Gradle編譯在Linux上找不到tornadofx

Question

我想用gradle編譯一個kotlin應用程序。該應用程序使用tornadofx（javafx的kotlin版本）。

在build.gradle，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：

import javafx.application.Application 
import tornadofx.App 

當我在Windows上編譯10這個項目，無論是與gradle clean build或.\gradlew clean build，它編譯和完美的作品。

當我編譯在Ubuntu Linux這個項目，我得到錯誤信息的頁面，其中包括：

... 

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 

... 

雖然如果我這樣做，從一個乾淨的設置，在gradle這個輸出還包括：

這對我來說沒有任何意義，因爲它正確地下載了依賴關係（在Linux和Windows上），但是隻能成功地在Windows而不是Linux上編譯。我一直無法弄清楚發生了什麼，所以任何人都可以提供任何建議，看看哪裏？

看到錯誤消息：

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

好像你沒有你的JDK正確設置在Ubuntu做。 JavaFX不再是OpenJDK的一部分，您必須手動安裝它：https://packages.qa.debian.org/o/openjfx.html。

編輯：見https://stackoverflow.com/a/43301246/4697327。您可能在Windows上使用了Oracle JDK，其中包含JavaFX。
