i checked https://stackoverflow.com/questions/49510176/android-studio-gradle-sync-failed-could-not-head-received-status-code-5 but it not working

[sandy105]

It seems Jcenter downloads are down, please check https://status.bintray.com

[mifi]

Jcenter is shutting down. Maybe they are trying to warn us to switch. See react-native-community/discussions-and-proposals#331

[TBaoNguyen]

Just run with offline mode. Turn off your connection, run-android and turn it on back.

[ydv0121]

[arwysyah]

Is it another way to replace Jcenter to MavenCentral manually since jcenter getting server error now , and since jCenter is shutting down and affect Android apps globally starting May

[ydv0121]

@arwysyah i think jCenter extended their support till 1st Feb 2022

[Rananjaya]

same issue here :(

[arwysyah]

@ydv0121

Ah i see ,only Rest Api and UI will be sunsetted on May

“To clarify, the JCenter repository will keep serving packages for 12 months until February 1st 2022. Only the JCenter REST API and UI will be sunsetted on May 1st 2021.”

[ydv0121]

JCenter is up now.

[khuongsatou]

it worked

[arwysyah]

you can close the issue

[gopidevarapalli]

Just run with offline mode. Turn off your connection, run-android and turn it on back.

Excellent. Thank you :) You have saved my time.

[Lexical-Luke]

I've just started having this issue today, I checked https://status.bintray.com and it seems jcenter and bintray have already been sunset even though the date was 1 Feb 2022. What can I do to fix this issue, besides for offline mode?

[arwysyah]

@Lexical-Luke you need to update your build.gradle

Remove or disable jcenter() and change it to mavenCentral() android/build.gradle
repositories {
mavenLocal()

// jcenter() // <- remove it
mavenCentral() // <- add it

maven { url "https://plugins.gradle.org/m2/" }
maven { url "https://repo.spring.io/plugins-release/" }

}

[Lexical-Luke]

@arwysyah, I've tried these but I still get the same issue.

Here is the android/build.gradle

allprojects {
    repositories {
        mavenLocal()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url("$rootDir/../node_modules/react-native/android")
        }
        maven {
            // Android JSC is installed from npm
            url("$rootDir/../node_modules/jsc-android/dist")
        }
        maven { 
            // react-native-date-picker
            url "https://www.jitpack.io" 
        }

        google()

        maven { url "https://plugins.gradle.org/m2/" }
        maven { url "https://repo.spring.io/plugins-release/" }
    }
}

[arwysyah]

Sorry bro ,currently i didnt open my Laptop ,
But here the things

maybe you should update your React Native version, currently 0.65 already replaced jcenter()

and here some references, hope can help you:

[Lexical-Luke]

@arwysyah, I made sure to take my time and check everything, I tried all 3 of your points independently then all together, even tried some other tricks like running $ npm ls metro-config and trying to resolve those issues, I'm still left with the same issue if not more of the same.

[latusdenis]

@Lexical-Luke Same for me. The issue persists for 2 days already and it seems like the server is down: https://isdown.app/integrations/bintray

[arwysyah]

@Lexical-Luke its looks like you already solved the problem ,
and i think better for you to change your credential account @latusdenis

[Lexical-Luke]

@arwysyah, Definitely not solved & those are @latusdenis's creds.

[arwysyah]

Hmm okay i see 🤔,
@Lexical-Luke @latusdenis

i found an article in OneSignal website

Its sounds reasonable that there are some libs maybe havent changed to mavenCentral() on your project .

I havent tried on my laptop

but if you want to try it

delete your modules and reinstall

And here is the complete article :
https://www.google.co.id/amp/s/onesignal.com/blog/android-migrate-jcenter-to-maven-central/amp/

[Lexical-Luke]

@arwysyah, I've done that literally hundreds of times, its the first thing I do before a clean install, also ./gradlew clean.

[latusdenis]

I'm using https://github.com/wgltony/react-native-braintree-dropin-ui, so should the lib move to mavenCentral()?

