Poke me a finger how to build a javaFx application?

Question

Java

Good!
Here I rummage in Google, but I can’t find how to build an application from javaFx in IntelliJ IDEA. I somehow did something and started building 3 files, but there is no sense from them, one launches the terminal and turns off, the second - something java writes
ps. the application contains a gui, if it is important

I understand that the application is not signed, but how to sign it? or I do not understand correctly?

Answer 1

1) Create a Maven project
2) Specify in pom.xml that we will build the jar:

<groupId>Example</groupId>
    <artifactId>Example</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>jar</packaging>

2) Connect the plugin javafx-maven-plugin

<build>
        <plugins>
            <plugin>
                <groupId>com.zenjava</groupId>
                <artifactId>javafx-maven-plugin</artifactId>
                <version>2.0</version>
                <configuration>
                    <mainClass>тут пишем путь до вашего главного класса </mainClass>
                </configuration>
            </plugin>
        </plugins>
    </build>

3) We build the project with the mvn clean jfx:jar command, it will build the project in duplicate or select it through the Maven Projects menu.
5) Go to target /jpx/app - here lies the jar itself, and in target/jfx/app/lib - the libraries that were used in the project, when distributing, give both the jar and the “target/jfx/app/lib” folder " which should be next to the executable file.

Answer 2

Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.
