<com.kofigyan.stateprogressbar.StateProgressBar/> sync issue 

i cannot sync this implementation:

implementation ‘com.kofigyan.stateprogressbar:stateprogressbar:1.0.0’ with my xml code

<com.kofigyan.stateprogressbar.StateProgressBar-->                      android:id="@+id/step_progress"
        android:layout_width="wrap_content"   
                     android:layout_height="wrap_content"
                       android:layout_marginTop="30dp"                                          app:spb_animateToCurrentProgressState="true"     
                 app:spb_checkStateCompleted="true"/>

what is the reason for this sync issue am already used the jcenter() and the MavenCenter() for this but i cannot sync with the project please provide the better approach and the latest implementation for this purpose
