From user:

It would be nice to see the functionality to build based on code or baseline change planned for a future release as well. I really like the baseline build functionality that's already there, but the latest code trigger doesn't really seem complete without also building if a baseline changes, or at least any non-modifiable component baseline (i.e., component dependencies). Most of our projects have a modifiable source component and one or more non-modifiable dependency components in the stream's configuration. When these dependencies change, we modify the stream configuration to use a new baseline of the dependency. If we were managing these dependencies with something like Maven, we'd update the project's POM instead which would trigger a build based on latest code. It seems odd that this behavior should be different based solely on how we manage dependencies (in the SCM tool or in the project metadata that happens to reside in the source (POM)).
