I am upgrading my website from CQ 5.5.1 to AEM 5.6 and the less parser is failing and it does not compile less files to CSS. Any suggestions of a possible fix to solve the issue.

Please provide as much information as possible about your problem, for example when the less parser fails, does it generate an error message? – gareththegeek Nov 20 '14 at 17:14

Are you using any maven-plugin to compile less files? – Saurabh Dec 02 '14 at 06:49

I came across this scenario recently where there was issue with less files not getting compiling adn was getting (uncompiled LESS src is included below) Rebuilding the clientlibs solved this issue and the error was gone and the styles where loading correctly.
Steps
Go to /libs/granite/ui/content/dumplibs.rebuild.html and invalidate the cache and rebuild the libs
Hope this will help

The thing is, in AEM 5.6.1 LESS compiler was updated to 1.3.3 and also the approach to server-side compilation was changed: prior to 5.6.1, your clientlib (including all embeds) was passed to LESS compiler as a single concatenated file.
Starting with 5.6.1, each LESS file in your clientlib is compiled separately, that is why the compilation will fail, in case you had your variable declarations in a separate file which was then embedded into numerous clientlibs. This leads to the following error (can be found in produced css):
/*****************************************************
LESS compilation failed due a JavaScript error!
Input: /etc/designs/widget.less
Error: @myVar is undefined
(uncompiled LESS src is included below)
*****************************************************/
To solve this issue, use @Import statement, which is now supported.
