Trouble with gwt validation

Question

I am trying to use gwt valiation module (jsr303) using new validation-api (1.1) and Hibernate validator (5.0), but, obvious got

ERROR: Errors in 'file:/C:/projects/qiwi-digest/webui/trunk/src/main/java/ru/befree/qiwi/client/gin/SampleValidatorFactory.java'
  ERROR: Line 27: No source code is available for type javax.validation.ParameterNameProvider; did you forget to inherit a required module?
  ERROR: Line 27: The method getParameterNameProvider() of type SampleValidatorFactory must override or implement a supertype method
  ERROR: Line 28: No source code is available for type org.hibernate.validator.internal.engine.DefaultParameterNameProvider; did you forget to inherit a required module?
  ERROR: Line 32: The method close() of type SampleValidatorFactory must override or implement a supertype method

I.e. GWT currently doesn't have Validation API 1.1 support.

Any ideas of workaround?

You are probably ahead of the curve in using Hibernate 5!!!!

GWT supports only upto hibernate 4.1.0.Final . Here is the snipped of maven pom.xml from GWT sample for Validation.

   <!-- Hibernate bean validation binary for the server -->

    <dependency>
      <groupId>org.hibernate</groupId>
      <artifactId>hibernate-validator</artifactId>
      <version>4.1.0.Final</version>
      <exclusions>
        <exclusion>
          <groupId>javax.xml.bind</groupId>
          <artifactId>jaxb-api</artifactId>
        </exclusion>
        <exclusion>
          <groupId>com.sun.xml.bind</groupId>
          <artifactId>jaxb-impl</artifactId>
        </exclusion>
      </exclusions>
    </dependency>

    <!-- Hibernate bean validation source for the GWT client -->

    <dependency>
      <groupId>org.hibernate</groupId>
      <artifactId>hibernate-validator</artifactId>
      <version>4.1.0.Final</version>

        </exclusion>
        <exclusion>

    </dependency>

GWT has ported hibernate validator code to work with client side. You can find it here - https://code.google.com/p/google-web-toolkit/source/browse/trunk/user/src/org/hibernate/validator

You can try hacking around this to support hibernate 5 and validation-api 1.1 !!!
