Does not start

The project cannot run; it stops with

[ERROR] Source option 6 is no longer supported. Use 8 or later.
[ERROR] Target option 6 is no longer supported. Use 8 or later.

If you change the version to 1.8 in the pom.xml, it fails because of

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class: file [/Users/matteo/Documents/work/dojo/2024-03-01-thymeleaf-pet-clinic/thymeleafexamples-petclinic/target/classes/org/springframework/samples/petclinic/service/ClinicService.class]; nested exception is org.springframework.core.NestedIOException: ASM ClassReader failed to parse class file - probably due to a new Java class file version that isn't supported yet: file [/Users/matteo/Documents/work/dojo/2024-03-01-thymeleaf-pet-clinic/thymeleafexamples-petclinic/target/classes/org/springframework/samples/petclinic/service/ClinicService.class]; nested exception is java.lang.IllegalArgumentException

I tried with openjdk version 8, 11 and 21. Same results.

I'm running maven 21.0.2
