讓你的 android project 相容於 gradle 1.7 & 1.8

build.gradle

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        if (gradle.gradleVersion.startsWith("1.8")) {
            classpath 'com.android.tools.build:gradle:0.6.0'
        } else {
            classpath 'com.android.tools.build:gradle:0.5.6'
        }
    }
}

task wrapper(type: Wrapper) {
    gradleVersion = '1.7'
}
