找不到Gradle DSL方法：“ android()”

Gradle DSL method not found: 'android()'

我正在使用android studio 1.4
gradle版本2.4
android插件版本1.3.0

Error:(7, 0) Gradle DSL method not found: 'android()'

Possible causes:

The project 'Up_13_7_2015' may be using a
version of Gradle that does not contain the method. Gradle settings

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

Build.gradle文件是

在项目级build.gradle文件中查找错误并进行修复。

就我而言，当我向项目中添加新的库模块时，问题就出现了。我的build.gradle看起来像这样：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
ext.kotlin_version = '1.3.50' '1.3.31'
repositories {
google()
jcenter()

}
dependencies {
classpath 'com.android.tools.build:gradle:3.5.0'
classpath"org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}

allprojects {
repositories {
google()
jcenter()

}
}

task clean(type: Delete) {
delete rootProject.buildDir
}

如您所见，这行是不正确的：

1	ext.kotlin_version = '1.3.50' '1.3.31'

我将其更改为

1	ext.kotlin_version = '1.3.50'

而且我不再收到错误了。

你需要

1	apply plugin: 'com.android.application'

在您的应用模块build.gradle文件顶部，在android { }之前。
