Hi @mauromol,
The syntax used in the Spring tutorial is added by the ‘io.spring.dependency-management’ plugin. That plugin is available for a long time and was created before Gradle introduced support for BOMs in the core (the platform keyword). We are working with the Spring team to clarify the situation and to update documentation. But it might still take some time.
The recommendation is already:
If you do not need anything specific from the ‘io.spring.dependency-management’ plugin, you do not need to use it anymore. And you can/should use platform(). And not apply the plugin even though it is mentioned in the tutorial.
