaConfig.plist

I have added the following to lucene-3.5.0/build.xml

<!-- Build classpath -->   <path id="classpath">
<pathelement location="${build.dir}/classes/java"/>
<pathelement location="$HOME/guava-10.0.1.jar"/>   </path>

I have the correct include statements in my java file, eg.

import com.google.common.collect.HashMultimap;

Thanks!

Check out the Ant docs.

You can access environment variables by passing them in using -D or the property task.

You may also define the full path to the library in the build file itself.

As it stands, your script has no idea what $HOME is.
