Could not resolve placeholder for JavaFX application with Spring Boot - spring

Question

I have a problem using Spring boot with JavaFX. I have the following error when starting my new application:
Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'spring.application.ui.title' in value "${spring.application.ui.title}"
I follow this tutorial: https://blog.jetbrains.com/idea/2019/11/tutorial-reactive-spring-boot-a-javafx-spring-boot-application/ to create it.
So here are my classes:
#SpringBootApplication
public class AgricultureApplication {
public static void main(String[] args) {
Application.launch(ApplicationStartUp.class,args);
}
}
public class ApplicationStartUp extends Application {
private ConfigurableApplicationContext applicationContext;
#Override
public void init() {
applicationContext = new SpringApplicationBuilder(AgricultureApplication.class).run();
}
#Override
public void stop(){
applicationContext.close();
Platform.exit();
}
#Override
public void start(Stage primaryStage){
applicationContext.publishEvent(new StageReadyEvent(primaryStage));
}
public static void main(String[] args) {
launch(args);
}
}
#Component
public class StageInitializer implements ApplicationListener<StageReadyEvent> {
private final String applicationTitle;
private ApplicationContext applicationContext;
public StageInitializer(#Value("${spring.application.ui.title}") String applicationTitle, ApplicationContext applicationContext){
super();
this.applicationTitle = applicationTitle;
this.applicationContext = applicationContext;
}
#Override
public void onApplicationEvent(StageReadyEvent stageReadyEvent) {
final Stage primaryStage = stageReadyEvent.getStage();
try {
FXMLLoader fxmlLoader = new FXMLLoader(new ClassPathResource("/main.fxml").getURL());
fxmlLoader.setControllerFactory(aClass -> applicationContext.getBean(aClass));
Parent parent = fxmlLoader.load();
Scene scene = new Scene(parent);
primaryStage.setResizable(false);
primaryStage.setScene(scene);
primaryStage.setTitle(applicationTitle);
primaryStage.show();
}
catch (IOException e) {
e.printStackTrace();
}
}
}
public class StageReadyEvent extends ApplicationEvent {
public StageReadyEvent(Stage stage) {
super(stage);
}
public Stage getStage() {
return (Stage) this.getSource();
}
}
This is application.properties file:
spring.datasource.url=jdbc:h2:file:./AgricultureRentDb
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=sa
spring.datasource.password=
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
spring.main.web-application-type=none
spring.application.ui.title = "Test"
spring.h2.console.enabled=true
And my POM.xml:

Here is my project strucutre:
I think spring doesn't recognize application.properties file and i do not why, i've tried to add even the #PropertySource annotation and put absolute path to the application.properties file or to put it as classpath.
Just for notice that when i follow the tutorial i am using java 8 instead of java 11, but i do not think that's making the problem.
EDITED:
Here is my github link for the project: https://github.com/Dilyan-Galabov/Agriculture
Can you please help me to provide the problem, thank you in advance :)!

Firstly #James_D found there is a problem copying the resources files to the target folder. Actually they are not copied anyway even if i add this to my pom.xml:
<resources>
<resource>
<directory>src/main/resources</directory>
<targetPath>${project.build.outputDirectory}</targetPath>
<includes>
<include>**/*.*</include>
</includes>
</resource>
</resources>
Even if i try to set different targetPath the problem occurs(doesn't copying the files to targetPath) and actually i think that maven does not read that code in the pom and i do not know why this is happening.
