Configure LESS compiler in IntelliJ IDEA Ultimate

Question

These are my settings. Here is the error i am facing while compiling .less file.

Answer 1

You are incorrectly looking in Project Strucutre.

The Project Settings is the icon to the left (spanner).

Answer 2

Step 1: Install npm less module

npm install -g less

Step 2: Install the less plugins in Intellij Idea

File > Settings > Plugins

Step 3: Setup Less Profile

File > Settings > LESS Profiles

It'll auto-generate the CSS file as soon as any change is noticed in LESS if "Compile Automatically on Save" is used.
