do you have this part in your build.gradle file? In the project level gradle file?

buildscript {
    repositories {
        jcenter()
    }
}

try unchecking the "offline work" gradle settings

jcenter is going away...

Yeah I have this in my project level gradle file

Have you got any solution ?

Have you tried specifying the version instead of using the + ?
It's possible the + is no longer aceeptable.

This worked for me.

implementation 'dev.dworks.libs:volleyplus:0.1.4'

Hi,
I am having the same issue. Not able to resolve.

Here is how I resolved it:

implementation 'com.github.DWorkS:VolleyPlus:master-SNAPSHOT'

If you have similar issue with other libraries, it's because jcenter has closed, so you need to check jitpack repository for example (or any other repo), copy the library github link and see what tags are available to you

Hi @Herz3h ,
This seems to have resolved the issue. Also, jitpack has a lot more working implementations. Thanks a lot!
