在实现Google +登录时在build.gradle中重复输入

Question

我试图在this教程中将Google+注册/登录集成到Android Studio中导入的旧版（Eclipse）项目中。在导入build.gradle文件时，我被卡住了。

错误说：

Error:Execution failed for task ':Study Story:transformClassesWithJarMergingForDebug'. 
> com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: android/support/v4/print/PrintHelperKitkat$1.class 

我不能到调试的这种错误的原因。内水平的build.gradle文件有以下代码：

import java.util.regex.Pattern 

apply plugin: 'android' 

apply plugin: 'com.github.triplet.play' 
apply from: 'signingRelease.gradle' 
apply plugin: 'signing'

     targetSdkVersion 21 

     // Enabling multidex support. 
     multiDexEnabled true 

     // For blurring images

    System.properties['com.android.build.gradle.overrideVersionCheck'] = 'true' 

} 

allprojects { 
    repositories { 
     jcenter()

的文件夹结构看起来像下面图像：

请指出我需要修改以解决问题的区域。

Answer 1

首先，尽量使用相同的API为compileSdkVersion，buildToolsVersion，targetSdkVersion，support:appcompat依赖，support:design依赖，support-recyclerview依赖，依赖support:cardview。在您的应用程序build.gradle中，您需要坚持到API 23。

据我所知，如果你使用：（如果我的记忆为我好）

compile 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2' 

，因为它做同样与useLibrary：

useLibrary 'org.apache.http.legacy' 

你不需要添加这种依赖关系。

然后在你的根的build.gradle，你只需要一个构建工具的gradle：

//classpath 'com.android.tools.build:gradle:1.3.0' Use only one. 
classpath 'com.android.tools.build:gradle:2.1.0' 

而在去年，尽量不要使用multidex为您的应用程序。因为没有multidex，Android应用程序更快。 Imho，通过浏览你的build.gradle，你可以不用multidex。

Answer 2

首先确保您的Android SDK已更新，并使用您指定为您的项目依赖项的相同版本的库。现在回答这个错误：

这些导入：所以你需要如下排除它们

Error:Execution failed for task ':Study Story:transformClassesWithJarMergingForDebug'. 
> com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: android/support/v4/print/PrintHelperKitkat$1.class 

com.android.support:support-v4和支持的注解包导入不同版本多次support-v4，support-annotations 23.0.0：

compile('com.google.android.gms:play-services-auth:9.0.0') { 
     exclude module: 'support-v4' 
     exclude module: 'support-annotations' 
    } 

compile('com.google.android.gms:play-services-maps:9.0.0') { 
      exclude module: 'support-v4'  
      exclude module: 'support-annotations' 
     } 

compile('com.google.android.gms:play-services-analytics:9.0.0') { 
       exclude module: 'support-v4' 
       exclude module: 'support-annotations'   
      } 

这是导入support-v4，support-annotations 22.0.0。

// Just don't import this library as it's already imported in 'com.android.support:design' 
    compile('com.android.support:appcompat-v7:22.2.0') { 
         exclude module: 'support-v4' 
         exclude module: 'support-annotations' 
        } 

这是导入support-v4 25.0.1。你永远不应该指定具有依赖关系的依赖项：'com.android.support:design:22.+'，因为它总是会强制项目使用最新的库，同时构建可能导致几个构建错误的gradle，一些不推荐使用的类你的项目不稳定。总是建议及时更新SDK并相应地指定相关版本，并验证写入的代码是否是您的项目不会丢失最新库中的任何类。实际上，设计库正在导入support-v4，appcompat-v7，support-annotations，recyclerview-v7，因此您应该避免单独导入这些库。

compile 'com.android.support:design:25.0.1' 

它再次导入support-v4，support-annotations 22.2.1。

// Just don't import this library as it's already imported in 'com.android.support:design' 
    compile('com.android.support:recyclerview-v7:22.2.1') { 
           exclude module: 'support-v4' 
           exclude module: 'support-annotations'   
          } 

这个库下面导入模块具有23.1.1版本：

compile('com.github.orangegangsters:swipy:1.2.3@aar') { 
            exclude module: 'support-v4' 
            exclude module: 'appcompat-v7' 
            exclude module: 'support-annotations'   
           } 

它导入支持的注解：22.0.0

compile('com.github.traex.rippleeffect:library:1.3') { 
             exclude module: 'support-annotations'   
            }
