[Android] Using relative paths for ENTRY_FILE now end up in build failure

[DomiR]

Description

Before bb02ccf we were able to run ENTRY_FILE="./index.custom.js" npx react-native android --variant="release" but now I get:

* What went wrong:
A problem was found with the configuration of task ':app:createBundleConnectdevReleaseJsAndAssets' (type 'BundleHermesCTask').
  - In plugin 'com.facebook.react' type 'com.facebook.react.tasks.BundleHermesCTask' property 'entryFile' specifies file '$HOME/rn-project/android/app/index.custom.js' which doesn't exist.

It seems that the entry file is now resolved relative to the android root project. Not sure if this was intended.

Version

0.71.3

Steps to reproduce

Build release variant while passing in relative path for ENTRY_FILE.

Snack, code example, screenshot, or link to a repository

* What went wrong:
A problem was found with the configuration of task ':app:createBundleConnectdevReleaseJsAndAssets' (type 'BundleHermesCTask').
  - In plugin 'com.facebook.react' type 'com.facebook.react.tasks.BundleHermesCTask' property 'entryFile' specifies file '$HOME/rn-project/android/app/index.custom.js' which doesn't exist.

property 'entryFile' specifies file '$HOME/rn-project/android/app/index.custom.js' which doesn't exist.

Does the file '$HOME/rn-project/android/app/index.custom.js' exists?

[DomiR]

It is exists in the root folder, which is were react-native init puts index.js: '$HOME/rn-project/index.custom.js'

Now it expects the path of the entry file to be relative to the android root: '$HOME/rn-project/android/app' which was not the case before. I guess ENTRY_FILE="../../index.custom.js" npx react-native android --variant="release" would work but it's not consistent with iOS.

@cortinico Thank you very much for looking into this! Cheers 🍻

A similar error shows in react-native 0.71.11 ("specifies file '$HOME/PROJECT/android/app/index.js' which doesn't exist."),
while > Task :app:createBundleDevelopmentJsAndAssets,
when run ./gradlew clean assembleDevelopmentin android/.
I set entryFile paths already ("src/index.tsx").
Is there any new way? @cortinico

I was able to solve this error by setting the entryFile path inside android/app/build.gradle
Navigating from the actual file: entryFile = file("../../index.tsx"), knowing that my index.tsx is located in the root of my project. So make sure you're going back to the root from your current location then to your src folder.

in my case i had to add entry in the android/app/build.gradle.kts react block:

react {
  entryFile = file("../../index.tsx")
}

but I've got more android modules in my project so for others path may be entryFile = file("../index.tsx")

change index.ts or index.tsx to index.js
