找不到Gradle DSL方法：“ getMavenAccessKey（）”

Question

当我构建Project时，Android Studio会显示此问题： 找不到Gradle DSL方法：“ getMavenAccessKey（）” 可能的原因： 项目'videoDownloader'可能正在使用不包含该方法的Android Gradle插件版本（例如，在1.1.0中添加了'testCompile'）。

build.gradle（Module：videokit）

这是所有错误信息：

Gradle DSL method not found: 'getMavenAccessKey()'
Possible causes:
The project 'videoDownloader' may be using a version of the Android Gradle plug-in that does not contain the method (e.g. 'testCompile' was added in 1.1.0).
Upgrade plugin to version 3.4.1 and sync project

The project 'videoDownloader' may be using a version of Gradle that does not contain the method.
Open Gradle wrapper file

The build file may be missing a Gradle plugin.
Apply Gradle plugin
