Maybe better fill the variable like an array like this:
Code:
list="`find /a/technologies -name '*.jar' -print | grep \"Tuning/specificloader/lib\"`"

I added backticks in front and at the end of the command string so it will be substituted right there and assigned to the varaiable like a list.
You will have problems using it this way when you have blanks in file or directory names anyway.
I also added a -print since some versions of find might want it to print output in terms of portability.

Then when using it in the for-loop you just insert `$cmd` vs. $list.

Perl::Critic::Policy::BuiltinFunctions::ProhibitVoidMap(User Contributed Perl DocumentPerl::Critic::Policy::BuiltinFunctions::ProhibitVoidMap(3pm)

NAME

       Perl::Critic::Policy::BuiltinFunctions::ProhibitVoidMap - Don't use "map" in void contexts.

AFFILIATION

       This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

       "map" and "grep" are intended to be pure functions, not mutators.  If you want to iterate with side-effects, then you should use a proper
       "for" or "foreach" loop.

	   grep{ print frobulate($_) } @list;		#not ok
	   print map{ frobulate($_) } @list;		#ok

	   grep{ $_ = lc $_ } @list;			#not ok
	   for( @list ){ $_ = lc $_  }; 		#ok

	   map{ push @frobbed, frobulate($_) } @list;	#not ok
	   @frobbed = map { frobulate($_) } @list;	#ok

CONFIGURATION

       This Policy is not configurable except for the standard options.
