The <scm> tag is supposed to be defined in all pom.xml files that are a
release root, as the value of that tag is used to perform the checkout for
the release:perform build.

Depending on your SCM you may not need to define it for all your poms.

For example, if you use Subversion as a SCM, and your project is structured
such that the parent is in the parent directory then the calculated
inherited scm tag will match the effective scm tag.

On the other hand, if you use Git as a SCM then you will just need to put
the scm tag in the root pom of every git repo (because with Git, best
practice is to have the release root as the root pom)

My recommendation is just to always define the <scm> tag if the project is
a release root. This has the benefit of signalling to readers that the pom
is intended to be a release root.

FYI: by "release root" I mean the root project of a multi-module set of
projects that get released and versioned atomically. You only *need* the
scm tag in the release root poms (you may also want to add the scm tag to
child poms that do not share the inheritance hierarchy if you are using the
site plugin to generate documentation - as in those cases the computed scm
URL would be incorrect... but it is not required by the release plugin)