[arwysyah]

@Lexical-Luke 😂😂, but how if you create a new project and trying to run it ? Is it running correctly ( react native latest version)? Sometimes its possible to get and error because of gradle because of network connection when sync the gradle , but for your case i think its not . 🤔

@latusdenis i think the libs already implemented mavenCentral () too . But i never used that lib, so really sorry for that.

I am searching by phone cause i am on leave 😂🙏🏻

[Lexical-Luke]

@arwysyah, our dev team has other apps, this is the only one affected, the others are on RN 0.64.0. This one, that is having issues, was on RN 0.63.4, I've since upgraded it to 0.65.0.

Interestingly enough those apps still reference jcenter() in the build.gradle.

[Lexical-Luke]

I'm still getting this error:

      > Failed to list versions for com.facebook.react:react-native.
         > Unable to load Maven meta-data from https://google.bintray.com/flexbox-layout/com/facebook/react/react-native/maven-metadata.xml.

Any help would be appreciated.

[arwysyah]

@Lexical-Luke i just tried to look into detail your problem ,flexbox-layout releases appear to only be published to jcenter and are not present on maven central.
Remove

maven {
url "https://google.bintray.com/flexbox-layout"
}// remove this one if exist

Try this :

dependencies {
implementation 'com.google.android.flexbox:flexbox:3.0.0'
} //add this one

For detail information:

google/flexbox-layout#566 (comment)

@latusdenis i dont know if you already solved the problem or not, i guess you issue also because
https://cardinalcommerceprod.jfrog.io/ ,

i found this article https://cardinaldocs.atlassian.net/wiki/spaces/CMSDK/pages/1998914459/Setting+up+CardinalMobileSDK+-+Android+-+V+2.2.5
Idont know it would help you or not, i cause i never used the lib and sdk

if bug still appear :maybe we can open the issue

[Lexical-Luke]

@arwysyah, thanks for the leads, unfortunately, I've already tried them out - same error.

I can't test that second article relating to jfrog as there doesn't seem to be an option to create an account.

[arwysyah]

@Lexical-Luke How if you change your internet connection, sometimes its also possible to happened because of your network connection didnt have a proxy 🤔
google/flexbox-layout#566 (comment) (Kotlin)

[Lexical-Luke]

@arwysyah, unfortunately, I don't have a VPN to try out some net config, I tried connecting through my phone's wifi, and still no luck, my colleague has the same issue and we both work from home (different networks).

Here is my current build.gradle, I am currently using kotlinVersion = "1.4.32", I'm not sure if additional steps are required.

buildscript {
    ext {
        buildToolsVersion = "31.0.0"
        minSdkVersion = 21 
	kotlinVersion = "1.4.32"

        targetSdkVersion = 31
        ndkVersion = "21.4.7075529"
        RNNKotlinVersion = kotlinVersion
    }
    repositories {
        google()
        mavenCentral()
        mavenLocal()
        // jcenter()
    }
    dependencies {

        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        mavenCentral()
        mavenLocal()
        // jcenter()

        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url("$rootDir/../node_modules/react-native/android")
        }

        }
        maven { url "https://maven.google.com" }        
    }
}

[arwysyah]

Have you tried this one :

There is no flexbox on Maven Central. There is a flexbox on Google's Maven repo, but only 3.0.0. Some transitive dependency of yours is seeking 2.0.1. And, based on that dependency list, it must be io.kommunicate.sdk:kommunicateui:2.1.8 that is looking for the older flexbox.

Unfortunately, the developers of io.kommunicate.sdk:kommunicateui have not updated their library, apparently.

You can try manually adding your own dependency on com.google.android.flexbox:flexbox:3.0.0 and perhaps setting up an exclude rule on the io.kommunicate.sdk:kommunicateui:2.1.8 dependency to tell Gradle to ignore its transitive dependency on flexbox. Ideally, the developers of io.kommunicate.sdk:kommunicateui would update their library to depend on com.google.android.flexbox:flexbox:3.0.0.

