I have encountered exactly this problem and realised that, though this
is solvable, it is better (if possible) to build the arrays
differently in the first place. I realise this may not be possible
for you but if you change the original conditions building so that it
builds two arrays of the form
conditions = ["(modulable_type=?)","(parent_id=?)"]
and
values = ["Task","2"] and so on, so just adding each condition and
value as they arise, then the required result is
c = [conditions.join(" AND ")] + values
No doubt there are even better ways, and it may not match your needs
anyway, but for me it worked well as I was working through a number of
options building the conditions as I went.

and b similarly
Then c = (a+b).collect(
