I am facing a problem while triying to extend classic theme(even if it s not recomended), but with the new Style book capabilities of liferay it's a good opportunity for us to speed up our theme creartion.
I have created a basic theme project using "yo liferay-theme" generator build my theme and deploy it, everythings OK. Then i downloaded the necessary files from lifery frontend-theme-classic github repo : [https://github.com/liferay/liferay-portal/tree/7.3.x/modules/apps/frontend-theme/frontend-theme-classic][1] [1]: https://github.com/liferay/liferay-portal/tree/7.3.x/modules/apps/frontend-theme/frontend-theme-classic i add the folders : css, images, templates and some necessary changes under the WEB-INF directory. When i run gulp build i got an error about undefined variables.
Here is the error message after a gulp:build :
Starting 'build:compile-lib-sass'... [23:21:28] 'build:compile-lib-sass' errored after 1.94 s [23:21:28] Error in plugin 'gulp-sass' Message: build_css\custom_properties_custom_properties_variables.scss Error: Undefined variable: "$btn-link". on line 10 of build/_css/custom_properties/_custom_properties_variables.scss from line 1 of build/_css/_custom_properties.scss from line 13 of build/_css/_custom.scss from line 21 of build/_css/main.scss
