这些没有帮助

无法使用模块编译项目

无法解析“:app@debugUnitTest/compileClasspath”、:app@debugAndroidTest/compileClasspath 的依赖关系

应用程序分级。

apply plugin: 'com.android.application'

android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    compileSdkVersion 27
    defaultConfig {
        applicationId ".."
        minSdkVersion 18
        targetSdkVersion 27
        versionCode 13
        versionName "Beta 1.11"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        vectorDrawables.useSupportLibrary = true
        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    lintOptions {
        checkReleaseBuilds false
        // Or, if you prefer, you can continue to check for errors in release builds,
        // but continue the build even when errors are found:
        abortOnError false
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "com.android.support:design:$supportLibVer"
    implementation "com.android.support:appcompat-v7:$supportLibVer"
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

...

    implementation project(path:':libname', configuration: 'default')

}


}

库梯度

apply plugin: 'com.android.library'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "..."
        minSdkVersion 18
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

我有

include ':app', ':libname'

在设置 gradle 中

Answer 1

您有几个选择。

选项1）

通过文件菜单导入模块，让 Android 将其复制到您的根目录中并更新 Gradle 和 IDEA 文件等。

选项 2)

您可以通过相对路径导入它。并不总是推荐，但确实有效。当然，您必须认识到您的相对路径可能与其他开发人员不匹配，因此如果您决定走这条路线，存储库的文件夹结构匹配非常重要。

settings.gradle 应该包括

include 'app', ':Module 2'
project(':Module 2').projectDir = new File('../../YourPath/Project B/Module 2')

然后在您应该包含的应用程序的 build.gradle 中

implementation project(':Module 2')

公平警告，一些开发人员讨厌您这样做，但我认为在开发周期中保留最新的存储库的价值，当您发现问题时，该存储库可能仍在变化。所以在年轻的模块上有这样的情况。

选项 3)

使用 Gradle 从 Maven、jitpack 或 Ivy 存储库导入已编译的二进制文件。这假设您的模块已经成熟并且可以打包和使用。
