mavenCentral() is not working instead jcenter()

Question

mavenCentral() is not working instead jcenter(). When I use mavenCentral() I am getting below error message,

Could not HEAD 'https://google.bintray.com/flexbox-layout/com/google/android/flexbox/2.0.1/flexbox-2.0.1.pom'. Received status code 403 from server: Forbidden
Disable Gradle 'offline mode' and sync project

With jcenter() above error is not coming.

Can I use jcenter() in my project even after jcenter() is deprecated. What is the last date of jcenter() to be use in our project.

Can you post your build.gradle please? – Corrientes

@Skizo-ozᴉʞS I added app build.gradle. Please see. – Anthill

could you remain the jcenter() ? There are still some apis that needs that. Keep both. – Corrientes

Also add your build.gradle of your project please, not of app – Corrientes

I use implementation("com.github.google:flexbox-layout:2.0.1") for flexbox after removal of jcenter in the project – Grettagreuze

@Grettagreuze I used implementation("com.github.google:flexbox-layout:2.0.1") but still getting the same error. – Anthill

Answer 1

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"
}

I added implementation 'com.google.android.flexbox:flexbox:3.0.0' but getting same error. – Anthill

@AmitYadav: Then you probably also need to exclude the failing dependency -- I updated my answer to show the syntax for that. – Trolly

I excluded implementation('io.kommunicate.sdk:kommunicateui:2.1.8') { exclude group: "com.google.android", module: "flexbox" } and its working – Anthill

Answer 2

The problem is in the FlexBox Layout library

https://google.bintray.com/flexbox-layout/com/google/android/flexbox/2.0.1/flexbox-2.0.1.pom

You get 403 forbidden for any reason. There's a mavenCentral() artifact using the flexbox 3.0.0 in case you could use that one.

https://maven.google.com/web/index.html?q=flexbox#com.google.android.flexbox:flexbox:3.0.0

You should add this dependency (or add exclude rule in your io.kommunicate.sdk:kommunicateui:2.1.8 or the one that is using flexbox)

dependencies {
    ....
    implementation 'com.google.android.flexbox:flexbox:3.0.0'
    ....
}

I added implementation 'com.google.android.flexbox:flexbox:3.0.0' but getting same error. – Anthill

Have you put the exclude in your library where you use flexbox? Also have you tried the close the project and clear cache and restart? – Corrientes

I didn't exclude. Can you plz tell me how to do that. I cleared the cache but it's not working – Anthill
