Problems/Solutions

• JTE seems to find project classes only (on jte pre-compilation)
• Caused by: java.io.FileNotFoundException: class path resource [org/springframework/boot/autoconfigure/web/servlet/WebMvcRegistrations.class] cannot be opened because it does not exist
• class is in: spring-boot-autoconfigure
• using spring-boot parent 3.2.3 does start only without any spring libraries jte and htmx. the spring depenendency plugin must be removed either.
