lb4 repository tool error if datasource is using injection

I have a simple data source, whos config is loaded via injection:

export class MainDataSource extends juggler.DataSource
  implements LifeCycleObserver {
  static dataSourceName = 'Main';

  constructor(
    @config()
    dsConfig: object,
  ) {
    super(dsConfig);
  }
}

Application.ts:
this.configure('datasources.Main').to(options.datasources?.Main || {});

When running the repository scaffolding tool the following error occurs:
(node:24064) UnhandledPromiseRejectionWarning: Error: Cannot load C:\lb4\src\datasources\main.datasource.config.json: ENOENT: no such file or directory, open 'C:\lb4\src\datasources\main.datasource.config.json'

I am temporarily suppressing the error by adding a main.datasource.config.json file in the source directory.

However, this scaffolding tool should not require a fully configured data source to generate simple repositories. If the configuration cannot be found, it should just emit a warning, but still allow the tool to run and generate a non-customized class using the basic boilerplate.

Start with the injected datasource setup in Application.ts and reproduce the repository scaffolding command using the missing src/datasources/main.datasource.config.json path. Trace how the tool handles the missing configuration, then verify that it warns and still generates the basic repository class without requiring the file.
