BeanUtils\.copyProperties\s*\(\s*([\w\_]+)\s*\,\s*([\w\_]+)\s*\)\s*\;

Wherever a space can be found when writing code, match it with 0 or more spaces. That by using \s* Could use [ ]* but \s might be sufficient in this case.

Then add captures for the source and destination by adding them in brackets. Or use [\w\_]+ to match other variable names. With a + to mean at least 1 char. NB: if your variable have any other non-alphanumeric chars, add them to the [...] list.
