Answer 1

As @Korgen mentioned in comments hibernate-validator-5.x.x isn't compatible with validation-api-1.0.x. This is because of moving to new specification JSR-303 -> JSR-349.

There are two ways to solve this issue:

1. Downgrade hibernate validator version (which is implements JSR-303):

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>4.3.1.Final</version>
</dependency> 

2. If you don't want to move back from hibernate validator 5 to hibernate validator 4 another solution is to upgrade javax.validation to higher version (which is describe JSR-349):

<dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
    <version>1.1.0.Final</version>
</dependency>

Answer 2

For those who got error NoClassDefFoundError: javax/validation/valueextraction/ValueExtractorDeclarationException and their validation-api was already javax.validation:validation-api:1.1.0.Final

The fix was to upgrade from javax.validation:validation-api:1.1.0.Final to javax.validation:validation-api:2.0.1.Final.
