意外的顶级异常：android studio 和 andengine 重复类

Question

我正在使用 Android Studio 和 AndEngine 库和 TexturePacker 扩展，使用此链接进行设置：

Setting Up AndEngine with Android Studio

我遇到了这个问题：

Error:Class org.andengine.BuildConfig has already been added to output. Please remove duplicate copies.

1 error; aborting

Error:Execution failed for task ':app:dexDebug'.

> com.android.ide.common.internal.LoggedErrorException: Failed to run command:

Error Code:

Output:

我什么都试过了。清理项目，删除 BuildConfig 类（它们是在 texturepacker 库中自动创建的），排除模块，重新导入第三方库......但似乎没有什么可以修复它。

这里是我的 build.gradle 文件：

应用：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.zmaxstudios.next"
        minSdkVersion 14
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    dexOptions {
        preDexLibraries = false
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:21.0.3'
    compile 'com.android.support:support-v13:21.0.3'
    compile project(':third_party:andengine')
    compile project(':third_party:texturepacker')
}

AndEngine > build.gradle

apply plugin: 'android-library'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 21
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-project.txt')
        }
    }

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }

        instrumentTest.setRoot('tests')
    }
}

Texturepacker > build.gradle

apply plugin: 'android-library'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 21
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-project.txt')
        }
    }

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }

        instrumentTest.setRoot('tests')
    }
}

dependencies {
    compile project(':third_party:andengine')
}

如何删除重复的 BuildConfig 文件？或者我应该怎么做才能解决这个问题？ 谢谢

Answer 1

您的问题似乎在于您的依赖关系，在我的情况下是这样的。

compile 'com.google.android.gms:play-services:6.5.87'// and here's the issue

Google Play 服务库可能非常大，当与许多第三方库或一些较新的 Google 库结合使用时，这可能会成为您体验的冗余。我在实施 Google Cloud Storage 时遇到了类似的问题。通常，我现在只包含我真正需要的 android 支持库，即

compile 'com.google.apis:google-api-services-storage:v1-rev18-1.19.0'
compile 'com.google.http-client:google-http-client-jackson2:1.20.0'
compile 'com.google.oauth-client:google-oauth-client-jetty:1.20.0'
compile 'com.google.api-client:google-api-client-java6:1.20.0'
compile 'com.google.android.gms:play-services-maps:7.3.0'
compile 'com.google.android.gms:play-services-location:7.3.0'

Answer 2

能否请您从依赖项中删除这一行？我在这里看到您正在使用两个支持库。清理并构建您的项目

compile 'com.android.support:support-v13:21.0.3'

Answer 3

我终于解决了这个问题，它与支持库无关。我从第三方库中得到了问题，因为 texturepacker 库的清单文件按照问题中提供的链接中的步骤具有相同的 andengine 包，因此 BuildConfig.java 类被复制。现在，清单文件是：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="org.andengine" >

    <application>

    </application>

</manifest>

和纹理打包器：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="org.andengine.extension.texturepacker.opengl.texture.util.texturepacker" >

<application>

</application>

</manifest>

希望对您有所帮助。

谢谢大家的回答。
