使用Android Studio 3.3 Canary 11和gradle插件版本3.3.0-alpha11。当尝试同步gradle时,它会抛出以下错误

WARNING: API 'variant.getExternalNativeBuildTasks()' is obsolete and has been 
replaced with 'variant.getExternalNativeBuildProviders()'.
It will be removed at the end of 2019.
For more information, see https://d.android.com/r/tools/task-configuration-

单击错误将我引导到gradle文件中的这一行

applicationVariants.all { variant ->
            variant.outputs.all {
                outputFileName = "${variant.name}-${variant.versionName}.apk"
            }
        }

我到底需要改变什么?

我已经跳过了app/build中的一些常量和其他敏感信息。gradle文件。


当前回答

当我打开项目时,我按下了Android Studio右下角的Run migrations按钮。在没有注释掉Crashlytics依赖项的情况下,执行了一次迁移并解决了问题。

其他回答

构建日志打印如何调试这个,特别是你需要用-Pandroid.debug.obsoleteApi=true运行构建,这将打印对废弃API调用的堆栈跟踪,你将能够找出哪个插件/代码调用了它。

如果它最终是你的代码-使用新的提供者API(阅读惰性任务配置文档)

如果它来自其他插件-报告给他们的堆栈跟踪和警告消息,可能会提交一个补丁。在这种情况下,它与io有关。布料的问题。

EDIT

此问题已在Fabric 1.28.0中修复。在你的构建中。项目级Gradle,添加如下一行:

classpath 'io.fabric.tools:gradle:1.28.1'

以前的回答

这发生在我将Android Studio更新到3.3.0之后。应用插件:` io。“布料”是原因。关于这个问题,我已经向Firebase团队发送了一份错误报告。

你有三个选择:

等待下一个版本的Fabric插件发布。点击这里查看最新版本。 降级到Android Studio 3.2.1。 注释出io。织物插件。

在构建。你的应用模块的Gradle:

apply plugin: 'com.android.application'
// apply plugin: 'io.fabric' <== this plugin causes the error

但是,即使出现此错误,您仍然可以构建和运行项目。忽略它。

这个问题在今天发布的Fabric gradle插件1.28.0的最新版本中得到了修复。 在你的顶层build.gradle中包含这个:

buildscript {
// ... repositories, etc. ...

dependencies {
    // ...other dependencies ...
    **classpath 'io.fabric.tools:gradle:1.28.0'**
}

在应用程序构建中。Gradle,降级到这个稳定版本的Gradle:

classpath 'com.android.tools.build:gradle:3.2.1'

这发生在我将Android Studio更新到3.3之后,这是一个临时解决方案,直到他们修复它。


编辑: 你不需要降级你的Android Studio

这将修复错误: 在任务栏上单击“工具->Kotlin->在“项目”中配置Kotlin
