Anthony Whitford commented on MSCMPUB-4:
----------------------------------------
For the *Maven Multi Module Configuration* advice, it mentions this command:
{noformat}
mvn -Preporting site site:stage
{noformat}
Is the {{reporting}} profile necessary? (Because it doesn't seem to exist.)
I am able to stage the site just fine, but the next step:
{noformat}
mvn scm-publish:publish-scm
{noformat}
is failing for me with:
{noformat}
[ERROR] Failed to execute goal
org.apache.maven.plugins:maven-scm-publish-plugin:1.0-SNAPSHOT:publish-scm

org.apache.maven.plugins:maven-scm-publish-plugin:1.0-SNAPSHOT:
publish-scm failed: The scm url cannot be null. -> [Help 1]
{noformat}
The root issue seems to be here:
{noformat}
Caused by: java.lang.NullPointerException: The scm url cannot be null.

_Am I doing something wrong?_
