'React-Native assembleRelease fails for task ':app:bundleReleaseJsAndAssets'

When I run ./gradlew assembleRelease build is failed with this error:

Error:Execution failed for task ':app:bundleReleaseJsAndAssets. 
> A problem occurred starting process 'command 'node'

I searched on the internet and found some topics about it, but I couldn't solve my problem.

React-Native version: 0.54.0

EDIT:
Now I'm running ./gradlew assembleRelease --info from the terminal instead of Android Studio and I get different error.
Here is the result:

It seems gradle is looking for libs folder in all modules, but there are no libs folders in the node modules. It's true, but I don't know why gradle is looking for libs folder.

Solution 1:^[1]

First:

react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res

finally build:

./gradlew assembleRelease -x bundleReleaseJsAndAssets

Solution 2:^[2]

Looks like you haven't made a js bundle so please make a bundle first by using command :-

 react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res

then in your project directory

 cd android

Clean your gradle

 ./gradlew clean

and make a build finally

./gradlew assembleDebug

Try this. Hope it will helps you.

Solution 3:^[3]

For me the creating the bundle failed, but I noticed this comment by Sahin Elidemir:

just ./gradlew assembleRelease -x bundleReleaseJsAndAssets saved me.

It almost worked for me. What worked at the end was (notice the app:, which for me it fails without, and a clean for good measure):

./gradlew clean app:assembleRelease -x bundleReleaseJsAndAssets

Solution 4:^[4]

Just using ./gradlew --stop and then ./gradlew assembleRelease worked for me.

Solution 5:^[5]

I had the same problem, the solution was :

cd to yourApp/android folder

run this

./gradlew --stop

and then

./gradlew assembleRelease

This gonna build your app.

After build is done, go to see your application(apk).

android\app\build\outputs\apk\release

Solution 6:^[6]

This is working for me, Please follow the below steps:-

1) Stop Running Gradle

 $ cd RectNatoveProjectName & cd android  (Open your project and go to android folder)  
 $ ./gradlew --stop (Run this command to stop old running Gradle service )

2) Update the android app build gradle

project.ext.react = [
        nodeExecutableAndArgs : ["/usr/local/bin/node"]
];

3) Get Node details

$ which node

> (Result will be like "/usr/username/.nvm/versions/node/v10.7.0/bin/node")

4) Link node (very imp step copy the above result in step 3)

- ln -s /usr/username/.nvm/versions/node/v10.7.0/bin/node /usr/local/bin/node

5) If Step - 4 return file exist - then to go the folder /usr/local/bin/ and delete the "node" file and perform the step -4 again.

6) If Step - 4 run successfully then this node issue will be resolved.

I now this is late. may be this will help somebody.

For me it i had to upgrade to latest react-native-sentry.

apply from: "../../node_modules/react-native-sentry/sentry.gradle"

was causing problem

Solution 8:^[8]

The steps above really helped.

Here's the scripts that work for us with react-native 0.55.3.

Run the android-build command locally or CI to generate an APK.

        }

        var result = data.replace(/                \/\/ Set up inputs and outputs so gradle can cache the result/g, dataFix);

I did it like this and it works:

Removed node modules (you can do it by running this command rm -rf node_modules)
Run npm installl or yarn install
Then run ./gradlew clean && ./gradlew app:assembleRelease or ./gradlew app:assembleDebug

Solution 10:^[10]

I was using the wrong image size (i.e [email protected]) which caused me this problem. When I deleted that [email protected] file...it worked!!

Solution 11:^[11]

As of RN 0.58, for CI builds the commands is as follows:

First create directories:

mkdir -p app/build/generated/assets/react/production/release/ && mkdir -p app/build/generated/res/react/production/release

node ../node_modules/react-native/local-cli/cli.js bundle --platform android --dev false --entry-file index.android.js --bundle-output app/build/generated/assets/react/production/release/index.android.bundle --assets-dest app/build/generated/res/react/production/release --max-workers 1 --reset-cache

Also you may also want to add for your production builds according to this;

--minify true

Taken from RN's source

NOTE: We added --max-workers 1 not to deplete CI resources since they are limited to lower numbers (mem&cpu).

Consider checking all your JS (React native). I faced this issue coz have a coding error in the JS file (React native).

Solution 13:^[13]

For me:

OS: Windows.
I just copied the .keystore file to android\app.
cd android && gradlew --stop then gradlew assembleRelease.

Solution 14:^[14]

if you are running these commands in VS code, Just open the project in cmd (administrator mode) in android folder run $ gradlew clean $ gradlew assembleRelease

Solution 15:^[15]

if you are using macOS and using react native try this:

brew install react-native-cli
./gradlew --stop
./gradlew clean
./gradlew aRor ./gradlew assembleRelease

Solution 16:^[16]

I had the same problem. In my case, after a few hours, I saw this on GitHub: https://github.com/getsentry/sentry-react-native/issues/578#issuecomment-503428032. I had renamed the project on Sentry. If you renamed the project on, update the android/sentry.properties and ios/sentry.properties file.

defaults.url=https://sentry.io/
defaults.org=yourorg
defaults.project=newprojectname
auth.token=?

And that's it
