unresolved reference BuildConfig

Question

When i'm try to rebuild my project i get the error below:

warning: flag is not supported by this version of the compiler: -Xallow-no-source-files
warning: flag is not supported by this version of the compiler: -Xjava-source-roots=/Users/tyln/AndroidStudioProjects/PhoneBox/base/navigation/build/generated/source/buildConfig/dev/debug
base/navigation/src/main/java/com/raqun/phonebox/navigation/IntentLoader.kt:7:9: error: unresolved reference: BuildConfig
        BuildConfig.PACKAGE_NAME,
        ^

> Task :base:navigation:compileDevDebugKotlin FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':base:navigation:compileDevDebugKotlin'.
> Compilation error. See log for more details

When I check the class there're no unresolved references.

I'm using Gradle Version 3.3.1

I almost tried everything such as Invalidate Cache / Restart, Clean and Rebuild, Close and Reopen project, Reimport project, delete idea folder etc but none of them worked.

Thanks for your help.

It's probably because you have not made a build since adding the field, BuildConfig and other variables/properties declared in a Gradle file will only be available AFTER a successful build. The following instructions will fix this:

Build -> Clean Project
Build -> Rebuild Project (comment any lines that cause compiler errors for now!)
Press Alt + Enter (Windows/Linux) or Option + Enter (macOS) on BuildConfig in your code and select Import... from suggested solutions.

Starting with android gradle plugin version 8, you now have to explicitly tell gradle that you want to generate the BuildConfig file.

android {

    //...
    buildFeatures {
        compose = true
        buildConfig = true // <- set this to true
    }
}

You just need to build your app by simply clicking on Build APK(s). Fasting way to fix it.

after I clean and rebuild the project still facing the issue.

for me it was a typo at gradle file :S, in your buildType check if there is a typo

buildTypes {

    deubg { <- it should be "debug"
        buildConfigField "String", "URL_BASE_DEBUG", '"https://example.example.com"'
        buildConfigField "String", "TOKEN_DEBUG", '"********"'
        buildConfigField "....."}


    release { 
        buildConfigField "String", "URL_BASE_PROD", '"https://example.example.com"'
        buildConfigField "String", "TOKEN_¨PROD", '"********"'
        buildConfigField "....."}

Like variant. Remove special characters like : or , from root project folder name or in any path to project

I don't know why even after cleaning, and invalidating caching or deleting entire ./gradle and ./idea folder won't help to fix this issue. I was using AGP and Gradle version 8.0.2 and 8.2.1 respectively, and now I am using AGP 7.4.2 and Gradle 7.6.2 and after doing Rebuild, I see BuildConfig got resolved.
