Try this,

Step-by-step:

  1. Open "build.gradle" file. It's in your root folder project;

  2. Include the line below inside "dependencies{ }": implementation group: 'javax.validation', name: 'validation-api', version: '2.0.1.Final'

  3. Save and close build.gradle file;

  4. Next, you will see a short notification on the top of your screen to "Load Gradle Changes". Click on it.

If you don't see any notification, click on Gradle side bar, and then click on "Reload All Gradle Projects".

  1. That's all! Your annotation @Valid, @NotBlank ou @NotNull, will work.

You just need to add spring-boot-starter-validation dependency in build.gradle file

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-validation'
}

You just need to add the dependency Validation API in the pom.xml:

<dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
    <version>2.0.0.Final</version>
</dependency>

If you get this error after attempting to import a Maven project, it may be that you need to check "Import Maven projects automatically" in the Import Project wizard. Without that the IntelliJ build may not be able to locate Maven dependencies, even if they are declared in pom.xml files.

Got it.

  1. File -> Project Structure
  2. In Modules click Dependecies, then click green "+" on the right side
  3. Click JARs or directiories... and add JAR files

  4. Click OK

    THEN:

  5. File -> Project Structure
  6. In Artifacts click FIX button on right bottom size
  7. Click OK

What build tool do you use? You obviously forgot to declare your dependencies, that's why IDEA doesn't know where to look for the classes you are trying to import.
