Maven SCM plugin and relative paths

My directory structure looks somewhat like this:

.git
src
- parent
  - pom.xml
- submodule
  - pom.xml
  - addme.product

My pom looks like this:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

When I run mvn release:prepare, I get an error saying that

[ERROR] fatal: pathspec 'src\parent\src\submodule\addme.product' did not match any files

So, the plugin finds the files it should add, but when creating the command line doesn't respect the correct root directory. How do I fix this, without changing the location of the parent pom?

I ran into a similar problem (my root POM had a parent configuration POM, which was located in a subfolder). I was only able to solve this by creating a "proper" POM and folder hierarchy, meaning:

Root POM should be located in the project root folder
Submodlues should be subfolders of the project root folder and the folder structure should be reflected in the of the POMs
Source folders should be individual subfolders of the modules
