An NVD API Key was not provided message when it has been provided.

I am having trouble getting the dependency check to run during one of our CI pipelines. No matter what I try I keep receiving the warning

```
[WARN] An NVD API Key was not provided - it is highly recommended to use an NVD API key as the update can take a VERY long time without an API Key
```

I have tried using the nvdApiKey task parameter and using the additionalArguments parameter both of which provide no solution.

Am I missing something as nobody else seems to be reporting this error.

```
