【问题描述】:
我正在尝试用 gradle 编译一个 kotlin 应用程序。该应用程序使用 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 我有:
import javafx.application.Application
import tornadofx.App
当我在 Windows 10 上编译这个项目时,无论是使用 gradle clean build 还是 .\gradlew clean build,它都能完美编译并运行。
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
...
虽然如果我从干净的设置中执行此操作,gradle 输出还包括:

这对我来说没有意义,因为它正确下载了依赖项(在 Linux 和 Windows 上),但只能在 Windows 而不是 Linux 上成功编译。我一直无法弄清楚发生了什么,所以任何人都可以提供任何关于在哪里看的建议吗?
【问题讨论】:
-
假设您使用的是 OpenJDK,JavaFX 默认不包含在 Oracle 的 JDK 中,因此您可能需要安装它或切换到 Oracle。
-
如果你在 Ubuntu 上,就像
sudo apt-get install openjfx一样简单
