I'm getting an error when running the ./gradlew assembleRelease --stacktrace command in my React Native (v0.57.7) project's android folder:

When checking the folder android/build/generated/res/react/release/raw folder, the package.json file is being copied there along with all my other resources (mainly .json files).

What could I possibly do to prevent this weird thing from happening? Just to have said it, I've tried googling for hours now but can't find a solution.

    Don't import package.json inside your app. This will cause production build to include package.json into your bundle resources and it will cause Java error.

    Strange, I haven't seen that point in official React Native docs.

    Even more strange is we were successfully doing this in 57.8 but after upgrading to 60.0 got this error.

    Hmm, "package" is a reserved word in Java. Seems, RN Android build was including the package.json differently before the 60.0 version.

    Don't import package.json inside your app.

    Thanks this indeed fixed stuff for me. However I still need package.json to read version of the app and codeBundle. If you're like me then the only reason android is currently not working is that it has problem with package word. What I did is created short bash script to actually copy and rename package.json.:

    // Contents of file named: createVersion.sh
#!/bin/bash

rm -r version.json
cp package.json version.json

    Then inside my JS I do this: import packageJson from '../version.json'.
    Before you build your production apk just run sh ./createVersion.sh.
    It's definitely only a temporary solution but does the trick 👍 .

    For those of you that need to import package.json inside your app and want a fix that doesn't require changing any of your code, you can just add this script to the root project directory and run it postinstall:

    // fix_metro_android_release_bug.js
// Temporary fix for this issue: https://github.com/facebook/metro/pull/420
const fs = require('fs');

const fileLocation = './node_modules/metro/src/DeltaBundler/Serializers/getAssets.js';
const targetText = 'getJsOutput(module).type === \'js/module/asset\'';
const replacementText = 'getJsOutput(module).type === \'js/module/asset\' && path.relative(options.projectRoot, module.path) !== \'package.json\'';

const fileContent = fs.readFileSync(fileLocation, 'utf8');
if (fileContent.includes(targetText) && !fileContent.includes(replacementText)) {
  const patchedFileContent = fileContent.replace(targetText, replacementText);
  fs.writeFileSync(fileLocation, patchedFileContent, 'utf8');
}

    Then, inside your inside your package.json:

      "scripts": {
    "postinstall": "babel-node ./fix_metro_android_release_bug.js",
    ...
  }

    The script applies the changes from the PR which fixes the underlying issue (which hasn't been merged in yet).

    Another solution is to use the app.json that in many installations is already there (Expo, etc.).

    So, I put a new key there and import this json instead:

    {
  "name": "mobileapp",
  "displayName": "App",
  "customFields": {
    "jsBuildNumber": "1208"
  }
}
