flow Production build fails if Spring Boot Application implements AppShellConfigurator and is annotated with a Spring Data JPA Repository

Description of the bug

If the application class is used as AppShellConfigurator as in the starter project, the production build fails with NoClassDefFoundError: org/springframework/context/ApplicationEventPublisherAware if the application class is also annotated with @EnableJpaRepositories.

This happens only with profile production, but fails in the prepare-frontend goal that is executed before build-frontend.

The exception itself comes probably from the fact that the AppShellConfigurator class (or any class that is annotated with @Theme) is annotated with @EnableJpaRepository, which imports JpaRepositoryFactoryBean that ultimately implements ApplicationEventPublisherAware. However, why the class cannot be found is not not clear to me. Its dependency spring-context is included in the compile scope.

ApplicationEventPublisherAware has many implementations in Spring Security too.

Expected behavior

No exception during production build.

Minimal reproducible example

Using the starter:

Include spring-data-jpa as dependency
Implements a class implementing Repository, e.g. public class TestRepository implements Repository<String, Integer>{}. Can be a static inner class of the Application class
Annotation Application with @EnableJpaRepositories(basePackageClasses = Application.TestRepository.class)

Execute mvn clean package -Pproduction and see the build fail.

My guess is that this happens because, even though the dependencies' scanner is using the project classpath, the maven plugin goal is executed within the plugin classpath.

Workaround should be moving the @EnableJpaRepositories on a separated @Configuration class

Jun 20 '24 13:06 mcollovati

Another workaround would be to implement a separate class for AppShellConfigurator

I had the exact same problem in December 2021 with vaadin-maven-plugin:9.0.0 . The workaround from that time still applies when you comment it back in:

Jul 24 '24 14:07 VISTALL

And yes, its repositoryFactoryBean. Moving @EnableJpaRepositories not helps, due it anyway analyzed, and throw exception

Jul 24 '24 14:07 VISTALL

Did you try my workaround, too?

Jul 24 '24 14:07 enver-haase

What I tested, and that not works:

move @EnableJpaRepositories to another configuration
extract AppShellConfigurator impl
adding context dependency to plugin

Now impossible build project, and I reverted upgrade. Also checked - due analyzer run on every annotated class, he will anyway throw exception on other class (all views, etc). Because #getAnnotationsByType() load all annotations

JDK code from Class

    @Override
    public <A extends Annotation> A[] getAnnotationsByType(Class<A> annotationClass) {
        Objects.requireNonNull(annotationClass);

        AnnotationData annotationData = annotationData(); // HERE we load all annotations
        return AnnotationSupport.getAssociatedAnnotations(annotationData.declaredAnnotations,
                                                          this,
                                                          annotationClass);
    }

Jul 24 '24 14:07 VISTALL

@VISTALL a couple of questions:

do you have optimizeBundle set to false in the plugin configuration?
looking at the stack trace it seems that the failure happens when visiting classes annotated with @NpmPackage. Since you already have a breakpoint where the exception is raised, can you inspect the stack at FullDependenciesScanner.discoverPackages:235 and confirm which is the offending class, and possibly, show its source code?

Jul 24 '24 14:07 mcollovati

@mcollovati Yes - optimizeBundle disabled, due project contains around 5 modules, and sometimes optimization make problems.

And yes.

Jul 24 '24 15:07 VISTALL

I can reproduce if I put a @NpmPackage and @EnableJpaRepositories on the same class implementing AppShellConfigurator. But once I move all Vaadin annotations to a separated class, the error does not happen anymore. The workaround works fine with both values of optimizedBundle.

Can you share the code of the Application class? Annotations and definitions should be enough, no need for the whole class.

Jul 24 '24 15:07 mcollovati

It's company code - not possible. But as you said. App implement AppShellConfigurator and @EnableJpaRepositories exists.

If I move implementation of AppShellConfigurator to another class (just for it) - problem persist.

