Could someone let us know what could be the cause of this issue and the possible solution?


Same issue here, will update if I find a workaround. It seems jcenter just removed all their .jar files?

Thank you for your reply
Is there any reason for which ionic uses recyclerview and can that be avoided? Alternatively is there another option to recyclerview?


I simply wrote a pre build hook to swap the ordering of maven and jcenter in the gradle files.

can you let me know how i can do this too? i haven’t done this before please can you share your code with me.


I have the same issue.
A few days ago it was ok

You need jcenter below maven in build.gradle.
example for you

allprojects {
    repositories {

        maven {
            url ""

I hope this will help

Thank you i have also done that changes i got that solution from the below link
