openAPI generator error: Could not process model 'DateTime'. Please make sure that your schema is correct

I've decided to migrate from swagger generator to openapi generator. But during generation I have an error. Interesting that swagger works with the same yaml file and generates code without errors.

Error:

java.lang.RuntimeException: Could not process model 'DateTime'.Please make sure that your schema is correct!

The model "DateTime" defined in another yaml, that is in the same directory with generated yaml file.

UPD.

In my pom.xml file:

<plugin>
                <groupId>org.openapitools</groupId>
                <artifactId>openapi-generator-maven-plugin</artifactId>

                    </execution>
                </executions>
            </plugin>

UPD2

Reference in main yaml:

EventNotification:
  type: object
  properties:
    event:
      $ref: '#/components/schemas/SmfEvent'
    timeStamp:
      $ref: 'TS29571_CommonData.yaml#/components/schemas/DateTime'
    //and a lot of other properties

And in CommonData it looks like this:

#
# COMMON SIMPLE DATA TYPES
#
...
    DateTime:
      format: date-time
      type: string

I founded out how to pass this problem. Instead of using newest 5.1.0 version of plugin, I use 4.3.1 version and I don't have this problem. 5.x versions do not support inheritance (I had INFO log:

[deprecated] inheritance without use of 'discriminator.propertyName' has been deprecated in the 5.x release. Composed schema name: null. Title: null

But I need to use the last version. So is there another way to solve the problem?

Try changing the name of component "DateTime" to something else. I think it's naming conflict while generation or smth. At least, it's solved my problem with exact same trace.

Just in case:

<configOptions>
        <dateLibrary>java8-localdatetime</dateLibrary>
        <interfaceOnly>true</interfaceOnly>
</configOptions>

I faced a similar issue. To fix this I added dateLibrary as joda in the configOptions. Also added the dependency of joda-time.

<configOptions>
    <dateLibrary>joda</dateLibrary>
    <java8>true</java8>
    <interfaceOnly>false</interfaceOnly>
    <delegatePattern>false</delegatePattern>
    <sourceFolder>./</sourceFolder>
</configOptions>
