android - Android Studio build.gradle 文件报错 Can't apply main & dependencies

Question

在将 Eclipse 项目转换为 Android Studio 项目后，build.gradle 中的 Android Studio 出现问题.

我花了2个多小时寻找解决方案，没有结果!!

build.gradle代码:

apply plugin: 'android'

 dependencies {
  compile fileTree(dir: 'libs', include: '*.jar')
 }

android {
compileSdkVersion 19
buildToolsVersion "17.0.0"

sourceSets {
    main {
        manifest.srcFile 'AndroidManifest.xml'
        java.srcDirs = ['src']
        resources.srcDirs = ['src']
        aidl.srcDirs = ['src']
        renderscript.srcDirs = ['src']
        res.srcDirs = ['res']
        assets.srcDirs = ['assets']
    }

    // Move the tests to tests/java, tests/res, etc...
    instrumentTest.setRoot('tests')

    // Move the build types to build-types/<type>
    // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
    // This moves them out of them default location under src/<type>/... which would
    // conflict with src/ being used by the main source set.
    // Adding new build types or product flavors should be accompanied
    // by a similar customization.
    debug.setRoot('build-types/debug')
    release.setRoot('build-types/release')
}
}

它给出:错误:(1, 0) 未找到 ID 为“com.android.application”的插件。

任何帮助将不胜感激......

这个错误信息意味着它根本找不到插件。在 Gradle 中，你需要告诉它去哪里寻找插件，这不同于告诉它去哪里解决模块依赖。将此 block 添加到构建文件的开头:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

在 Android Studio 创建的项目中，New Project 向导会将其放入项目的顶级构建文件中，但根据屏幕截图，您的项目似乎只有一个构建文件，因此只有一个位置把它。
