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?
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):)。
从Gradle插件用户指南:
When instrumentation tests are run, both the main APK and test APK share the same classpath. Gradle build will fail if the main APK and the test APK use the same library (e.g. Guava) but in different versions. If gradle didn't catch that, your app could behave differently during tests and during normal run (including crashing in one of the cases).
To make the build succeed, just make sure both APKs use the same version. If the error is about an indirect dependency (a library you didn't mention in your build.gradle), just add a dependency for the newer version to the configuration
将这一行添加到构建中。gradle依赖使用更新版本的apk:
收集(“com.google.code.findbugs: jsr305:2.0.1')
为了将来的参考，你可以检查你的Gradle控制台，它会在错误旁边提供一个有用的链接来帮助解决任何Gradle构建错误。
