编译 React-native 重复条目时出错：javax/inject/Inject.class

Question

我从网上下载了一个名为 react-native-obd2 的 React-native 项目。在我开始之前，我只想运行回购协议中已经给出的例子，但是当运行宁 react-native run-android 我陷入了一个错误。

:app:transformClassesWithJarMergingForDebug FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:transformClassesWithJarMergingForDebug'.
> com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: javax/inject/Inject.class

为了解决这个问题，我已经绞尽脑汁 3 个多小时了，但还是不行。

我尝试了各种解决方案，对我来说最合乎逻辑的解决方案之一是 javax/inject/Inject.class 在某个地方被调用了两次。

所以我输入了这个命令来获取 gradle 类路径。
./gradlew -q dependencies app:dependencies --configuration compile

但我没有看到 javax 被写了两次。还提到检查下载项目和文件的版本，但我找不到任何显着差异。

这里是 build.gradle

apply plugin: "com.android.application"

import com.android.build.OutputFile
apply from: "../../node_modules/react-native/react.gradle"

def enableSeparateBuildPerCPUArchitecture = false

/**
 * Run Proguard to shrink the Java bytecode in release builds.
 */
def enableProguardInReleaseBuilds = false

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "com.obd2example"
        minSdkVersion 16
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
        multiDexEnabled true
        ndk {
            abiFilters "armeabi-v7a", "x86"
        }
    }
    splits {
        abi {
            reset()
            enable enableSeparateBuildPerCPUArchitecture
            universalApk false  // If true, also generate a universal APK
            include "armeabi-v7a", "x86"
        }
    }
    buildTypes {
        release {
            minifyEnabled enableProguardInReleaseBuilds
            proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
        }
    }
    // applicationVariants are e.g. debug, release
    applicationVariants.all { variant ->
        variant.outputs.each { output ->
            // For each separate APK per architecture, set a unique version code as described here:
            // http://tools.android.com/tech-docs/new-build-system/user-guide/apk-splits
            def versionCodes = ["armeabi-v7a":1, "x86":2]
            def abi = output.getFilter(OutputFile.ABI)
            if (abi != null) {  // null for the universal-debug, universal-release variants
                output.versionCodeOverride =
                        versionCodes.get(abi) * 1048576 + defaultConfig.versionCode
            }
        }
    }
}

repositories {
    maven { url "https://jitpack.io" }
}

dependencies {
    compile project(':react-native-obd2')
    compile project(':react-native-vector-icons')
    compile project(':react-native-sp')
    compile project(':react-native-sensor-manager')
    compile project(':react-native-dialogs')
    compile fileTree(dir: "libs", include: ["*.jar"])
    compile "com.android.support:appcompat-v7:23.0.1"
    compile "com.facebook.react:react-native:+"  // From node_modules
}

// Run this once to be able to run the application with BUCK
// puts all compile dependencies into folder libs for BUCK to use
task copyDownloadableDepsToLibs(type: Copy) {
    from configurations.compile
    into 'libs'
}

谁能指导我去哪里看？

为了找出 javax.inject 模块在哪里被使用了两次，我在 node_modules 文件夹中执行了 grep -r "javax.inject" 并找到了这个

react-native/android/com/facebook/react/react-native/0.34.1/react-native-0.34.1.pom:      <groupId>javax.inject</groupId>
react-native/android/com/facebook/react/react-native/0.34.1/react-native-0.34.1.pom:      <artifactId>javax.inject</artifactId>
react-native/ReactAndroid/src/main/third-party/java/jsr-330/BUCK:    url = 'mvn:javax.inject:javax.inject:jar:1',
react-native/ReactAndroid/src/main/java/com/facebook/react/CoreModulesPackage.java:import javax.inject.Provider;
react-native/ReactAndroid/src/main/java/com/facebook/react/bridge/ModuleSpec.java:import javax.inject.Provider;
react-native/ReactAndroid/src/main/java/com/facebook/react/shell/MainReactPackage.java:import javax.inject.Provider;
react-native/ReactAndroid/build.gradle:    compile 'javax.inject:javax.inject:1'

这里有什么问题吗？我不是很精通 Java 和 gradle 构建系统来理解它。

在您的 build.gradle 文件中，您可以尝试更改以下行：

compile "com.facebook.react:react-native:+" // From node_modules

为此：

compile("com.facebook.react:react-native:+") {
  exclude module: 'javax.inject'
}

该错误基本上意味着 @Inject 注释多次包含在您的最终 APK 中，并且它来自不同的地方。很难准确指出位置，但这种来自 react-native 的传递依赖很可能是来源之一。排除它有望在您的最终 apk 中只留下一个 "copy"。
