android - Android Studio无法解决:multidex打开文件

Question

无法解决:multidex
打开文件

同步项目时发现此错误。

apply plugin: 'com.android.library'

android {
    compileSdkVersion rootProject.compileSdkVersion
    buildToolsVersion rootProject.buildToolsVersion

    defaultConfig {
        minSdkVersion 16
        targetSdkVersion rootProject.targetSdkVersion
        versionCode 1
        versionName "1.0"
        multiDexEnabled true
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

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

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    def system_dependencies = rootProject.ext.system_dependencies
    compile system_dependencies.appcompat_v7
    testCompile 'junit:junit:4.12'
}

我添加了它，但是它不起作用。

maven {
    url 'https://maven.google.com'
}

我尝试了很多方法。如何解决？

在项目build.gradle中

    allprojects {
    repositories {
        /**
         * This must be at the top.
         */
        maven {
            url 'https://maven.google.com'
        }
        // Others 
        maven { url "..." }
        jcenter()
        mavenCentral()
        google()
    }
   }
