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

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;
