Gradle 错误 - 任务 ':app:dexDebug' 执行失败 [英] Gradle error - Execution failed for task ':app:dexDebug'

问题描述

我正在尝试将 MPAndroidChartLibrary 添加到我的 Android Studio 项目中，但是当我尝试运行该应用程序时，它一直失败并出现 1 个错误.我对 gradle 不是很了解，所以我真的不知道出了什么问题.

I am trying to add the MPAndroidChartLibrary to my Android Studio project, however when I try to run the app, it keeps failing with 1 error. I am not very good with gradle, so I don't really know whats going wrong.

我的 gradle 文件是这样的:

My gradle file is this:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.0.2"

    defaultConfig {
        applicationId "com.bacon.corey.audiotimeshift"
        minSdkVersion 16
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

repositories {
    flatDir {
        dirs 'libs'
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:21.0.0'
    compile 'com.nineoldandroids:library:2.4.0'
    compile 'com.android.support:support-v4:21.0.0'
    compile 'com.android.support:support-v4:21.0.0'
    compile files('C:/Users/Corey/.AndroidStudioBeta/Projects/AudioTimeShift/libraries/mpandroidchartlibrary-1-7-4.jar')
}

据我所知，这应该没问题，但它不起作用.这是来自 Gradle 控制台的日志:

As far as I can see, this should all be fine, however it is not working. This is the log from the Gradle console:

如果有人能给我一些关于我哪里出错的提示，我将不胜感激.

If someone could please give me a few pointers as to where I am going wrong, I would be immensively grateful.

谢谢，科里 B :)

推荐答案

MPAndroidChart 已经将 com.nineoldandroids:library:2.4.+ 作为依赖项.从您的依赖项中删除 compile 'com.nineoldandroids:library:2.4.0'.

MPAndroidChart already has com.nineoldandroids:library:2.4.+ as a dependency. Remove compile 'com.nineoldandroids:library:2.4.0' from your dependencies.
