proguardFile getDefaultDexGuardFile('dexguard-release.pro') no longer works
<p>When using DexGuard with android studio, there's a line we have always needed to include for our release builds, and that's</p>

<pre><code>proguardFile getDefaultDexGuardFile('dexguard-release.pro')
</code></pre>

<p>I have never been able to figure out how to change the path that getDefaultDexGuardFile looks in for dexguard-release.pro, but so far it has always been correctly searching in the /lib folder of my DexGuard folder.</p>

<p>Even 2 days ago, with Android Studio 2.0.0 it was fine. Today, I tried building the release version of another project, where it had found dexguard-release.pro before (with Android Studio 1.5.0 earlier on), and now it gives</p>

<pre><code>Warning:Exception while processing task java.io.FileNotFoundException: /lib/dexguard-release.pro (No such file or directory)
</code></pre>

<p>How am I supposed to fix this? There appears to be no documentation through google search (or the official DexGuard docs) that explain the workings of getDefaultDexGuardFile .. how it decides where to look, or how to change it. Furthermore, the warning message is not very helpful, giving what appears to be a partial path /lib/dexguard-release.pro rather than the full path of the actual place it is now trying to find dexguard-release.pro</p>

<p>If somebody could tell me how I could gain some control of the path that getDefaultDexGuardFile is searching .. ?</p>
