WingCode opened a new issue #17369:
URL: https://github.com/apache/airflow/issues/17369
**Apache Airflow version**: 2.0.0
**What happened**:
Calling `dagApi.getDag("test_dag")` fails.
The OpenApi codegen client fails with an error:
```

<!-- (please include exact error messages if you can) -->
**What you expected to happen**:
Return a DAG object
In
[https://airflow.apache.org/docs/apache-airflow/stable/_specs/v1.yaml](https://airflow.apache.org/docs/apache-airflow/stable/_specs/v1.yaml)
the tag oneOf might be causing this issue for the OpenApi & Swagger codegen.
```
oneOf:
- $ref: '#/components/schemas/TimeDelta'
- $ref: '#/components/schemas/RelativeDelta'
- $ref: '#/components/schemas/CronExpression'
```
**How to reproduce it**:
Download the openapi-cli jar from
[https://repo1.maven.org/maven2/org/openapitools/openapi-generator-cli/5.2.0/openapi-generator-cli-5.2.0.jar](https://repo1.maven.org/maven2/org/openapitools/openapi-generator-cli/5.2.0/openapi-generator-cli-5.2.0.jar)
& generate OpenApi codegen Java client by:
`java -jar openapi-generator-cli.jar generate -i ./v1.yaml -g java -o
/airflow-client-java/`
Generate Swagger codegen Java client by downloading it from:
https://editor.swagger.io/?url=https://airflow.apache.org/docs/apache-airflow/stable/_specs/v1.yaml
_NOTE: For both for the clients you might have to use the fix mentioned in
https://github.com/apache/airflow/pull/17174#issuecomment-890582941 at the time
of writing._
Write a java test code:
```
import ApiClient;
import DagAPI;
ApiClient apiClient = new ApiClient();
apiClient.setUsername("WingCode"); // Change this to your setup
apiClient.setPassword("MyNotSoSecretPassword"); // Change this to your setup
apiClient.setBasePath("http://localhost:8080/api/v1";); // Change this to
your setup
DagApi dagApi = new DagApi(apiClient);
DAGCollection a = dagApi.getDag("test_dag");
```