@SpringBootApplication(scanBasePackages = ?")
@EnableCaching
@EnableScheduling
@Push(value = PushMode.MANUAL, transport = Transport.WEBSOCKET)
@EntityScan(basePackages = "?")
@EnableJpaRepositories(basePackages = "?")
@Theme("?")
@NpmPackage(value = "@fortawesome/fontawesome-free", version = "6.4.0")
@ComponentScan(excludeFilters = @ComponentScan.Filter(type = FilterType.REGEX, pattern = "?"))
@Uses(RadioButtonGroup.class)
@Uses(TextArea.class)
@Uses(ApexCharts.class)
@Uses(Accordion.class)
@Uses(DateTimePicker.class)
@Uses(ComboBox.class)
@Uses(NumberField.class)
@Uses(Checkbox.class)
@Uses(ProgressBar.class)
@Uses(Button.class)
@Uses(IntegerField.class)
@Uses(ColorPicker.class)
@Uses(AceEditor.class)
@Uses(ToggleButton.class)
@Uses(VirtualList.class)
@Uses(Upload.class)
@Uses(TinyMce.class)
@JsModule("./clipboard/clipboard.js")
@NpmPackage(value = "@esotericsoftware/spine-player", version = "4.1.51")
@StyleSheet("@esotericsoftware/spine-player/dist/spine-player.min.css")
public class Application implements AppShellConfigurator {

@Uses from logic when optimization enabled, and there some implicit dependencies exists (like plugins). Legacy - just need remove it :D

Jul 24 '24 15:07 VISTALL

Moving all Vaadin annotations to another class seems to work. Give the above snippet it would be like

@SpringBootApplication(scanBasePackages = ?")
@EnableCaching
@EnableScheduling
@EntityScan(basePackages = "?")
@EnableJpaRepositories(basePackages = "?")
@ComponentScan(excludeFilters = @ComponentScan.Filter(type = FilterType.REGEX, pattern = "?"))
public class Application {

and

@Push(value = PushMode.MANUAL, transport = Transport.WEBSOCKET)
@Theme("?")
@NpmPackage(value = "@fortawesome/fontawesome-free", version = "6.4.0")
@Uses(RadioButtonGroup.class)
@Uses(TextArea.class)
@Uses(ApexCharts.class)
@Uses(Accordion.class)
@Uses(DateTimePicker.class)
@Uses(ComboBox.class)
@Uses(NumberField.class)
@Uses(Checkbox.class)
@Uses(ProgressBar.class)
@Uses(Button.class)
@Uses(IntegerField.class)
@Uses(ColorPicker.class)
@Uses(AceEditor.class)
@Uses(ToggleButton.class)
@Uses(VirtualList.class)
@Uses(Upload.class)
@Uses(TinyMce.class)
@JsModule("./clipboard/clipboard.js")
@NpmPackage(value = "@esotericsoftware/spine-player", version = "4.1.51")
@StyleSheet("@esotericsoftware/spine-player/dist/spine-player.min.css")
public class AppShell implements AppShellConfigurator {

Jul 24 '24 15:07 mcollovati

And. Looks like it helps. Thanks. Ambiguous problem, code was legal before update (and there no info about limitation)

Jul 24 '24 15:07 VISTALL

It looks like that in 24.3 the class scan is not performed during prepare-frontend, whereas it is done in 24.4. I have to check if this has been changed on purpose or if it is a regression caused by #19011

Jul 24 '24 16:07 mcollovati

Will be nice to see fix in near future :)

Jul 24 '24 17:07 VISTALL

Just as a short info: I have updated to Vaadin Version 24.4.8 yesterday and have still the exact same error as decribed above. Using only the Annotations @EnableJpaRepositories and @EntityScan

So hopefully a fix will come in near future :)

Aug 08 '24 07:08 mo-jo

I fixed this issue with two main steps. First, I created an AppShell class, extending AppShellConfigurator. I put all the Vaadin related annotations from the app class into it. Next, I went into /.m2/repository and deleted everything. After doing that, I ran mvn clean install, which succeeded and then I ran the app with mvn spring-boot:run and it started up as expected.

Aug 13 '24 14:08 sfbell09

Moving @EnableJpaRepositories to another class with @Configuration worked for me as a workaround using 24.4.10 - but would be nice for there to be a proper fix for this given the impact.

Aug 27 '24 03:08 dolukhanov

Let us prioritise this for next dev iteration (next two weeks). Stay tuned.

Sep 26 '24 10:09 mshabarov

The issue was triaged and currently added to the backlog priority queue for further investigation.

Oct 23 '24 07:10 mshabarov

This ticket/PR has been released with Vaadin 24.4.18.
