请帮忙！ 我已经试图解决这个问题2天，并尝试了几乎所有我能找到的东西，但没有运气。 该应用程序构建正常，但是当我生成项目时，我收到此错误。 在Windows 10 64位上运行Android Studio 2.3，jdk 1.8 已经尝试过使用Jack和番石榴版20.0 这是我的gradle.build：
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.0'

// in the individual module build.gradle files

答案 0 :(得分：0)
感谢Rahul，我想出了如何解决这个问题。正如他提到的那样，问题是我包含了不同版本的番石榴。所以首先我在Android Studio终端中运行它：
gradlew -q dependencies app:dependencies --configuration compile
其中“app”是您的项目。这向我展示了所有依赖项的列表，并看到了包含的不同版本的番石榴。 然后我从包含的项目中排除了每个重复版本的番石榴，如下所示：
testCompile ('org.robolectric:robolectric:3.1') {
exclude module: 'guava'
}
希望这有助于某人：）
