import javax.validation.constraints.NotEmpty; not working [duplicate]

Question

I currently have a java/spring-boot application where I changed the version (in code) from 2.1.4 to 2.3.0 but as a result I've come across the error error: package javax.validation.constraints does not exist when trying to run a clean build - this comes from a import javax.validation.constraints.NotEmpty; line I have in my code - does anyone know how to resolve this issue to the code compiles/builds successfully?

Answer 1

The Validation Starter dependency is no longer included in the web starter dependencies. Therefore you need to add it manually to your gradle file:

  implementation 'org.springframework.boot:spring-boot-starter-validation'

This is mentioned in the release notes:
