How to reference system ProGuard binary in build.gradle?

I noticed that running gradle assembleRelease calls upon an outdated ProGuard version as can be seen from the shell output:

$ gradle assembleRelease
Relying on packaging to define the extension of the main artifact has been \
  deprecated and is scheduled to be removed in Gradle 2.0

BUILD SUCCESSFUL

Total time: 15.703 secs

I use the following configuration in my build.gradle:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.6.+'
    }
}

apply plugin: 'android'

repositories {
    mavenCentral()
}

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.0"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 19
    }

    buildTypes {
        release {
            runProguard true
            proguardFile 'proguard-project.txt'
        }
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:19.0.0'
    compile 'com.android.support:support-v4:19.0.0'
    compile 'com.google.android.gms:play-services:3.1.36'
}

How can I point gradle to a newer version of ProGuard which might be available from the PATH, e.g. /usr/local/bin/proguard?

An alternative solution is to reference the desired version as follows:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.6.+'
        classpath 'net.sf.proguard:proguard-gradle:4.10'
    }
}
...

What is your setup?

The official Proguard doc shows how you can point to proguard in the build.gradle. See here

As per the Proguard manual you can do the below to point to a proguard binary,

buildscript {
    repositories {
        flatDir dirs: '/usr/local/java/proguard/lib'
    }
    dependencies {
        classpath ':proguard'
    }
}

I think this might cause problems with the proguard version that comes shipped with the android SDK. Not tried yet!!
