Prepare the environment for java11 and javaFx with Ubuntu 18.4

environment

ubuntu

___@kubuntu:~$ lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 18.04.1 LTS
Release:	18.04
Codename:	bionic

If you put java, it will be like this

___@kubuntu:~$ java --version
opensdk 11.0.1 2018-10-16
OpenJDK Runtime Environment 18.9 (build 11.0.1+13)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.1+13, mixed mode)

___@kubuntu:~$ javac --version
javac 11.0.1

Install openjdk

As of November 18, 2018, if you install openjdk-11-jdk with apt, openjdk10 will be installed. It seems to switch in the future

This time install java11 using sdkman

1. You can install sdkman just by following https://sdkman.io/install
2. You can install java11 just by following https://sdkman.io/sdks
3. Check with java --version and javac --version

The main body of java when installed with sdkman

/home/username/.sdkman/candidates/java/11.0.1-open

It is in

Write the path here when specifying jdk in Intellij etc.

Download javaFx

1. Download from https://openjfx.io/

This time I decided to place it in / opt

/opt/openjfx-11.0.1_linux-x64_bin-sdk/
└── javafx-sdk-11.0.1
    ├── legal
    ...Abbreviation
    └── lib
    ...Abbreviation

Run with intellij

Create a javafx project

How to make it with reference to others

Setting that does not use gradle this time

1. Write the code appropriately. Some sample is fine

2. Press [Main ▼] on the upper left to open edit configurations

3. Write settings such as jdk

4. Set the VM Option as follows

--module-path=/opt/openjfx-11.0.1_linux-x64_bin-sdk/javafx-sdk-11.0.1/lib
--add-modules=javafx.controls
--add-modules=javafx.swing
--add-modules=javafx.base
--add-modules=javafx.fxml
--add-modules=javafx.media
--add-modules=javafx.web

1. Press OK
2. Execute with Shift + F10

Addictive point

If you search normally on the net, there are many articles that contain only javafx.controls, which is incomplete, In that state, the following exception will appear, so include all modules
