Add BASE URL into Intelleji IDEA (I'm testing web site)

Could you hepl me, I'm new in IDEA :) How can I add into Gradle something like BASE_URL in Andoid studio, like this:

buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
            manifestPlaceholders.usesCleartextTraffic = false
            buildConfigField "String", "BASE_URL", '"https://someURL/"'
        }
    }

I copied it into my project, but it didn't work.
