问题描述

我已将 Android Studio 更新到版本 3，现在似乎无法编译我之前编译的项目而没有错误.

I have updated Android Studio to version 3 and now seems unable to compile my project previously compiled without errors.

错误信息如下

Error:Error: commons-logging 定义的类与现在由 Android 提供的类.解决方案包括寻找更新的没有相同问题的版本或替代库(例如，对于 httpclient 使用 HttpUrlConnection 或 okhttp 代替)，或使用 jarjar 之类的东西重新打包库.[重复平台类]

Error:Error: commons-logging defines classes that conflict with classes now provided by Android. Solutions include finding newer versions or alternative libraries that don't have the same problem (for example, for httpclient use HttpUrlConnection or okhttp instead), or repackaging the library using something like jarjar. [DuplicatePlatformClasses]

依赖关系是

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:27.0.0'
    compile 'com.android.support:design:27.0.0'
    compile 'com.google.api-client:google-api-client-android:1.23.0' exclude module: 'httpclient'
    compile 'com.google.http-client:google-http-client-gson:1.23.0' exclude module: 'httpclient'
    compile 'com.google.firebase:firebase-core:11.4.2'
}

错误似乎是由

compile 'com.google.api-client:google-api-client-android:1.23.0' exclude module: 'httpclient'
compile 'com.google.http-client:google-http-client-gson:1.23.0' exclude module: 'httpclient'

我已经在使用 exclude module: 'httpclient'那么为什么它不编译?这是 Android Studio 3 的错误和或包含 com.android.tools.build:gradle:3.0.0 插件还是我遗漏了什么?与以前的版本编译完全一样的项目没问题.

I already use exclude module: 'httpclient' So why It doesn't compile? Is this a bug of Android Studio 3 andor included com.android.tools.build:gradle:3.0.0 plugin or I'm missing something? With the previous version no problem to compile exactly the same project.

推荐答案

添加到应用模块中的 build.gradle

Add to build.gradle located in app module

configurations {
    all {
        exclude module: 'httpclient'
    }
}
