Can GCC be used as a minification engine of CSS?
You can use GCC in AEM as well, see the documentation at .
 Change the minification engine for client libraries in AEM
GCC is primarily used for JS Minification and not CSS.
As stated in the official documentation:
We can investigate why the compression is failing, Please log a daycare ticket with the following info:
1) DEBUG logger for Clientlibs:
2) Share the above logger after you try to rebuild libraries from "http://<host>:<port>/libs/granite/ui/content/dumplibs.rebuild.html"
thanks for the reply.
Yes. but when i am trying to minimise the same css using online yui compression tool and i am able to minify and also i am facing this issue on publish env. so i guess it rules out a possiiblity of error in code.
Are you running into issues when using YUI for css?
