Run gradlew always fails "Error: Unable to resolve module"

natalius_dev · September 15, 2023, 10:00am

Every other phase of the build runs flawlessly but it always fails at Task :app:createBundleReleaseJsAndAssets even though my javascript bundles just fine and it doesn’t explicitly state that it failed.

Here is a repository with the source code: https://github.com/Natalius-dev/temp_expo_post

Here is a link to the build page if any expo employees see this: https://expo.dev/accounts/natalius_dev/projects/cc-cup-2023/builds/86000446-8803-4f29-831e-d0af42221027

Hi @natalius_dev

I cloned your test repository and tried building it. It seems the repository is missing a couple of dependencies. After I installed react-native-tab-view and react-native-pager-view it built fine for me.

One difference between a newly-created app and your app is as follows:

This suggests to me that you have run npx expo prebuild or npx expo run:android which would have generated an android directory. It’s possible this is now out of sync.

If you do in fact have an android directory, but you have not made any manual changes under that, then I recommend you just delete it (and ios).

Another thing you can do is add android and ios to .gitignore so that they will not be uploaded to the EAS Build servers.

If you did make manual changes under android or ios, then I suggest you run npx expo prebuild --clean and redo those manual changes.

Hi @wodin

Thank you for your reply but I still seem to be getting the exact same error messages after making the appropriate changed. Could you please make a pull request to the repository so I can try it again. Also what profile did you build with?

I’ve also found out that builds with "developmentClient": true seem to work for me

wodin · September 16, 2023, 5:34am

Could you elaborate on exactly what you changed before trying to build again?

I built with the preview profile.

I’ve created a PR. Try cloning it again and see if it builds

natalius_dev · September 16, 2023, 6:19am

@wodin I tried building after trying your version and it didn’t work on this account but it built perfectly fine on a new expo account. For now I’ll just use this new account to build my project. Thank you so much for the help!

wodin · September 16, 2023, 7:55am

It should not have anything to do with the account. The only possible way that comes to mind (but I don’t know if this is really possible) is if maybe you have some Expo secrets that the code makes use of in some way.

Did you try the following using the original Expo account?

Change to a blank directory
Clone the repository
cd temp_expo_post
npm install
eas build -p android --profile preview

natalius_dev · September 17, 2023, 11:00am

Yeah that seems to be the root of the problem. My original folder was inside another project which already had a git repository

wodin · September 17, 2023, 1:18pm

OK. Not entirely sure why that would be a problem, but glad you got it figured out
