not compatible with configuration as code

I think codebuild credentials are not supported.. I add the configurations downoaod from 'configurations as code" tap. But it is not working.

```

Start with the Configuration as Code path shown in the trace, especially DataBoundConfigurator and ConfigurationAsCode, and reproduce the failure using the exported configuration containing CodeBuild credentials. Done means the configuration loads without the reported NullPointerException and Jenkins completes startup.
