JavaFx 12 Spring, Maven No plugin found for prefix - spring

I have a problem trying to debug a project with javafx and spring
my pom. xml

I have these errors when trying to compile with maven:

I went to run configurations and make this:

Answer 1

The pom you have posted is missing the javafx-maven-plugin. As documented here: https://openjfx.io/openjfx-docs/#IDE-Eclipse (Maven section), you need to include it in order to deal with the JavaFX dependencies (including them in the module-path, adding the required modules), while keeping the rest of dependencies in the classpath (if your project is non-modular).
And if you want to run the goal javafx:run, as posted in the picture, you do need the plugin that defines this goal.
This works for me (JavaFX + Spring):
POM
<?xml version="1.0" encoding="UTF-8"?>

</project>
Main class
package org.openjfx;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ConfigurableApplicationContext;
#SpringBootApplication
public class MainApp extends Application {
private ConfigurableApplicationContext springContext;
private FXMLLoader fxmlLoader;
#Override
public void init() throws Exception {
springContext = SpringApplication.run(MainApp.class);
fxmlLoader = new FXMLLoader();
fxmlLoader.setControllerFactory(springContext::getBean);
}
#Override
public void start(Stage stage) throws Exception {
fxmlLoader.setLocation(getClass().getResource("scene.fxml"));
Parent root = fxmlLoader.load();
Scene scene = new Scene(root);
scene.getStylesheets().add(getClass().getResource("styles.css").toExternalForm());
stage.setTitle("JavaFX and Maven");
stage.setScene(scene);
stage.show();
}
#Override
public void stop() {
springContext.stop();
}
public static void main(String[] args) {
launch(args);
}
}
FXMLController
package org.openjfx;
import org.springframework.stereotype.Controller;
#Controller
public class FXMLController {
public void initialize() {
// TODO
}
}
Now you can run from the console:
mvn clean javafx:run
or add a goal to Run configurations -> Maven Build: clean javafx:run.
You should see your JavaFX app working, and also the Spring output:
