Failing Gradle build in Expo 49 project

[lpatino10]

It's brand new, but Expo 49 released the other day and I tried upgrading my project to it. The project itself is pretty simple but does have a working Heap installation for both Android and iOS.

After upgrading, iOS is still working fine, but I ran into a problem trying to create a new development build for Android. I'm using version 0.22.3 of this library. These are the relevant log lines in the failing "Run gradlew" step:

same issue here!

[stephanrotolante]

only suggestion, use a lower version of gradle. 8.x.x isnt working for me, but 7.6 is

[lpatino10]

@stephanrotolante can I ask how you're downgrading your Gradle version in your app? I've never messed with native configs and the internet isn't giving me a lot right now. Is it something with this Expo package?

[stephanrotolante]

@lpatino10 Just think about what gradle does, its a build tool that runs on the JVM that helps with managing build flows in projects. Its not specific to building Android apps. Think of it like Make

I think the 8x.x version of gradle changed their api enough to break the building of some libraries

Look at the gradle-wrapper.properties to see the gradle version configured for the project. Sync your Android project once when your ready to rebuild

[lpatino10]

Thanks @stephanrotolante! Finally got around to doing that and I can confirm that things work fine with the downgrade. The only hiccup I had was trying to do it in a managed project, but it is possible.

This issue stems from both Expo and React Native both trying to include the Heap native module when using npx expo install @heap/react-native-heap. This causes the Gradle tasks from one include to be dependent on the Gradle tasks in the second include of the same project. You can see this in the logs you shared where a task from :heap_react-native-heap is depending on an output from a task in :heap-react-native-heap. Notice that one has an underscore and one does not. This was a warning in Gradle 7, but it's an error now in Gradle 8.

The solution here is to exclude Heap from autolinking with Expo. This will cause the module to only be included one time (by React Native, not Expo) and the task tree to be clean and only contain explicit dependencies. You can do this by adding the following to your package.json file:

  "expo": {
    "autolinking": {
      "exclude": ["@heap/react-native-heap"]
    }
  }

Let me know if this works and we'll update the docs and close out the issue.

Hey @MCeley, thanks for the reply. I just got around to testing this and can confirm I was able to build for both iOS and Android successfully while still sending events to Heap. It's definitely nicer than pinning Gradle to v7.

Thanks again!
