[Android] Can not test the example app in release mode

[ISnowFoxI]

Description

I have built a small library using nitro-modules but when I run yarn android --mode release command, the app doesn't build. It fails with the following error.

Type com.facebook.fbreact.specs.NativeAccessibilityInfoSpec is defined multiple times:

Commenting out the below code fixes it. The code is located in the build.gradle file of the library. I am curious whether this is important or not, if the example app has this already, why is it needed in the package file?

if (isNewArchitectureEnabled()) {
  apply plugin: "com.facebook.react"
}

I am going to rebuild the library so, I will delete the reproduction repo.

Hey @ISnowFoxI I was able to reproduce it locally so let's keep this issue open until we fix it. And thank you so much for the suggestion. Will take a look

[ISnowFoxI]

Hey @atlj, sure thing. But I've already deleted the repo, Would you mind creating a new reproduction repo?

Would you mind creating a new reproduction repo?

No worries, since I'm able to reproduce it, we don't need a repro again.

comment this in android/build.gradle is resolve the issue
