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

buildscript {
    repositories {
        jcenter()
    }
}

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'
