[SCM-920] Maven SCM plugin issue with flat multi module relative paths

Hi,

I am trying to apply the [Tycho Release Workflow](https://wiki.eclipse.org/Tycho/Release_Workflow) and everything goes well as long as i use a tree structure for the project. As soon as I try to use a flat multi module structure the release fails because of the Maven SCM plugin can not find the files.

Original configuration of the maven-scm-plugin as defined in the workflow is:

```java

        
            **/META-INF/MANIFEST.MF,
            **/feature.xml,
            */.product,
            **/category.xml
       
        */target/*
        Changing the Eclipse files versions

```

 

The structure is as follows:
   build -> pom.xml (parent pom)
   module1 -> pom.xml
   module2 -> pom.xml

 

First attempt to fix the issue was to use relative paths to the include section so I try the follwoing:

 

```java

    
         ../module1/META-INF/MANIFEST.MF,
         ../module2/feature.xml,
         ../module4/*.product,
         ../module3/category.xml
   
    */target/*
    Changing the Eclipse files versions

```

  maven-scm-plugin still could not find the files.

 

Second attempt was to change the basedir instead:

  

```java

${basedir}/..
        
            **/META-INF/MANIFEST.MF,
            **/feature.xml,
            */.product,
            **/category.xml
       
        */target/*
        Changing the Eclipse files versions

```

 

This got me an step further because the files where found by the plugin the problem was that maven-scm-plugin was adding the build folder incorrectly in front of the path of the files being added. This was the output:

```java
Executing: /bin/sh c cd '/srv/tools/jenkins/jobs/SSP(dev)/workspace/build/..' && 'git' 'add' '-' 'build/module3/category.xml' 'build/module2/feature.xml' 'build/module1/META-INF/MANIFEST.MF' 'build/module4/xyz.product'
```

  

After this I tried to also configured the workingDirectory but it only made it worst.

Reproduce the failure with the attached flat-tycho-project-master.zip and its parent and module pom.xml files. Start by tracing Maven SCM's basedir and path handling around the git add invocation shown in the report. Done means a flat multi-module layout finds the files and passes repository-relative paths to git without the extra build directory.
