disableOssIndex not working

**Describe the bug**
Due to issues with maven and ossindex, I have tried to disable it in the additional arguments:

additionalArguments: '--exclude /.nuget/ --disableOssIndex)'

This does not work and causes the pipeline to fail with "Unrecognized option: --disableOssIndex"

**Unrecognized option: --disableOssIndex**)

**To Reproduce**
Add --disableOssIndex to your additionalArguments

**Expected behavior**
Dependency Check work
