Gradle 无法解析来自另一个模块的引用

Question

我有一个包含以下模块的项目:

• 应用程序
• 设备

应用程序取决于设备。设备包含应用程序引用的 NetworkComponent 类。更具体地说:

package com.some.package.ui.login;

import android.content.Intent
import android.os.Bundle
import android.support.v7.app.AppCompatActivity
import com.some.package.R
import com.some.package.device.network.NetworkComponent
import com.some.package.ui.terms.TermsActivity

class LoginActivity : AppCompatActivity(),
        LoginViewModel.Navigator {

    val loginViewModel by lazy { LoginViewModel(this, NetworkComponent()) }

Android Studio 中一切正常。然而，当我尝试构建项目时，遇到构建错误:

e: /Users/android/some-app-android/app/src/main/kotlin/com/some/package/ui/login/LoginActivity.kt: (7, 27): Unresolved reference: network
e: /Users/android/some-app-android/app/src/main/kotlin/com/some/package/ui/login/LoginActivity.kt: (13, 55): Unresolved reference: NetworkComponent

[KOTLIN] deleting /Users/android/some-app-android/app/build/tmp/kotlin-classes/debug on error
:app:compileDebugKotlin FAILED

这就是 NetworkComponent 的样子:

package com.some.package.device.network

import com.some.package.domain.datasources.CodeValidator
import retrofit2.Retrofit


class NetworkComponent : CodeValidator {

    val codeValidator: CodeValidatorApi

    init {
        val retrofit = Retrofit.Builder()
                .baseUrl("www.test.com")
                .build()

        codeValidator = retrofit.create(CodeValidatorApi::class.java)
    }

    override fun validate(code: String) = codeValidator.validate(code)
}

以下是构建文件:

顶部:

buildscript {
    ext.kotlin_version = '1.1.51'
    ext.android_tools = '3.0.0'
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath "com.android.tools.build:gradle:$android_tools"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        mavenCentral()
    }
}

应用程序:

buildscript {
    repositories {
        mavenCentral()
    }
}

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

        minSdkVersion 21
        targetSdkVersion 27
        versionCode versionMajor * 10000 + versionMinor * 100 + versionPatch
        versionName "${versionMajor}.${versionMinor}.${versionPatch}"

    }

    buildTypes {

            resValue "string", "application_name", "TEST APP Debug"
            debuggable true
        }
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            resValue "string", "application_name", "TEST APP"
        }
    }

    dataBinding {

    }

}

设备:

apply plugin: 'com.android.library'

android {
    compileSdkVersion 27

    defaultConfig {
        minSdkVersion 21
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

    }

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

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

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation project(':domain')

    androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    implementation 'com.android.support:appcompat-v7:27.0.0'

    implementation 'io.reactivex.rxjava2:rxkotlin:2.1.0'
    implementation "com.squareup.retrofit2:retrofit:2.3.0"
    implementation "com.squareup.retrofit2:adapter-rxjava2:2.3.0"

    testImplementation 'junit:junit:4.12'
}

我不太确定这是怎么发生的。我尝试将 gradle 插件降级到 2.3.3，但没有成功。

有什么想法吗？

结果我在设备模块构建文件中遗漏了这一关键行:

apply plugin: 'kotlin-android'
