Question

我尝试将一个正在运行的Eclipse Android项目导入Android Studio。我正在Mac上使用最新版本的Android Studio。当我尝试构建时，它会继续显示此错误：

错误：任务执行失败   '：应用程序：transformClassesWithJarMergingForDebug'。


com.android.build.api.transform.TransformException：java.util.zip.ZipException：重复条目：     COM /谷歌/ API /客户端/ HTTP / AbstractHttpContent.class

产生此问题的类位于com.google.http-client：google-http-client-gson：1.20.0库中，位于com.google.api.client.http包中。我在app.gradle文件中尝试了很多东西，例如排除了com.google.api.client.http组，但没有任何效果。这是我的app.gradle文件：

apply plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
useLibrary  'org.apache.http.legacy'

defaultConfig {
    applicationId "com.example.time2"
    minSdkVersion 17
    targetSdkVersion 19
    multiDexEnabled true
}

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
    }
}
compileOptions.encoding = 'ISO-8859-1'
}

repositories {
mavenCentral()
}

dependencies {
compile 'com.android.support:support-v4:20.0.0'
compile 'com.google.android.gms:play-services:+'
compile 'com.google.http-client:google-http-client-gson:1.20.0'
compile 'com.google.code.gson:gson:2.1'
compile files('libs/commons-io-2.4.jar')
compile files('libs/google-api-client-1.18.0-rc.jar')
compile files('libs/google-api-client-android-1.18.0-rc.jar')
compile files('libs/google-http-client-1.18.0-rc.jar')
compile files('libs/google-http-client-android-1.18.0-rc.jar')
compile files('libs/google-oauth-client-1.18.0-rc.jar')
compile files('libs/httpcore-4.3.3.jar')
compile files('libs/httpmime-4.3.6.jar')
compile files('libs/json-simple-1.1.1.jar')
compile files('libs/jsr305-1.3.9.jar')
compile 'com.stripe:stripe-android:+'
compile 'com.facebook.android:facebook-android-sdk:4.7.0'
}

您应该避免手动将libs添加到项目中。

E.g. change
compile files('libs/commons-io-2.4.jar')
compile files('libs/google-api-client-1.18.0-rc.jar')
compile files('libs/google-api-client-android-1.18.0-rc.jar')
compile files('libs/google-http-client-1.18.0-rc.jar')
compile files('libs/google-http-client-android-1.18.0-rc.jar')
compile files('libs/google-oauth-client-1.18.0-rc.jar')
compile files('libs/httpcore-4.3.3.jar')
compile files('libs/httpmime-4.3.6.jar')
compile files('libs/json-simple-1.1.1.jar')
compile files('libs/jsr305-1.3.9.jar')

to

compile 'commons-io:commons-io:2.4'
compile 'com.google.api-client:google-api-client:1.18.0-rc'
compile 'com.google.api-client:google-api-client-android:1.18.0-rc'
compile 'com.google.http-client:google-http-client:1.18.0-rc'
compile 'com.google.http-client:google-http-client-android:1.18.0-rc'
compile 'com.google.oauth-client:google-oauth-client:1.18.0-rc'
compile 'org.apache.httpcomponents:httpcore:4.3.3'
compile 'org.apache.httpcomponents:httpmime:4.3.6'
compile 'com.googlecode.json-simple:json-simple:1.1.1'
compile 'com.google.code.findbugs:jsr305:1.3.9'

请确认这些是正确的包裹。让我们知道您在更新后发现了什么？

库'com.google.http-client:google-http-client-gson:1.20.0'由以下九个模块组成：

google-http-client
google-http-client-android
google-http-client-appengine
google-http-client-xml
google-http-client-protobuf
google-http-client-jdo
google-http-client-jackson
google-http-client-jackson2
google-http-client-gson

其中一些例如google-http-client作为jar再次包含在巡视依赖项中。因此重复的条目。

使用google-http-java-client时，请检查此链接以获得正确的设置。它有一步一步的指示 - Setup Instructions
