spring-boot-starter-web hibernate-validator depend

I created spring boot project(Spring starter project) on STS(Spring tool suit), both of Window and Mac. Here is my pom.xml:

</project>

Some of the dependency hierarchies are missing on Mac.

Example :

hibernate-validator

validation-api (missing on Mac)
jboss-loggin (missing on Mac)
classmate (missing on Mac)

I need that jars on Mac without modifying pom.xml. I think I miss some environment Mac.

And I bought Mac 2 days ago. It's my first Mac.

If you want to use Hibernate Validator, you need to include it as explicit dependency:

    <dependency>
        <groupId>org.hibernate.validator</groupId>
        <artifactId>hibernate-validator</artifactId>
    </dependency>

Notice we don't specify version as Spring Boot will take care of it.

Other option is to use validation starter provided by Spring Boot:

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-validation</artifactId>
    </dependency>

Concerning your Windows/MacOS specific problems, it is some kind of misunderstanding. You need dependencies I mentioned. If you include them, it will work the same way on both platforms.
