java - 发生评估根项目> com.android.application找不到插件

Question

下载了一个有问题的android项目，我在gradle文件中有这个问题...

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.21.5'
    }
}
apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

但是我得到了错误。
Plugin with id 'com.android.application' not found
任何想法是什么问题？

尝试在根gradle中:

buildscript {
  repositories {
    jcenter()
    maven { url 'https://maven.fabric.io/public' }
  }
  dependencies {
    // 2.1.2 is newest  plugin but required studio >=  2.1
    classpath 'com.android.tools.build:gradle:1.5.0' 
    // The Fabric Gradle plugin uses an open ended version to react
    // quickly to Android tooling updates
    classpath 'io.fabric.tools:gradle:1.+'
  }
}

repositories {
    jcenter()
    maven { url 'https://maven.fabric.io/public' }
}

在应用程序或lib gradle中:

apply plugin: 'com.android.application'
//Put Fabric plugin after Android plugin
apply plugin: 'io.fabric'

Fabric 版本插件请参见:
https://s3.amazonaws.com/fabric-artifacts/repo/io/fabric/tools/gradle/maven-metadata.xml

<latest>1.21.5</latest>
<release>1.21.6</release>

顺便说一句，不要在库/类中使用加号，这会减慢构建过程:而是 classpath'io.fabric.tools:gradle:1.+' use-> classpath'io.fabric.tools:gradle:1.21 .6'
