React native android debug build tries to load env variables in release section of build.gradle

[uchar]

Description

This gradle config(android/app/build.gradle)

android {
    ndkVersion rootProject.ext.ndkVersion
    buildToolsVersion rootProject.ext.buildToolsVersion
    compileSdk rootProject.ext.compileSdkVersion

    namespace "com.xxx.yyy"
    defaultConfig {
        applicationId "com.xxx.yyy"
        minSdkVersion rootProject.ext.minSdkVersion
        targetSdkVersion rootProject.ext.targetSdkVersion
        versionCode 1
        versionName "1.0"
    }
    signingConfigs {
        debug {
            storeFile file('debug.keystore')
            storePassword 'android'
            keyAlias 'androiddebugkey'
            keyPassword 'android'
        }
         release {
            storeFile file(System.getenv("MYAPP_UPLOAD_STORE_FILE") ?: MYAPP_UPLOAD_STORE_FILE)
            storePassword System.getenv("MYAPP_UPLOAD_STORE_PASSWORD") ?: MYAPP_UPLOAD_STORE_PASSWORD
            keyAlias System.getenv("MYAPP_UPLOAD_KEY_ALIAS") ?: MYAPP_UPLOAD_KEY_ALIAS
            keyPassword System.getenv("MYAPP_UPLOAD_KEY_PASSWORD") ?: MYAPP_UPLOAD_KEY_PASSWORD
        }
    }
    buildTypes {
        debug {
            signingConfig signingConfigs.debug
        }
        release {
            signingConfig signingConfigs.release
            minifyEnabled false
            proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
        }
    }
}

with react-native run-android generate this error

But it should works fine because I'm using debug build and dont want to set my release env variables during debug builds ( it works fine on release builds if I set them )

Steps to reproduce

1_ Create empty project
2_ Add above to build.grade
3_ Use npm run android and you should see the error
(You can also simply look at reproducer output https://github.com/uchar/react-native-build-bug/actions/runs/12184080305/job/33987094131 )

This is an Android question and is not necessarily related to React Native.

The problem you're having is that the build.gradle file is all "executed" for both debug and release variants, even if you're attempting to build only one of the two.

I suggest you change your code to something like:

         release {
            if (System.getenv("MYAPP_UPLOAD_STORE_FILE") != null) {
	            storeFile file(System.getenv("MYAPP_UPLOAD_STORE_FILE"))
			}
			// ...
        }
