Android：已存在的程序类型：com.google.common.base.FinalizableReferencequeue

Question

在我的gradle构建过程中出现以下错误：

程序类型已存在：com.google.common.base.FinalizableReferencequeue

我知道网站上有一些类似的错误解决方案。但他们不为我工作+他们不帮我找出错误的根本原因。有人可以请一些指点吗？

应用级gradle文件：

buildscript {

    maven { url 'https://maven.fabric.io/public' }

    classpath 'io.fabric.tools:gradle:1.+'

apply plugin: 'com.android.application'

Answer 1

根本原因是2个库使用相同的依赖项。

这通常发生在嵌入另一个库（例如fat jar）的库中，但您也将其声明为依赖项（即通过单词compile）

在您的情况下，您有两个（或更多）使用com.google.common.base.FinalizableReferencequeue的库，经过短搜索后，它们对应Guava，并且是您的依赖项之一。

一个简单的解决方案是删除行compile 'com.google.guava:guava:19.0'。

但是，如果您想知道如何解决问题，可以为您的应用运行依赖项任务。这里app指的是项目下模块的名称。

// run gradlew which is on your root project.

// linux / osx
./gradlew app:dependencies

// windows
gradlew app:dependencies

这将打印所有配置及其依赖项。要缩小范围，您可以通过添加例如--configuration debugCompileClasspath或者使用名为myFlavor --configuration myFlavorDebugCompileClasspath（区分大小写）的风格来仅关注一个构建。

您现在应该能够看到哪些其他库正在使用番石榴并将其排除在外：

compile(<dependency_path>) { //works also with project(<proj_name>)
    exclude group: "com.google.guava", module: "guava" 
}
