Question

我正在尝试使用gradle编译kotlin应用程序。该应用程序使用tornadofx（kotlin版本的javafx）。

在build.gradle中，我有：

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
    compile 'no.tornado:tornadofx:1.7.8'
    compile 'com.squareup.moshi:moshi:1.5.0'
    compile 'com.squareup.moshi:moshi-kotlin:1.5.0'

    // Required for local unit tests (JUnit 4 framework)
    testCompile 'junit:junit:4.12'
}

在MyApp.kt我有：

import javafx.application.Application
import tornadofx.App

当我在Windows 10上使用gradle clean build或.\gradlew clean build编译此项目时，它会编译并完美运行。

当我在Ubuntu Linux上编译这个项目时，我收到一页错误消息，包括：

...

e: Supertypes of the following classes cannot be resolved. Please make sure you have the required dependencies in the classpath:
    class tornadofx.UIComponent, unresolved supertypes: javafx.event.EventTarget
    class tornadofx.App, unresolved supertypes: javafx.application.Application

...

e: /home/al/project/app/src/pcUi/MyApp.kt: (12, 5): Unresolved reference: Application

...

虽然如果我通过干净的设置执行此操作，但gradle输出还包括：

这对我来说没有意义，因为它正确地下载了依赖项（在Linux和Windows上），但之后只能在Windows而不是Linux上成功编译。我无法弄清楚发生了什么，所以有人可以提供任何建议吗？

Answer 1

请参阅错误消息：

e: /home/al/project/app/src/pcUi/MyApp.kt: (3, 8): Unresolved reference: javafx e: /home/al/project/app/src/pcUi/MyApp.kt: (12, 5): Unresolved reference: Application

好像你没有在Ubuntu上正确设置JDK。 JavaFX不再是OpenJDK的一部分，您必须手动安装它：https://packages.qa.debian.org/o/openjfx.html。

修改：请参阅https://stackoverflow.com/a/43301246/4697327。您可能正在使用包含JavaFX的Windows上的Oracle JDK。

Answer 2

为了快速在我的项目中重新包含 JavaFX，我修改了我的 build.grade 文件并让它同步。

plugins {
    id 'org.openjfx.javafxplugin' version '0.0.8'
}

repositories {
    mavenCentral()
}

javafx {
    version = "15.0.1"
    modules = [ 'javafx.controls', 'javafx.fxml' ]
}

Gradle Compilation在Linux上找不到tornadofx
