Re: ant and external jars relative to an environment variable

I assume you're using one of the ant-based projects in Xcode, right? You should not be trying to build via ant using an Xcode Java project.

Now that that's out of the way, in your Target(s), do you have the necessary environment variables defined? This would be in the Build Settings section of your target, e.g.:

MYPROJECT		/Users/you/path/to/my/project/stuff

I have several external jars that are located relative to a directory specified by an environment variable $MYPROJECT. I need to construct a classpath within my build.xml so that javac can compile my project. I do not want to include the external jars in my project - just reference them. It seemed pretty straightforward but I can't seem to get it to work under XCode. I have had some success from the Terminal though. What's the recommended way to do this?

Here's my compile target:

    <target name="compile" description="Compile code">
        <mkdir dir="${bin}"/>
        <mkdir dir="${lib}"/>
        <javac srcdir="${src}" destdir="${bin}"
               source="1.5" target="1.5"
               includeAntRuntime="no"
			   classpath="${myclasspath}"
			   debug="${compile.debug}">
		</javac>
    </target>


One thing I discovered is that a "property" value does not evaluate/ expand other environmental variables. It expects a constant.

e.g.
<property name="myclasspath" value=".:${env. MYPROJECT}/endorsed/ xercesImpl.jar:${env. MYPROJECT}/endorsed/jdom.jar"/>

I also tried :

<path id="myclasspath">
<pathelement path=".:${env. MYPROJECT}/endorsed/xercesImpl.jar:$ {env. MYPROJECT}/endorsed/jdom.jar"/>
</path>

and then used classpathref="myclasspath" in the javac task but that didn't work either. I also tried using FileSets.

What am I missing?
