    Configure GIT_DIR by searching up the file system.
    Starts from the current working directory of the JVM and scans up through the directory tree until a Git repository is found. Success can be determined by checking for getGitDir() != null.

    Returns:
    
    this
    
    Throws:
    
    IllegalArgumentException - insufficient parameters were set, or some parameters are incompatible with one another.

    If an option was not set, the build method will try to default the option based on other options. If insufficient information is available, an exception is thrown to the caller.
    
    Returns:
    
    a repository matching this configuration. The caller is responsible to close the repository instance when it is no longer needed.
    
    Throws:

    Throws:
    
    IOException - the repository configuration could not be read.
  - setupInternals
```
protected void setupInternals()
                       throws IOException

    the repository's configuration.
    
    Throws:
    
    IOException - the configuration is not available.
