How to access ext variables in Gradle

Question

I am trying to get the variable defined in a 3rd party library (fabric) to do a condition based on whether Crashlytics is enabled or not.

ext.enableCrashlytics = true

http://support.crashlytics.com/knowledgebase/articles/202938-gradle The variable can be configured in buildTypes or in flavors but I can't find a way to access it elsewhere in my build.gradle

I tried several things without any luck.

allprojects.getProperties().get("enableCrashlytics")
project.enableCrashlytics
project.ext.enableCrashlytics
allProjects.ext.enableCrashlytics

Anyone tried that before? The context I'm trying to do this is to write the fabric.properties file based on if it is enabled or not.

android.applicationVariants.all { variant ->
  ...
  //create fabric.properties
  ...
}

You can define a property in your top-level build.gradle:

ext {
  myproperty = 12
}

Or an array:

ext {

    myarray = [
            name0     : "xx",
            name1     : "xx"
   ]
}

Then in each module you can use somenthig like:

rootProject.ext.myproperty
rootProject.ext.myarray.name0
