android-gradle-plugin - 使用 Groovy 插件 DSL 的 Crashlytics 的 Fabric 插件构建 Gradle

Question

我使用 Crashlytics 和 Crashlytics gradle 文档中记录的标准 Gradle 设置对 Android 应用程序进行了完美的 gradle 构建。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 和 apply plugin 子句，并将它们替换为 gradle supports and Kotlin requires 的 plugins 子句。我已经看到纯 kotlin 项目成功地做到了这一点，但无法使用 Groovy 来完成这个中间/准备步骤。插件子句出现此错误:

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 Gradle 插件门户中不存在 Fabric 插件(还没有？)，我正在使用这个 settings.gradle，这部分似乎工作正常。它发现 Fabric 没有问题:

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'

switch 中是否存在 com.android.application 似乎无关紧要，两种方式的行为都是相同的。

应用程序的 build.gradle 中相应的插件子句如下所示:

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

如果有用，构建中同步尝试的完整异常堆栈如下所示:

出于某种原因，Crashlytics 插件无法以这种方式查看 Android 应用程序插件。任何人都知道我做错了什么，或者这种使用 plugins 子句是否应该与 Fabric 插件一起使用？在此先感谢您的帮助

对于遇到此问题的其他人，简单的解决方法是跳过在 plugins{} block 中应用插件，而是稍后在构建脚本中应用它(甚至紧跟在 plugins {} block 没问题):

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