Unable to upgrade ivy.xml from 7.7.0.rc1 to 7.7.1

Resolving the cache results every time in this error:

Some projects fail to be resolved
Impossible to resolve dependencies of com.example#v7proj;working@pezi-PC
download failed: com.vaadin#vaadin-testbench-core;4.2.0-SNAPSHOT!vaadin-testbench-core.jar

I cleaned all ivy caches. Same error. No idea what is running wrong.

Solved this problem by removing the the testbench entry:

<!-- TestBench 4
        <dependency org="com.vaadin" name="vaadin-testbench-api" rev="latest.release" conf="nodeploy -> default" />
