Ivy can't resolve vaadin-testbench

Hey folks,
I try to get vaadin-testbench 5.0.0 with help of ivy.
When I declare following:

        <ibiblio name="vaadin-addons" usepoms="true" m2compatible="true"
            root="http://maven.vaadin.com/vaadin-addons" />

And

Ivy ends up in an error telling me: unresolved dependency: com.vaadin#vaadin-testbench-api;8.0.0.beta2: not found

Can you tell me what I am doing wring?
Thanks and kind regards
Matthias

Hi,
Sorry that this is coming a bit late, but you were probably experiencing the same issue as here:
https://github.com/vaadin/testbench/issues/887

Try using the latest TestBench version (5.1.0), the issue should be fixed there.
