如何修复未解析的参考：javafxplugin？

Question

如何应用插件来JavaFX使用 Kotlin DSL？手册建议：

apply plugin: 'org.openjfx.javafxplugin'

而我使用的是 Gradle Kotlin DSL，而不是普通的 Gradle。

当前错误：

application {

    mainClassName = "net.bounceme.dur.fx.App"

val test by tasks.getting(Test::class) {
    // Use TestNG for unit tests
    useTestNG()
}

我正在寻找从 JavaFX 运行示例。

Answer 1

Gradle 插件门户提供了在 Groovy 和 Kotlin 中声明插件的示例。GitHub 存储库的 README还提供了每种语言的示例。基本上，应用该插件如下所示：

plugins {
    application // built-in plugins are declared differently
    id("org.openjfx.javafxplugin") version "0.0.7"
}

然后要添加您需要的 JavaFX 模块，您可以使用：

javafx {
    // will pull in transitive modules
    modules("javafx.controls", "javafx.fxml") // replace with what you modules need

    // another option is to use:
    // modules = listOf("javafx.controls", "javafx.fxml")

    version = "12.0.1" // or whatever version you're using
}

repositories {
    mavenCentral() // I believe jcenter() should work as well
}

上面的代码将为运行 Gradle 守护进程的操作系统引入javafx.base、javafx.graphics、javafx.controls和模块。javafx.fxml它将它们添加到implementation配置中。不要手动声明任何 JavaFX 依赖项。

注意：该org.openjfx.javafxplugin插件还应用了com.google.osdetector和org.javamodularity.moduleplugin插件；至少，它在版本中是这样的0.0.7。

构建文件的其余部分将类似于：

java {
    // replace with the Java version you're using
    sourceCompatibility = JavaVersion.VERSION_11
    targetCompatibility = JavaVersion.VERSION_11
}

application {
    mainClassName = /* your main class */
}

dependencies {
    // add your other dependencies
}

tasks {
    test {
        useTestNG()
    }
}

Gradle Kotlin DSL Primer页面是 Kotlin DSL 的一个很好的起始资源。如果您是 Kotlin 新手，我建议您阅读参考文档。
