测试包不读取主包中定义的Kotlin类

Question

我似乎无法访问Android Studio项目中我的Kotlin模块中的测试包中的主类。 请注意，下面显示的所有代码都在导入Android应用程序的Kotlin JVM模块中。

这是我的src/main/java代码：

import com.google.gson.annotations.SerializedName

data class Customer(val password1: String,
                val password2: String,
                @SerializedName("last_name") val lastName: String,
                @SerializedName("first_name") val firstName: String,
                val email: String)

我在src/test/java测试代码：

class CreateUser {

    @Test
    fun createRandomUser() {
        val random = Random()
        val randomNumber = random.nextInt(10000000)
        val customer = Customer("password", "password", "lastName", "firstName", "ted$randomNumber@gmail.com")

    }
}

我的build.gradle代码如下所示：

buildscript {
    ext.kotlin_version = '1.1.4-3'
    repositories {
        mavenCentral()
        jcenter()
    }
    dependencies {
        classpath 'me.tatarka:gradle-retrolambda:3.7.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

apply plugin: 'java'
apply plugin: 'maven'
apply plugin: 'me.tatarka.retrolambda'
apply plugin: 'kotlin'

repositories {
    mavenCentral()
    jcenter()
}

dependencies {
    // some other compile dependencies
    compile "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"

    testCompile "org.hamcrest:hamcrest-all:1.3"
    testCompile 'junit:junit:4.11'
    testCompile 'org.mockito:mockito-all:1.9.5'
    testCompile "org.jetbrains.kotlin:kotlin-test"
    testCompile "org.jetbrains.kotlin:kotlin-test-junit"
}

task javadocJar(type: Jar) {
    classifier = 'javadoc'
    from javadoc
}

task sourcesJar(type: Jar) {
    classifier = 'sources'
    from sourceSets.main.allSource
}

artifacts {
    archives sourcesJar
    archives javadocJar
}

compileKotlin {
    kotlinOptions {
        jvmTarget = "1.6"
    }
}
compileTestKotlin {
    kotlinOptions {
        jvmTarget = "1.6"
    }
}

root build.gradle文件如下所示：

// Top-level build file where you can add configuration options 
common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://jitpack.io"
            credentials { username authToken }
        }
    }
}

task clean(type: Delete) {
     delete rootProject.buildDir
}

ext {
    versionName = "0.1.1"
    rxJavaVersion = "2.1.3"
    okHttpVersion = "3.9.0"
    retrofitVersion = "2.3.0"
    rxJava2AdapterVersion = "1.0.0"
    googleGsonVersion = "2.8.0"
}

我得到的错误是gradle无法解析Test类中的Customer （ Unresolved reference: Customer ）。 它似乎没有将主类包含到测试源目录中。 然而，它在IDE中解决了。

好的，我找到了解决方案。 看来我必须在build.gradle中明确指定src文件夹，并将所有Kotlin代码分别放在src/main/kotlin和src/test/kotlin 。

sourceSets {
    main.kotlin.srcDirs = ['src/main/kotlin', 'src/main/java']
    main.java.srcDirs = []
    test.kotlin.srcDirs = ['src/test/kotlin', 'src/test/java']
    test.java.srcDirs = ['src/test/kotlin', 'src/test/java']
}

一旦我这样做，测试开始按预期工作 - 甚至在Jenkins上生成报告，这很好。
