In case there is a @see tag provided for a parameter in the description,

in case there is a pseudo annotation '@see' found in a step docu the docu is retrived from
the parameter with the same name in the other step. Format is:
'@see <OTHER_STEP_NAME>'
This simplifies documentation for parameters with same name and same
semantics used in more than one step.
we do not have only groovy script, but also java files inside src folder.
Hence we should rely on the target/classes folder in order to see also the
compiled java classes, and not only the groovy scripts.
