如何使用Gradle Kotlin-DSL添加本地资源

Question

我试着用kotlin DSL测试5级。

Hasans-Air:blogiclib h_ajsf$ gradle init --type=kotlin-library

Starting a Gradle Daemon, 1 busy Daemon could not be reused, use --status for details

Select build script DSL:

1: groovy

2: kotlin

Enter selection (default: kotlin) [1..2] 2

Project name (default: blogiclib): 

Source package (default: blogiclib): 

**BUILD SUCCESSFUL** in 16s

2 actionable tasks: 2 executed

Hasans-Air:blogiclib h_ajsf$ ls

build.gradle.kts gradlew settings.gradle.kts

gradle gradlew.bat src

Hasans-Air:blogiclib h_ajsf$ code .

Hasans-Air:blogiclib h_ajsf$ gradle build

package blogiclib

class Library {
    fun someLibraryMethod(): Boolean {
        return true
    }
}

生成的build.gradle.kts是：

plugins {
    id("org.jetbrains.kotlin.jvm").version("1.3.10")
}

repositories {
    jcenter()
}

dependencies {
    implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8")
    testImplementation("org.jetbrains.kotlin:kotlin-test")
    testImplementation("org.jetbrains.kotlin:kotlin-test-junit")
}

然后我生成了一个kotlin app，测试如下：

Hasans-Air:gradle h_ajsf$ gradle init --type=kotlin-application

Starting a Gradle Daemon (subsequent builds will be faster)

Select build script DSL:

1: groovy

2: kotlin

Enter selection (default: kotlin) [1..2] 2

Project name (default: gradle): blogic

Source package (default: blogic): 

**BUILD SUCCESSFUL** in 25s

Hasans-Air:gradle h_ajsf$ ls

build.gradle.kts gradlew settings.gradle.kts

gradle gradlew.bat src

Hasans-Air:gradle h_ajsf$ code .

Hasans-Air:gradle h_ajsf$ gradle run
**BUILD SUCCESSFUL** in 6m 4s

3 actionable tasks: 3 executed

Hasans-Air:gradle h_ajsf$ gradle run

**> Task :run**

Hello world.

然后我将前面生成的libblogiclib.jar添加到文件夹:main\resources

package blogic

import blogiclib.LibraryKt

class App {
    val greeting: String
        get() {
            return "Hello world."
        }
}

fun main(args: Array<String>) {
    println("${App().greeting} = someLibraryMethod()")
}

plugins {
    id("org.jetbrains.kotlin.jvm").version("1.3.10")
    application
}

repositories {
    jcenter()
}

dependencies {
    implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8")
    testImplementation("org.jetbrains.kotlin:kotlin-test")
    testImplementation("org.jetbrains.kotlin:kotlin-test-junit")

}

application {
    mainClassName = "blogic.AppKt"
}

task<JavaCompile>("compile") {
    source = fileTree(file("src/main/resources/blogiclib.jar"))
}

Hasans-Air:gradle h_ajsf$ gradle run

e: /Users/h_ajsf/Documents/gradle/src/main/kotlin/blogic/App.kt: (6, 8): Unresolved reference: blogiclib

更新

根据收到的意见，我做了以下工作：

将库文件移动到文件夹src/main/libs:

将以下代码添加到build.gradle.kts:

而不是：

task<JavaCompile>("compile") {
    source = fileTree(file("src/main/resources/blogiclib.jar"))
}

但仍然得到相同的错误：（

Answer 1

您可以将所有jar文件包含在某些文件夹中，如下所示：

dependencies {
    implementation(fileTree("libs/compile"))
    compileOnly(fileTree("libs/provided"))
}

或者,选择特定文件：

repositories {
    flatDir {
        dirs("libs/compile")
        dirs("libs/provided")
    }
}

dependencies {
    implementation(":gson-2.8.5")
    compileOnly(":javaee-api-8.0")
}
