Bug: Spring Boot 3.0.0-M1 cannot find javax.validation

[imryao]

Hi there! I've found something working unexpectedly when I test Spring Boot 3.0.0-M1.

My project uses spring-boot-starter-validation as its bean validator. When I upgraded spring-boot-starter-parent version to 3.0.0-M1, mvn clean package failed and reported package javax.validation does not exist. After I rollback to 2.6.3, it just worked properly.

Here's my pom.xml:

Can you have a look into it? Thanks!

Could you have a look at the release notes? 3.0.0 is going to be a major release with important changes.

In the case of your application I can see already that it should upgrade to JDK 17, Jakarta validation (instead of javax validation). Also I don't think the Spring Cloud version or mybatis starter version you are using will be compatible here.

¿Podrías echar un vistazo a las notas de la versión ? 3.0.0 va a ser un lanzamiento importante con cambios importantes.

En el caso de su aplicación, ya puedo ver que debería actualizarse a JDK 17, validación de Jakarta (en lugar de validación javax). Además, no creo que la versión de Spring Cloud o la versión de inicio de mybatis que está utilizando sean compatibles aquí.

Pasar a jakarta soluciono mi problema. Muchas gracias
