   @jslok Thanks for the detailed report and the proposed fix! 👍

   What I found: I searched the repository for android/build.gradle, buildCMake, afterEvaluate, libNitroModules, and externalNativeBuild. The android/build.gradle file is referenced in CONTRIBUTING.md (line 158) as the file that "triggers the native C++ build (via CMake/externalNativeBuild)", but the file itself is not accessible in the current codebase snapshot — so I cannot confirm or deny whether the afterEvaluate block is already present.

   The proposed fix looks reasonable for a Nitro Modules-based library:

   afterEvaluate {
       tasks.configureEach { task ->
           if (task.name.startsWith('buildCMake')) {
               def nitroProject = rootProject.findProject(':react-native-nitro-modules')
               if (nitroProject) {
                   def nitroTask = nitroProject.tasks.findByName(task.name)
                   if (nitroTask) {
                       task.dependsOn(nitroTask)
                   }
               }
           }
       }
   }

   This should be added to android/build.gradle in the library root.

   A few questions for the maintainers:

   1. Is android/build.gradle intentionally excluded from the repo (generated by Nitrogen)? If so, this fix may need to go into the Nitrogen template or a custom gradle script.
   2. Is this reproducible only with parallel Gradle builds (--parallel)? That would help confirm the ordering issue.
   3. Other Nitro modules in the user's project don't hit this — could there be something specific about how IAP's CMake target links against libNitroModules.so compared to other Nitro modules?

   Maintainers: please check android/build.gradle and confirm whether the afterEvaluate task dependency block is missing.

   Thanks for the report and the fix suggestion @jslok!

   This has been merged in #3165. The afterEvaluate block now ensures buildCMake* tasks depend on the corresponding react-native-nitro-modules tasks.

   We investigated the nitro-modules 0.35.0 upgrade — no CMake/Gradle build order changes were made upstream, so this was a pre-existing race condition that likely became more visible with the recent upgrade.

   Will be included in the next release.
