如何在Gradle中访问ext变量 [英] How to access ext variables in Gradle

问题描述

我试图获取在第3方库（结构）中定义的变量，以根据是否启用了Crashlytics做一个条件。

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
可以在以下位置配置变量buildTypes或风味，但在build.gradle中找不到其他方法。

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

我尝试了几件事没有运气。

I tried several things without any luck.

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

有人尝试过吗？我正在尝试执行的上下文是根据是否启用来写入fabric.properties文件。

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
  ...
}

推荐答案

您可以在顶级 build.gradle ：

ext {
  myproperty = 12
}

或一个数组：

ext {

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

然后在每个模块中都可以使用somenthig，例如：

Then in each module you can use somenthig like:

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