There are 3 places in test with similar code

    private static Path fetch????(Class<?> clazz) {
        try {
            return ArtifactResolver.resolve(clazz).entrySet().stream()
                    .findAny().get().getValue();
        } catch (ArtifactResolverException e) {
            Throwable cause = e.getCause();
            if (cause == null) {
                throw new SkippedException("Cannot resolve artifact, "
                        + "please check if JIB jar is present in classpath.", e);
            }

            throw new SkippedException("Fetch artifact failed: " + clazz, e);
        }
    }

It can be combined into one utility method.
