我创建了一个新的项目在Android Studio 2.2预览1与Android应用程序和后端模块谷歌消息。这是app文件:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"
    defaultConfig {
        applicationId "com.xxx.xxx"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:23.4.0'
    compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha1'
    compile 'com.google.android.gms:play-services-gcm:9.0.0'
    testCompile 'junit:junit:4.12'
    androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2'
    androidTestCompile 'com.android.support.test:runner:0.5'
    androidTestCompile 'com.android.support:support-annotations:23.4.0'
    compile project(path: ':backend', configuration: 'android-endpoints')
}

但它给予:

错误:与依赖项“com.google.code.findbugs:jsr305”冲突。应用程序(1.3.9)和测试应用程序(2.0.1)的解析版本不同。详情见http://g.co/androidstudio/app-test-app-conflict。

我是Android的新手,无法找到这个错误是什么。我该怎么解决呢?


当前回答

这是由于浓缩咖啡。你可以将以下内容添加到你的应用构建中。分级来减轻这一点。

androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2') {
  exclude group: 'com.google.code.findbugs'
}

其他回答

在应用程序的构建中。Gradle添加以下内容:

android {
    configurations.all {
        resolutionStrategy.force 'com.google.code.findbugs:jsr305:1.3.9'
    }
}

强制Gradle只编译你为所有依赖项声明的版本号,不管依赖项声明的是哪个版本号。

The accepted answer is one way of fixing the issue, because it will just apply some strategy for the problematic dependency (com.google.code.findbugs:jsr305) and it will resolve the problem around the project, using some version of this dependency. Basically it will align the versions of this library inside the whole project. There is an answer from @Santhosh (and couple of other people) who suggests to exclude the same dependency for espresso, which should work by the same way, but if the project has some other dependencies who depend on the same library (com.google.code.findbugs:jsr305), again we will have the same issue. So in order to use this approach you will need to exclude the same group from all project dependencies, who depend on com.google.code.findbugs:jsr305. I personally found that Espresso Contrib and Espresso Intents also use com.google.code.findbugs:jsr305.

我希望这些想法能帮助一些人意识到这里到底发生了什么以及事情是如何工作的(而不仅仅是复制粘贴一些代码):)。

方法1: 我删除了espresso-core行上的androidTestCompile,它会自动包含在一个新项目中。然后我的Android Studio编译干净。

androidTestCompile在build中。gradle(模块:应用)”:

dependencies {
    ...
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    ...
}

我不知道这种删除是否会有任何问题,但它肯定适用于我目前的项目。

方法2:在findbugs上添加一个排除也可以:

dependencies {
    ...
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
        exclude group: 'com.google.code.findbugs'
    })
    ...
}

方法3:使用特定版本强制编译: (在下面的代码中,我强制它使用更高版本编译。)

dependencies {
    ...
    androidTestCompile 'com.google.code.findbugs:jsr305:3.0.0'
    ...
}

删除浓缩咖啡依赖在gradle文件为我工作。

删除应用程序gradle文件中的这些行:

androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'
})
