How to abstract ant-contrib cross-platform?

Question

Is there a preferred method for calling ant-contrib from your build scripts in such a way that platform differences won't get in the way?

I originally prepared my build from Ubuntu, but when running on OSX with ant-contrib installed via Homebrew, I end up with errors. Seemingly because the contrib jar can't be found.

For people using Homebrew, please be sure to look at this github issue: https://github.com/Homebrew/homebrew/issues/41469 — Alexander Trauzzi, Jul 08 '15 at 04:43

The preferred way to install Ant-Contrib is mentioned in this page:

Either install it under the lib folder of the Ant installation, and just import it using:
```
<taskdef resource="net/sf/antcontrib/antlib.xml"/>
```

Save the Jar file in a known location, perhaps relative to the buildfile, and specify its path:

<taskdef resource="net/sf/antcontrib/antlib.xml">
  <classpath>
    <pathelement location="path_to_ant_contrib_jar"/>
  </classpath>
</taskdef>
