使用不带发布版本的android测试插件时，避免出现“变量选择冲突"警告 [英] Avoid 'Variant Selection Conflicts' warning when using android test plugin without release variant

问题描述

我想做什么&问题

我将Android Studio和Android Gradle插件更新为3.0.1，并将Gradle Wrapper更新为4.1，并且可以构建&通过IDE将我的Android Gradle项目以发行版本部署在设备上.

I updated my Android Studio and Android Gradle Plugin to 3.0.1 and my Gradle Wrapper to 4.1 and can build & deploy my Android Gradle project in release variant on a device via IDE.

• 但是，会显示以下"Gradle Sync"警告消息:

• However, the following 'Gradle Sync' warning messages are shown:

警告:模块库"已选择变体发布"，但是模块['integration-test']依赖于变体调试"

Warning:Module 'library' has variant 'release' selected, but the modules ['integration-test'] depend on variant 'debug'

这里的问题是，使用'com.android.test'的 integration-test 模块没有'release'变体插件.

The problem here is, that there is no 'release' variant for the integration-test module which uses the 'com.android.test' plugin.

如果我只是尝试将发布构建类型( buildTypes {release {}} )添加到:integration-test模块，我将收到:

If I simply try to add a release build type (buildTypes { release {} }) to the :integration-test module I receive:

错误:VariantInputs初始化时没有关于DEFAULT的合并清单报告

Error:VariantInputs initialized with no merged manifest report on: DEFAULT

有关该项目的详细信息(简化)

该项目包括:

• 一个:图书馆模块
• 一个:app模块，该模块可构建应用的apk并使用:library模块
• :集成测试模块，其中:
  • 使用"com.android.test"插件
  • 通过targetProjectPath':app'&依赖于:app模块targetVariant调试"
  • 并包含对:app函数的检测化的测试
  • 仅包含一个主"文件夹(测试插件不支持其他文件夹)
  • a :library module
  • an :app module which builds the app's apk and uses the :library module
  • an :integration-test module which:
    • uses the "com.android.test" plugin
    • dependents on the :app module via targetProjectPath ':app' & targetVariant 'debug'
    • and contains instrumented tests on the :app functions
    • only contains a 'main' folder (the test plugin does not support others)

    settings.gradle

    settings.gradle

    include :library
    include :app
    include :integration-test
    

    app/build.gradle

    app/build.gradle

    apply plugin: 'com.android.application'
    
    android {
    compileSdkVersion rootProject.ext.compileSdkVersion
    buildToolsVersion rootProject.ext.buildToolsVersion
    
    publishNonDefault true
    
    defaultConfig {
        minSdkVersion rootProject.ext.minSdkVersion
        targetSdkVersion rootProject.ext.targetSdkVersion
    
        applicationId "xxxxx"
    
        testInstrumentationRunner rootProject.ext.testInstrumentationRunner
    
        multiDexEnabled true
        vectorDrawables.useSupportLibrary = true
    }
    
    signingConfigs {
        release {
            keyAlias 'xxxx'
        }
    }
    
    buildTypes {
        debug {
            testCoverageEnabled = true
        }
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.release
        }
    }
    
    // This is needed by the integration-test module (i.e. com.android.test : integration test)
    // in order for targetVariant to work without a flavor
    publishNonDefault true
    
    testOptions {
        unitTests {
            // Required so that logging methods do not throw not mocked exceptions in junit tests.
            returnDefaultValues = true
        }
    }
    
    compileOptions {
        sourceCompatibility rootProject.ext.sourceCompatibility
        targetCompatibility rootProject.ext.targetCompatibility
    }
    }
    
    dependencies {
    // Local dependencies
    compile project(':library')
    // i cleaned up all the other dependencies as they wouldn't help here
    }
    

    问题

    是否有人使用com.android.test插件获得了(集成-)测试模块，并与 Android Gradle Plugin 3.0.1 一起运行，却没有得到没有发布"的信息变体"错误?如果是这样，该如何避免该错误，或​​者如何在基于android测试插件的模块中添加这样的发行版本(如果完全有道理的话)?

    Did anyone get an (integration-)test module using the com.android.test plugin to run with Android Gradle Plugin 3.0.1 without getting the "no release variant" error? If so, how can I avoid this error or how can I add such a release variant to a android test plugin based module (if this makes sense at all)?

    推荐答案

    我也得到了

    VariantInputs初始化时没有关于DEFAULT的合并清单报告.

    VariantInputs initialized with no merged manifest report on: DEFAULT.

    然后，我完全按照 https://中概述的内容进行操作github.com/googlesamples/android-testing-templates/tree/master/AndroidTestingBlueprint

    当我从测试模块的Gradle文件中的"buildTypes"块中删除了 release buildType时，错误消失了.从这个:

    The error went away when I removed release buildType from the `buildTypes' block in the test module's Gradle file. From this:

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    

    到

    buildTypes {
    }
