I have a JavaFx project in which Maven install keeps giving me the error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.7.0:compile (default-compile) on project gui: Compilation failure: Compilation failure:

[ERROR] /C:/Users/digit/eclipse-workspace/gsn-notator/gui/src/main/java/gui/AppController.java:[21,19] package javafx.fxml does not exist

[ERROR] /C:/Users/digit/eclipse-workspace/gsn-notator/gui/src/main/java/gui/AppController.java:[29,17] cannot find symbol

[ERROR] symbol:   class FXMLLoader

[ERROR] location: class gui.AppController

[ERROR] /C:/Users/digit/eclipse-workspace/gsn-notator/gui/src/main/java/gui/AppController.java:[29,45] cannot find symbol

[ERROR] symbol:   class FXMLLoader

[ERROR] location: class gui.AppController

What am I doing wrong? How do I persuade Maven/Eclipse/Java/Whatever find the FXMLLoader?

The project structure has two modules, gui and logic, with the project structure in this tutorial. My overall project pom is:

<modules>

    <module>logic</module>

    <module>gui</module>

</modules>

<build>

    <plugins>

        <plugin>

            <groupId>org.apache.maven.plugins</groupId>

            <artifactId>maven-compiler-plugin</artifactId>

            <version>3.7.0</version>

            <configuration>

                <source>11</source>

                <target>11</target>

                <showWarnings>true</showWarnings>

                <showDeprecation>true</showDeprecation>

            </configuration>

            <dependencies>

                <dependency>

                    <groupId>org.ow2.asm</groupId>

                    <artifactId>asm</artifactId>

                    <version>6.2</version>

                </dependency>

            </dependencies>

        </plugin>

    </plugins>

</build>

The pom for the gui module is:

<parent>

    <groupId>com.gmail.digitig</groupId>

    <artifactId>gsn-notator</artifactId>

    <version>0.0.1-SNAPSHOT</version>

</parent>

<artifactId>gui</artifactId>

<dependencies>

    <dependency>

        <groupId>com.gmail.digitig</groupId>

        <artifactId>logic</artifactId>

        <version>${project.version}</version>

    </dependency>

    <dependency>  

        <groupId>org.openjfx</groupId>

        <artifactId>javafx-controls</artifactId>

        <version>11-ea+19</version>

    </dependency>

</dependencies>

I don't have anything in the logic module yet, other than a trivial module_info.java. Class gui.AppController, where the error is being reported, is:

package gui;



import java.io.IOException;

import javafx.fxml.FXMLLoader;

import javafx.scene.layout.BorderPane;



public class AppController extends BorderPane {

public AppController() {

    FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("App.fxml"));

    try {

        fxmlLoader.load();

    } catch (IOException exception) {

        throw new RuntimeException(exception);

    }

}

}

You need to include the dependency for javafx-fxml in your pom.xml:

<dependency>

    <groupId>org.openjfx</groupId>

    <artifactId>javafx-fxml</artifactId>

    <version>11.0.1</version>

</dependency>

and ensure the module-info.java has a requires directive for javafx.fxml module.

requires javafx.fxml;

Other suggestions:

• You can upgrade to the maven-compiler-plugin:3.8.0




• You can upgrade to javafx-controls:11.0.1
