Native<PackageName>Spec doesn't exist on Android

[CJxD]

Description

After building a fresh project, the Kotlin native module file tries to extend NativeSpec but it hasn't yet been built.

class TestModule(val reactContext: ReactApplicationContext?) : NativeTestSpec(reactContext) {
                                                               ^^^^^^^^^^^^^^

I expected to see something in android/generated/source/codegen but the directory doesn't exist.

I see that builder-bob has not been set up to build an .aar - is this necessary to make it work?

I tried to reconfigure with .aar files enabled. I had to upgrade the Android Gradle plugin to 7.3.0 to work with the version of Gradle in use (7.4) and change the androidBundleName option from android.aar to android-release.aar. After this, it still refuses the build with the same error - nothing seems to be generating this class even if I comment out the code to make npx bob build run all the way through.

The test example I've given should reproduce, but I have also copied in the repository in which I am struggling to get set up which is a fairly simple API.

What command are you running to build the project?

What command are you running to build the project?

That command creates the project. What command are you running to build the project?

[CJxD]

Sorry for the delay! I run yarn followed by yarn build.

[satya164]

The android project is built by running yarn example android - which will generate the codegen files, build the android code and run the app.

@sawa-ko could you create a new issue with a reproducible example? Could you post the full error message there?
