Ubuntu 18.04 javafx.utils 不存在

Question

我正在尝试“构建”泛光灯。 我偶然发现了相当不言自明的编译问题，即：

> compile:
>     [javac] Compiling 593 source files to /mnt/sda1/floodlight/floodlight/target/bin
>     [javac] warning: [options] bootstrap class path not set in conjunction with -source 8

[等等]

我当然尝试过像这样通过 apt 添加 javafx ：

root@hp-linux: apt install openjfx

root@hp-linux:/mnt/sda1/floodlight/floodlight# dpkg-query -L openjfx
/.
/usr
/usr/share
/usr/share/doc
/usr/share/doc/openjfx
/usr/share/doc/openjfx/TODO.Debian
/usr/share/doc/openjfx/changelog.Debian.gz
/usr/share/doc/openjfx/copyright
/usr/share/openjfx
/usr/share/openjfx/lib
/usr/share/openjfx/lib/javafx.properties
/usr/share/openjfx/lib/javafx.base.jar
/usr/share/openjfx/lib/javafx.controls.jar
/usr/share/openjfx/lib/javafx.fxml.jar
/usr/share/openjfx/lib/javafx.graphics.jar
/usr/share/openjfx/lib/javafx.media.jar
/usr/share/openjfx/lib/javafx.swing.jar
/usr/share/openjfx/lib/javafx.web.jar

似乎确实不存在 javafx.utils 。 我该如何解决？ 我已经尝试了几乎所有可以在 Internet 上找到的东西，但无济于事。

由于上游不再支持 openjfx，Ubuntu 18.04 决定不再支持 openjfx 8 并将其替换为 openjfx 11。如果您是 SDN 人，您应该知道 Floodlight 支持 Java 8 等问题会在这里找到。 我现在分享了一个帖子，希望能对你有所帮助。 如何在 Ubuntu 18.04 LTS 上与 Openjfx 一起安装泛光灯 controller
