Without knowing what "doesn't work" means and without any experience of the modules in question, the expression  'build-2/\$file[1]' is certainly suspicious. This is, of course, a non-interpolating string. Do you really intend there to be a literal backslash followed by literal  '$file[1]' in the final string?

c:\@Work\Perl>perl -wMstrict -le
"my @file = ('foo', 'bar', 'baz');
 my $s = 'build-2/\$file[1]';
 print qq{'$s'};
"
'build-2/\$file[1]'
