在Gradle项目中找不到React本机库

Question

我有反应原生项目,使用react-native@0.36.0.我正在尝试将版本升级到0.40.0.在build.gradle中有以下行:

buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.0'
    }

}

apply plugin: 'com.android.library'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    lintOptions {
        abortOnError false
    }
}

repositories {
    mavenLocal()
    jcenter()
    maven {
        // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
        url "$projectDir/../../../node_modules/react-native/android"
    }
}

dependencies {
    compile 'com.facebook.react:react-native:+'
    compile 'org.slf4j:slf4j-api:1.7.22'
}

当更新了反应原生的npm版本时,所有"import com.facebook.react"变为红色.我错过了什么？

谢谢.

更新:我看到在/ build/intermediates/explosion-aar中有版本0.36.0,尽管在app.iml中我有行:

<excludeFolder url="file://$MODULE_DIR$/build/intermediates/exploded-aar/com.facebook.react/react-native/0.40.0/jars" />

和

<orderEntry type="library" exported="" name="react-native-0.40.0" level="project" />
