---------------------------------------

@Joachim, @Michael please be nice to one another :)

I have described our usecase in https://jira.qos.ch/browse/SLF4J-365 which got closed as won't fix for beeing to much effort. I believe Ceki already sees the value of that feature for users of slf4j (at least he stated it makes sense in LOGBACK-1157). By providing examples and an alternative implementation I hope to have lowered the burden of creating an initial BOM. Maybe if more users see the value in BOMs this issue will get somewhere.

@Joachim: Let me explain the advantage of a BOM for us with an example:

-------------------------------------------------------------------------------------------------------

Example: slf4j adds another module, or renames a module.

Without BOM every project will have to carefully read the releasenotes and then add another entry to their (parent-)pom where the slf4js modules are listed and add/rename a module. In big companys this might be centralized so that you have to do this for a lot of libraries. It's a tedious and error prone task.

With BOM every project just raises the version of the BOM in the (parent-)pom to the latest and automatically ensures that all module versions are managed. This is quite convenient and also helps to keep our parent-pom at a somewhat manageable size.

There are more examples like just increasing the version, or dropping a module where the same logic applies. @Joachim: Did this help?

-------------------------------------------------------------------------------------------------------

Slf4j still needs to deal with the housekeeping of its BOM (best integrate it into the build process) - which is essentially what other companys/teams gain from having a single BOM for a library - less housekeeping. It would simply make an awesome library just a little bit more awesome ;)

> Please create a {{slf4j-bom}} POM which can be imported via dependency management. This makes consumer POM less verbose, no need to repeat version. The Spring Framework does this for example.
