 Notice that before Maven 3.1.0, with logger created by Maven, some code used to pass logger from class to class because it could not create a new logger:

		cr.err = err
		return n, cr.err
	}

	cr.offset = copy(buf, cr.buffer)
	n += cr.offset
	return n, err
}

// readTrailers will read all trailers and populate cr.trailers with actual values.
func (cr *s3UnsignedChunkedReader) readTrailers() error {
	var valueBuffer bytes.Buffer
	// Read value
	for {
		v, err := cr.reader.ReadByte()
		if err != nil {
			if err == io.EOF {

to get the MojoDescriptor for the goal that needs to be run. In the MojoDescriptor we are interested in the <configuration/> element and <parameters/> element. From these elements we need to make a component configuration for the MojoExecution. The actual DOM like structure we create is of type PlexusConfiguration and is the type we use with the ComponentConfigurator to initialize fields in a Plexus component. Typically this is done within Plexus with the configuration supplied with component configuration,...
