将Android Studio升级到2.1.2，现在出现构建错误

Question

我的项目之前构建得很好，但现在升级到Android Studio 2.1.2时出现错误：

以下是我在build.gradle文件中的内容：

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

    dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
    }
}
apply plugin: 'android'
apply plugin: 'io.fabric'

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


android {
    compileSdkVersion 19
    buildToolsVersion '19.1.0'

    defaultConfig {
        applicationId "com.puc.mobile"
        minSdkVersion 14
        targetSdkVersion 19
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    //compile files('libs/crashlytics.jar')
    compile files('libs/FLurry_3.2.2.jar')
    compile files('libs/universal-image-loader-1.9.2.jar')
    // You must install or update the Support Repository through the SDK manager to use this dependency.
    // You must install or update the Google Repository through the SDK manager to use this dependency.
    compile files('libs/commons-lang3-3.4.jar')
    compile('com.crashlytics.sdk.android:crashlytics:2.5.7@aar') {
        transitive = true;
    }
    compile fileTree(dir: 'libs', include: 'Parse-*.jar')
    compile files('libs/Parse-1.13.0.jar')
    compile 'com.android.support:support-v4:19.0.0'
    compile 'com.google.android.gms:play-services:9.2.0'
    compile 'com.parse.bolts:bolts-android:1.+'
    compile 'com.google.android.gms:play-services-ads:9.2.0'
    compile 'com.google.android.gms:play-services-auth:9.2.0'
    compile 'com.google.android.gms:play-services-gcm:9.2.0'
}

我意识到构建工具版本存在一些问题，但说实话，我不确定如何修复它。有线索吗？

更新

如下所述更新buildToolsVersion后，我收到错误：

Answer 1

这是因为Build Tools修订版19.1.0不存在。

最新版本为23.0.3.

这些工具包含在SDK包中，并安装在<sdk>/build-tools/目录中。

更改build.gradle

android {
   buildToolsVersion "23.0.3"
   // ...

}
