我正在Android项目中使用Kotlin测试Dagger 2。我受Android Clean Architecture回购的启发。我的gradle构建中有两个模块,一个是" app"一个是"模块"。模块包含一个类调用模型。在我的app gradle模块中,我创建了一个名为" DaggerModule"的Dagger模块。与模型提供者。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
当我尝试从"模块"移动Model类时模块到" app"模块一切都编译没有错误。试着弄清楚我是不是做了些蠢事,或者我是否应该在某个地方提交错误。
此处参考有问题文件的片段:

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。
答案 0 :(得分:10)
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"
}
