How do I import javax.validation into my Java SE project?

Question

I\'m trying to add constraints checking, as described here How to specify the cardinality of a @OneToMany in EclipseLink/JPA

The dependencies as of 2019:

    org.hibernate.validator
    hibernate-validator
    6.0.16.Final

This transitively pulls in the dependency to the Bean Validation API, so you don't need to do this anymore:

    javax.validation
    validation-api
    1.1.0.Final

For additional features, Expression Language and CDI support, you might need to add:

    org.glassfish
    javax.el
    3.0.1-b09



    org.hibernate.validator
    hibernate-validator-cdi
    6.0.16.Final

Source: Hibernate Validator documentation

These are all in Maven Central Repo, so you don't need to add the JBoss repo.

And BTW here's my example convenience method:

public static  void  validate( T object ) throws MigrationException
{
    ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
    Validator validator = factory.getValidator();
    Set> valRes = validator.validate( object );
    if( ! valRes.isEmpty() )
    {
        StringBuilder sb = new StringBuilder("Validation failed for: ");
        if( object instanceof Origin.Wise )
            sb.append( ((Origin.Wise)object).getOrigin() );
        else
            sb.append(object);

        for( ConstraintViolation fail : valRes)
        {
            sb.append("\n  ").append( fail.getMessage() );
        }
        throw new IllegalArgumentException( sb.toString() );
    }
}

The Origin.Wise is something like JAXB's @XmlLocation Locator.
