使用Fabric插件为具有groovy插件DSL的Crashlytics建立版本

Question

我使用Crashlytics和Crashlytics gradle文档中记录的标准Gradle设置，完美构建了一个Android应用程序。我正在使用Android Studio 3.2.1，Gradle 4.6 Android插件版本3.2.1，

作为稍后将构建脚本转换为Kotlin的准备工作的一部分，我删除了buildscript并应用了plugin子句，并用gradle support和Kotlin要求的plugins子句替换了它们。我已经看到纯Kotlin项目成功地做到了这一点，但是无法使用Groovy来完成这个中间/准备步骤。 plugins子句出现此错误：

Crashlytics was applied to a project without an Android plugin. Please make sure the Crashlytics plugin is applied after the appropriate Android plugin for your project.

由于Fabric插件在gradle插件门户中不存在（尚未？），因此我正在使用settings.gradle，这部分工作正常。它发现Fabric东西没问题：

pluginManagement {
    repositories {
        jcenter()
        google()
        maven { url "https://maven.google.com" }
        gradlePluginPortal()
        maven { url "https://maven.fabric.io/public" }
    }
    resolutionStrategy {
        eachPlugin {
            switch (requested.id.id) {
                case "com.android.application":
                    useModule("com.android.tools.build:gradle:${requested.version}")
                    break
                case "io.fabric":
                    useModule("io.fabric.tools:gradle:${requested.version}")
                    break
            }
        }
    }
}
include ':app'

开关中是否存在com.android.application情况似乎并不重要，两种方式的行为都相同。

应用程序的build.gradle中的相应插件子句如下：

plugins {
    id "com.android.application"
    id "signing"
    id "io.fabric" version "1.27.0"
}

如果有用，则来自构建中同步尝试的完整异常堆栈如下所示：

由于某种原因，Crashlytics插件无法以这种方式看到android应用程序插件。有人知道我在做什么错吗，或者对plugins子句的这种使用是否可以与Fabric插件一起使用？预先感谢您的任何帮助

对于其他遇到此问题的人，简单的解决方法是跳过在plugins{}块中应用该插件，而是稍后在构建脚本中应用它（即使紧随plugins{}块之后也可以）：

plugins {
    id("com.android.application")
    id("io.fabric") version("1.27.0") apply(false)
}
apply plugin: 'io.fabric'
