java - Gradle 项目 - 可以构建但不能运行它

Question

我的 Android 项目由 3 个 build.gradle 文件组成:

项目build.gradle:

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
//        mavenLocal()
        jcenter()
    }
    dependencies {
//        classpath 'com.android.tools.build:gradle:1.1.0'
        classpath 'com.android.tools.build:gradle:1.1.3'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

MYAPP build.gradle

apply plugin: 'com.android.library'
android {
    dexOptions {
        preDexLibraries = false
    }

    compileSdkVersion 17
    buildToolsVersion "21.1.1"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 17
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile 'com.android.support:support-v4:18.0.0'
    compile files('libs/CWAC-AdapterWrapper.jar')
}

和 Facebook SDK:

apply plugin: 'com.android.library'

android {
    dexOptions {
        preDexLibraries = false
    }
    compileSdkVersion 8
    buildToolsVersion "21.1.1"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 8
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    } }

dependencies {
    compile 'com.android.support:support-v4:18.0.0' 
}

我能够构建该项目，但无法运行它。异常(exception)是:

有些东西是重复的，但我不知道是什么。您有任何想法为什么它不运行吗？

问题似乎是前 2 个模块在我的 DEX 中包含了两次

settings.gradle include ':androidImageCachemaster' include ':facebookSDK'

然后

¸¸dependencies { compile project(':facebookSDK') compile project(':androidImageCachemaster')

这是屏幕截图

Answer 1

文件中是否有一个名为DiskCache的函数: com.android.dx.command.Main.main

这似乎与 facebook sdk 中的功能冲突。尝试重命名您的函数

已更新------

在你的 build.grade 中试试这个。这应该编译依赖项，但将其从最终构建中排除:

android {
    compileSdkVersion x
    buildToolsVersion "x"

    packagingOptions {
        exclude 'support-v4'
    }
    ...
}
