[REQ] Add ability to skip some of the web services in an openapi contract

[nddipiazza-ebay]

Is your feature request related to a problem? Please describe.

Sometimes the openapi is huge and you only want a small number of web services to be included in the generator output.

Describe the solution you'd like

Configuration options:

• includeResources - Inclusive paths of resources to include. Anything outside of these would be skipped.

Example:

<includedResources>
  <includedResource>/hello-world</includedResource>
  <includedResource>/hello-world2</includedResource>
</includedResources>

• excludeResources - Paths of resources to exclude. Anything matching these would be skipped. Example:

<excludedResources>
  <excludedResources>/hello-world</excludedResource>
  <excludedResources>/hello-world2</excludedResource>
</excludedResources>

Describe alternatives you've considered

None of the other work arounds are as simple. Editing the openapi yaml is not attractive option. etc. The other exclusion options are not very declarative and seem to be bugged.

there's a FILTER rule in the openapi normalizer. would that meet your requirement?

          <version>6.3.0</version>

can you try the latest stable release 7.6.0 instead?

[nddipiazza-ebay]

no change. same thing. seems to ignore it.

[wing328]

can you try the CLI instead? the doc has an example

[nddipiazza-ebay]
