未解决的参考匕首2 + kotlin + android gradle

Question

我正在Android项目中用Kotlin测试Dagger 2.我受到了Android Clean Architecture回购的启发.我的gradle构建中有两个模块,一个是"app",另一个是"module".模块包含一个类调用模型.在我的app gradle模块中,我使用Model提供程序创建了一个名为"DaggerModule"的匕首模块.当我尝试构建项目时,出现编译错误:

DaggerModule.kt: (3, 57): Unresolved reference: Model 
DaggerModule.kt: (9, 34): Unresolved reference: Model
DaggerModule.kt: (9, 42): Unresolved reference: Model

当我尝试将Model类从"module"模块移动到"app"模块内部时,所有内容都编译为w/o错误.试图弄清楚我是在做一些愚蠢的事情,还是我应该在某个地方提交一个bug.

这里参考有问题的文件的片段:

app/build.gradle

buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }

//noinspection GroovyUnusedAssignment
targetCompatibility = 1.7

configurations {

    main {
        compileClasspath += configurations.provided
    }
}

}

DaggerModule.kt

Module
public class DaggerModule {
    Provides fun provideModel(): Model = Model()
}

----
Model.kt

public class Model { }

免责声明:这是我第一次尝试驾驶Dagger 2并且是一个gradle newb.示例项目是我可以找到的显示问题的最小代码.我不希望它做得太多:D.

您的module/build.gradle设置为java而不是kotlin.我已将其修改为以下内容并且编译正常.

buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'org.jetbrains.kotlin:kotlin-gradle-plugin:0.12.1218'
    }
}

apply plugin: 'kotlin'

dependencies {
    kapt "com.google.dagger:dagger-compiler:2.0.1"
    compile "com.google.dagger:dagger:2.0.1"
    compile "javax.annotation:javax.annotation-api:1.2"
    compile "org.jetbrains.kotlin:kotlin-stdlib:0.12.1218"
}
