Android 如何使gradle命令行生成从干净的生成安装multidex？

我在尝试从一个干净的版本（用于Jenkins CI）构建Android项目的命令行时遇到了问题。如果我在Android Studio中打开项目并运行带有Gradle文件的

Tools>Android>Sync项目

，我随后可以从命令行进行构建。但是，如果我尝试从命令行运行

/gradlew build

，而没有首先在Android Studio中打开项目，我会收到以下生成失败：

FAILURE: Build failed with an exception.

BUILD FAILED

据我所知，我拥有Gradle脚本中指定的所有适当依赖项：

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        mavenCentral()
        maven { url 'http://download.crashlytics.com/maven' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.0'
        classpath 'com.crashlytics.tools.gradle:crashlytics-gradle:1.+'
    }
}

和我的应用程序级Gradle脚本：

...
dependencies {
    ...
    compile 'com.android.support:multidex:1.0.0'
    ...
}

android {
...

另外，.gitignore的某些内容：

# Android Studio and Gradle
build/
local.properties
.gradle
gradle-app.setting
*.iml
.idea/
*.ipr
*.iws
out/
.idea_modules/

为什么不能从干净的命令行版本中找到multidex？我如何解决这个问题？

Android Studio和我的命令行版本使用不同的Android SDK安装。我在命令行上使用的那一个没有安装一些必需的附加软件包。一旦我安装了它们，构建工作正常
