gradle - 如何使用 Gradle 编译 Kotlin 域模块和客户端模块？

Question

我有以下项目结构:
- 父
- - client(用 Kotlin 编写，但编译为 JS)
- - 服务器(用 Kotlin 编写)
- - 模型(用 Kotlin 编写)
client 模块依赖于model。因此，当我将 client 编译为 JS 时，它也应该用它来编译 model 。现在我有以下 Gradle 配置，但没有完成所需的操作:

project/parent.gradle

group 'com.vchernogorov.tycher'
version '1.0-SNAPSHOT'

buildscript {
    ext.kotlin_version = '1.1.3-2'

    repositories {
        mavenCentral()
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

apply plugin: 'kotlin'

repositories {
    mavenCentral()
}

dependencies {
    compile "org.jetbrains.kotlin:kotlin-stdlib-jre8:$kotlin_version"
    compile project(":model")
    compile project(":client")
    compile project(":server")
}

compileKotlin {
    kotlinOptions.jvmTarget = "1.8"
}
compileTestKotlin {
    kotlinOptions.jvmTarget = "1.8"
}

项目/settings.gradle

rootProject.name = 'parent'
include ':model'
include ':server'
include ':client'

项目/模型/build.gradle

group 'com.vchernogorov.tycher'
version '1.0-SNAPSHOT'

buildscript {
    ext.kotlin_version = '1.1.3-2'

    repositories {
        mavenCentral()
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

apply plugin: 'kotlin'

repositories {
    mavenCentral()
}

dependencies {
    compile "org.jetbrains.kotlin:kotlin-stdlib-jre8:$kotlin_version"
}

compileKotlin {
    kotlinOptions.jvmTarget = "1.8"
}
compileTestKotlin {
    kotlinOptions.jvmTarget = "1.8"
}

project/client/build.gradle

group 'com.vchernogorov.tycher'
version '1.0-SNAPSHOT'

buildscript {
    ext.kotlin_version = '1.1.3-2'

    repositories {
        mavenCentral()
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

apply plugin: 'kotlin2js'

repositories {
    mavenCentral()
}

dependencies {
    compile "org.jetbrains.kotlin:kotlin-stdlib-js:$kotlin_version"
    compile project(":model")
}

build.doLast {
    configurations.compile.each { File file ->
        copy {
            includeEmptyDirs = false

            from zipTree(file.absolutePath)
            into "${projectDir}/web"
            include { fileTreeElement ->
                def path = fileTreeElement.path
                path.endsWith(".js") && (path.startsWith("META-INF/resources/") || !path.startsWith("META-INF/"))
            }
        }
    }
}

当我在 client 上运行 gradle build 命令时，我收到以下消息:

:model:compileKotlin

这3个类在model中定义。
那么我应该怎么做才能成功编译 client 并且不更改代码呢？

Answer 1

我为我的应用程序开发了以下架构: 我有client , server和model模块，而且我还有一个带有 DTO 的单独源目录，名为 dto (顺便说一句，不是模块)。这是构建的依赖关系层次结构:

• client取决于dto
• server取决于model
• model取决于dto

有了这样的层次结构模型仍然可以使用stdlib功能和server将与 client 共享所有 DTO模块。同时dto模块将使用stdlib如果编译为 module依赖性和stdlib-js如果编译为 client依赖性，因此记住您可以在那里使用哪些类很重要。

为了实现这一点，您需要添加

sourceSets.main.kotlin.srcDirs += '../dto/src/main/kotlin

配置为client和model构建.gradle 文件。对于 Gradle Kotlin DSL:

the<JavaPluginConvention>().sourceSets {
    "main" {
        java {
            srcDirs("../dto/src/main/kotlin")
        }
    }
}
