Update all relevant starter POMs to include a `spring-core` dependency
with an exclusion on `commons-logging`. This prevents `commons-logging`
and `jcl-over-slf4j` from both being on the classpath.
Also add enforcer rules to ensure that commons-logging doesn't sneak
back in, and that there is no dependency convergence. (some additional
libraries were required in spring-boot-dependencies)
Tested with a sample maven project as well as using the `spring jar`
command.
Fixes gh-985
This commit harmonizes the dependency management of internal modules
so that versions can be omitted everywhere. Update the maven coordinates
to provide the full groupId for consistency
Add dependencies that are usually picked up transitively directly to
spring-boot-starter-web. Helps mavens dependency conflict resolution
algorithm to pick the correct version.
