The excludes should be relative to the share name. If you share name is
/home, then the exclude should be 'felfert/.m2/repository', not '/home/
felfert/.m2/repository'.
Your manual example works because you used "/home" instead of "/home/".
The more equivalent command for BackupPC is:
rsync -av --exclude=felfert/.m2/repository target:/home/ .
