无法在 Gradle 依赖项中添加 Android 材料设计库，我收到此错误

Question

每次我在 Gradle 依赖项中添加 Android 材料设计库时，我都会收到此错误 错误：任务 ':app:dexDebug' 执行失败。

com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command'/Library/Java/JavaVirtualMachines/jdk1.8.0_20.jdk/Contents/Home/bin/java '' 以非零退出值 2 结束

当我添加 Multidex 支持时，我得到了

非零退出值 3

这是我的 gradle 文件

apply plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion "23.0.1"

defaultConfig {
    applicationId "com.myex.exam"
    minSdkVersion 9
    targetSdkVersion 21
    versionCode 1
    versionName "1.0"


}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
sourceSets { main { assets.srcDirs = ['src/main/assets', 'src/main/assets/'] } }

}

dependencies {
provided fileTree(dir: 'libs', include: ['*.jar'])
compile'com.android.support:appcompat-v7:23.0.1'
compile 'com.google.android.gms:play-services:7.8.0'
compile 'com.android.support:recyclerview-v7:21+'
compile 'com.android.support:design:23.0.1'
compile files('src/main/libs/jackson-all-1.9.11.jar')
compile files('src/main/libs/picasso-2.5.2.jar')

}
