Developing Your First Spring Boot Application section asks the user to create the application in the root package

https://github.com/spring-projects/spring-boot/blob/v3.4.2/spring-boot-project/spring-boot-docs/src/docs/antora/modules/tutorial/pages/first-application/index.adoc

run a simple demo project step by step with the doc below, a error occur:

java.lang.ClassNotFoundException:org.springframework.dao.DataAccessException

The #1839 tell me that should not put main method in the default package. maybe we should update the doc?

Thanks for the report. Two things are going on here

1. We were supposed to have a com.example package but it looks like it's gone in recent versions. Perhaps a regression of the move to Antora?
2. In all cases we instruct the users to create a source file in src/main/java/MyApplication.java which is wrong given the package statement.

This rings a bell indeed.

Point 2 from @snicoll's comment is resolved by #43965.

For point 1 above, there are a couple of problems:

• A block-level chomp_package_replacement attribute is ignored
• include-code does not transfer the chomp_package_replacement attribute to the blocks that it creates.

Both of these will have to be addressed in https://github.com/spring-io/asciidoctor-extensions. I'm working on that now.

This is now blocked on:

• Block attributes are ignored when determining chomp package replacement spring-io/asciidoctor-extensions#24
• Blocks for included code lose attributes declared on the macro spring-io/asciidoctor-extensions#25

#43982 should have unblocked this issue
