react-native link get a wrong projectConfig (./android/src should be ./android/app/src)

Please provide all the information requested. Issues that do not follow this format are likely to stall.

Description

I was trying to use react-native-link <some package> but it returns an error

Error: ENOENT: no such file or directory, open 'D:\Android\Project\test\android\src\main\java\com\test\MainApplication.java' After I try to debug the problem and I log the projectConfig in registerNativeAndroidModule (from @react-native-community\cli-platform-android\build\link\registerNativeModule.js:36:27)

it shows

{ sourceDir: ‘D:\Android\Project\test\android’, isFlat: true, folder: ‘D:\Android\Project\test’, stringsPath: ‘D:\Android\Project\test\android\src\main\res\values\strings.xml’, manifestPath: ‘D:\Android\Project\test\android\app\src\main\AndroidManifest.xml’, buildGradlePath: ‘D:\Android\Project\test\android\build.gradle’, settingsGradlePath: ‘D:\Android\Project\test\android\settings.gradle’, assetsPath: ‘D:\Android\Project\test\android\src\main\assets’, mainFilePath: ‘D:\Android\Project\test\android\src\main\java\com\test\MainApplication.java’, packageName: ‘com.test’, packageFolder: ‘’, appName: ‘app’ }

which is wrong, those files should be under <root>\android\app\src\… instead of <root>\android\src\…

Expected Results

the projectConfig should be

{ sourceDir: ‘D:\Android\Project\test\android’, isFlat: true, folder: ‘D:\Android\Project\test’, stringsPath: ‘D:\Android\Project\test\android\app\src\main\res\values\strings.xml’, manifestPath: ‘D:\Android\Project\test\android\app\src\main\AndroidManifest.xml’, buildGradlePath: ‘D:\Android\Project\test\android\build.gradle’, settingsGradlePath: ‘D:\Android\Project\test\android\settings.gradle’, assetsPath: ‘D:\Android\Project\test\android\app\src\main\assets’, mainFilePath: ‘D:\Android\Project\test\android\app\src\main\java\com\test\MainApplication.java’, packageName: ‘com.test’, packageFolder: ‘’, appName: ‘app’ }

Quick fix: I solve the problem by manually changing the projectConfig.stringsPath and projectConfig.mainFilePath in registerNativeAndroidModule (from @react-native-community\cli-platform-android\build\link\registerNativeModule.js:36:27) projectConfig.stringsPath = 'D:\\Android\\Project\\test\\android\\app\\src\\main\\res\\values\\strings.xml'; projectConfig.mainFilePath = 'D:\\Android\\Project\\test\\android\\app\\src\\main\\java\\com\\test\\MainApplication.java';

It’s easier to provide a custom config to correct the paths to be used by the CLI.

I fixed it by adding a react-native.config.js file to my project with contents:

module.exports = {
    project: {
        android: {
            stringsPath: "app\\src\\main\\res\\values\\strings.xml",
            mainFilePath: "app\\src\\main\\java\\com\\swingle\\MainApplication.java"
        },
    },
};

Same issue on 0.64.1, I have to manually link this package. I don’t have MainApplication.java, I have MainApplication.kt, and it cannot find it.

I added this , but no success:

  "rnpm": {
    "android": {
      "mainFilePath": "src/main/java/one/realnote/app/MainApplication.kt"
    }
  },