To exclude the failing dependency, change:

implementation 'io.kommunicate.sdk:kommunicateui:2.1.8'
to:

implementation('io.kommunicate.sdk:kommunicateui:2.1.8') {
exclude group: "com.google.android", module: "flexbox"
}

😆😆

[Lexical-Luke]

@arwysyah, you may be on the right track we are using kommunicate and it has been a problem child in the past 🥴

We have this in the app/build.gradle:
implementation project(':react-native-kommunicate-chat')

I changed it to your suggestion and the only thing that has changed is the build time fails twice as fast 😂 - same error.

[arwysyah]

@Lexical-Luke I saw they module/libs , its looks like they havent changed the version of flexbox ,still from old version, i was wondering have you tried to changed from their libs that exist on your project ? I saw also on Zendesk they have a same issue before , but i dont know 😂😂,since my suggestion always got failed 😂.

here the pict from the libs/module :

@Lexical-Luke

implementation 'com.google.android.flexbox:flexbox:3.0.0' Using this instead of maven {url "https://google.bintray.com/flexbox-layout"}
inside your project and their libs(kommunicate-react-native-sdk)
Like this : #31165 (comment)
did you changed the firebase version ?
How about using “com.google.gms:google-services:4.3.10” ?

[Lexical-Luke]

@arwysyah, I'm not sure about the firebase version. I tried “com.google.gms:google-services:4.3.10” it doesn't change the result.

I tried removing Firebase version: implementation platform('com.google.firebase:firebase-bom:29.0.0') and made it implementation platform('com.google.firebase:firebase-bom') then I got the original error:

@Lexical-Luke

. I think no need to remove firebase.bom version , cause this “ implementation platform('com.google.firebase:firebase-bom:29.0.0')” the correct version that exist on firebas doc ,

hmm 🤔🤔 weird , i checked the flexbox already on maven also
Here : https://maven.google.com/web/m_index.html?q=Flex#com.google.android.flexbox:flexbox:3.0.0

[Lexical-Luke]

@arwysyah, can we open up the issue again? So far I've gone full circle down that rabbit hole. I read through each of the 126 comments in issuetracker tried out a bunch of things and even tried upgrading Gradle and a few dependencies, I've now got the same issue I started with...

[arwysyah]

@Lexical-Luke yeah we can reopen this issue , and also better for you to investigate your 3rd party libs since your upgraded the project version or create a new issue i guess and mentioned this issue because its still related i guess 😂.

[Lexical-Luke]

@arwysyah, we're currently in the process, opened a ticket with kommunicate and we are checking all our packages, have to try everything to get our app to build again 😅

[gopidevarapalli]

I am able to resolve it. Update the packages to latest version whatever package you are receiving 502.

[Lexical-Luke]

@gopidevarapalli and this error?

Hi Lexical-Luke,
Remove maven { url('https://cardinalcommerce.bintray.com/maven') } from build.gradle and try

[swatiredhu17]

I am facing similar issue:

[Lexical-Luke]

Update on my previous issue: We were unable to fix/patch the previous issue and we decided to just start a massive cleanup, we got rid of loads of packages, even removed Intercom entirely and moved to gifted chat. Good luck.

Try to remove maven { url('https://dl.bintray.com/maven') } from build.gradle and check

[arwysyah]

I guess mostly your problem its because you are using intercom package

Try this :
In the build.gradle file, it uses the following dependency under repositories:

maven {
url 'https://dl.bintray.com/intercom/intercom-maven'
}

[swatiredhu17]

UPDATE HERE!!

Yes, it worked.
As below code was in node_modules, i can't delete that directly. After checking library(https://github.com/tinycreative/react-native-intercom) for updates, it was recently fixed. Code was removed in upgraded version.

Code that was causing issue:
maven {
url 'https://dl.bintray.com/intercom/intercom-maven'
}

[arwysyah]

Yeah so, i think the problem are not about react native core, so checking the libs that you are using inside your React Native App. Since also react native contributor keep updating and improving react native for better performance and experience.

note : currently you can using JSI and bridge C/C++ for better performance maybe its a bit hard for now but later it will easier since JSI havent completed yet currently
