Issue when defining a Binder about flow-crm-tutorial HOT 3 CLOSED

Hi,

Try changing the Binder field binder declaration from
Binder<Contact> binder = new BeanValidationBinder<>(Contact.class);
in ContactForm to
Binder<Contact> binder = new Binder<>(Contact.class);,

that did the trick for me!

from flow-crm-tutorial.

I googled more intensively and found a link re. that very same exception:
https://stackoverflow.com/questions/63879282/bean-instantiation-via-constructor-failed

So I added the dependency
<dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-validator</artifactId> <version>5.4.1.Final</version> </dependency>

to my pom.

But with that I get an
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'contactService': Invocation of init method failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'companyRepository' defined in com.vaadin.tutorial.crm.backend.repository.CompanyRepository defined in @EnableJpaRepositories declared on JpaRepositoriesRegistrar.EnableJpaRepositoriesConfiguration: Cannot resolve reference to bean 'jpaMappingContext' while setting bean property 'mappingContext'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jpaMappingContext': Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory; nested exception is org.hibernate.cfg.beanvalidation.IntegrationException: Error activating Bean Validation integration ...

(for whatever reason I am getting part of the error message in German... ||-( )

UnsupportedClassVersionError? F^%$@!

Here the fun stops! Any idea what version one can use? As mentioned I am using Java 11.

Strange enough the issue disappeared after a manual build on the command line (vs. the normal builds in my IDE). And it didn't resurface even after an "mvn clean" or manually cleaning out (removing all from) my local repository.
