无法运行项目 - Android Studio 2.0 Crashlytics 问题

我将 Android Studio 更新到 2.0 并尝试让即时运行正常工作。 Gradle 同步有效。 重建项目正在进行中。 尝试运行，失败:(。

我究竟做错了什么？

变量：

• io.fabric.tools:gradle:1.14.4

• com.android.tools.build:gradle:2.0.0-alpha1

• buildTools版本 23.0.2

Error:

FAILURE: Build failed with an exception. 
What went wrong: Could not determine the dependencies of task ':Application:crashlyticsStoreDeobsDebug'. 
Task with path 'dexDebug' not found in project ':Application'. 
Try:Run with --info or --debug option to get more log output.

堆栈跟踪：

我遇到了同样的问题并尝试了很多方法但没有成功。 我发现的唯一解决方案是从任何 gradle 文件（基本上是从存储库和编译部分）中删除对 Fabric 或 crashlytics 的所有引用，然后通过 Fabric 插件重新添加它们。

我认为存在一些重复且不兼容的内容。

例如我有（以下一些行位于项目 gradle 中，其他行位于模块 gradle 中）

repositories {
    jcenter()
    maven { url 'http://download.crashlytics.com/maven' }
    maven { url 'https://maven.fabric.io/public' }
}
dependencies {
    classpath 'com.android.tools.build:gradle:2.0.0-alpha1'
    classpath 'com.crashlytics.tools.gradle:crashlytics-gradle:1.16.0'
    classpath 'io.fabric.tools:gradle:1.20.0'
}

现在我只有

repositories {
    jcenter()
    maven { url 'https://maven.fabric.io/public' }
}
dependencies {
    classpath 'com.android.tools.build:gradle:2.0.0-alpha1'
    classpath 'io.fabric.tools:gradle:1.20.0'
}
