无法构建：如何为新模块添加 Android 构建配置

Question

现在我正在将我的 android 代码转换为模块化架构方法。尝试从 "chat" 模块添加对 "app" 模块的依赖时遇到问题。

我有以下 "app" 模块的构建配置。

android {

lintOptions {
    checkReleaseBuilds false
    abortOnError false
}

signingConfigs {
    companydevconfig {
        keyAlias 'company'
        keyPassword '123456'
        storeFile file('../app/jksFils/company_dev.jks')
        storePassword '123456'
    }
    companyqaconfig {
        keyAlias 'company'
        keyPassword '123456'
        storeFile file('../app/jksFils/company_qa.jks')
        storePassword '123456'
    }
    companyprodconfig {
        keyAlias 'company'
        keyPassword '123456'
        storeFile file('../app/jksFils/release.keystore')
        storePassword '123456'
    }
}

compileSdkVersion 28
buildToolsVersion '28.0.3'
defaultConfig {
    applicationId "com.company.employee.dev"
    minSdkVersion 21
    targetSdkVersion 28
    versionCode 1
    versionName "1.13"
    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    multiDexEnabled true
}
aaptOptions {
    cruncherEnabled = false
}
testOptions {
    unitTests.returnDefaultValues = true
}
buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
    debug {
        testCoverageEnabled true
    }

}

sourceSets {
    main.java.srcDirs += 'src/main/kotlin'
}

dataBinding {
    enabled = true
}
packagingOptions {
    exclude 'META-INF/ASL2.0'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/rxjava.properties'
}
flavorDimensions "company"
productFlavors {
    dev {
        dimension "company"
        applicationId "com.company.employee.dev"
        versionCode 277
        versionName "2.0.0.16"
        signingConfig signingConfigs.companydevconfig

        buildConfigField 'String', 'BASEURL', '"https://dev.company.com"'
    }
    qa {
        dimension "company"
        applicationId "com.company.employee.qa"
        versionCode 225
        versionName "2.0.2.2"
        signingConfig signingConfigs.companyqaconfig

        buildConfigField 'String', 'BASEURL', '"https://qa.company.com"'

    }
    prod {
        dimension "company"
        applicationId "com.company.employee.prod"
        versionCode 38
        versionName "1.5.20"
        signingConfig signingConfigs.companyprodconfig

        buildConfigField 'String', 'BASEURL', '"https://cloud.company.com"'

    }
}
compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}
testOptions {
    unitTests.returnDefaultValues = true
    unitTests.all {
        setIgnoreFailures(true)
        jacoco {
            includeNoLocationClasses = true
        }
    }
  }
}

现在我添加了一个新模块"chat"。它在构建配置中有以下代码。

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'

android {
compileSdkVersion 29
buildToolsVersion "29.0.2"

defaultConfig {
    applicationId "com.company.employee.chat"
    minSdkVersion 21
    targetSdkVersion 29
    versionCode 1
    versionName "1.0"

    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
    debug {
    }
}
sourceSets {
    main.java.srcDirs += 'src/main/kotlin'
}

dataBinding {
    enabled true
}

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

kotlinOptions {
    jvmTarget = "1.8"
}
}

dependencies {
implementation project(':app')

implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
}

当我尝试构建时出现以下错误。

resolve project :app.

Answer 1

这里有一些需要考虑的事情

App Module和Library Module有区别。

库模块符合.aar/file。但是，App 模块 被编译为 APK。这意味着您不能将 App Module 作为 Library Module 的依赖导入。因此，从库模块中删除此行：

 implementation project(':app')

确保图书馆列在 settings.gradle 的顶部。

打开应用程序模块的 settings.gradle 并确保列出了您的图书馆

include ':app', ':chat'

将库模块导入到您的应用程序模块构建Gradle

将您的库模块导入为依赖项

dependencies {
implementation project(':chat')
}

最重要的是看看:Create an Android library

Answer 2

您可能正在导入 Application 而不是 Module。那么，您也可以在模块的 Gradle 中更改它。

Change

apply plugin: 'com.android.application'

to

apply plugin: 'com.android.library'

您还需要从 gradle.

中删除 applicationId

然后，在 app.gradle 的 依赖项中，

而不是

implementation project(':lib-name')

我用过，

implementation project(path:':lib-name', configuration: 'default')

Eg: implementation project(path:':myService', configuration:
'default')

而且效果非常好。 :)

我正在添加一个带有服务的依赖模块，而不是将库作为 AOSP 项目的一部分。

以防万一，它可以帮助某人。
