[BUG] Failure to build master branch due to a failling test

[cvgaviao]

I have cloned the openapi-generator today in order to test it with a snapshot version of swagger-parser containing a patch to an issue that bitten my spec file: swagger-api/swagger-parser#1063

So, I have changed the swagger-parser version in the master pom and tried to build.

But I'm getting a failure in this test class: org.openapitools.codegen.java.JavaModelTest on both maven or eclipse testng run:

org.openapitools.codegen.SpecValidationException: There were issues with the specification. The option can be disabled via validateSpec (Maven/Gradle) or --skip-validate-spec (CLI).
 | Error count: 1, Warning count: 0
Errors: 
	-attribute paths.'/pet/findByStatus'(get).parameters.[status].schemas.default is not of type `array`

Did some investigation in the failing method: generateModel().

Interesting to note that other tests are using petstore.yarn and no one is failing, but this test is using src/test/resources/3_0/petstore.json

Then I've converted this json into yaml and compared with the petstore.yarn in the master branch.

As I was suspecting the src/test/resources/3_0/petstore.json has a structure problem.

I successfully generated a code from my spec now, but in order to run the generator with latest swagger-parser was necessary to include explicitly this dependency in openapi-generator/modules/openapi-generator/pom.xml:

        <dependency>
            <groupId>io.swagger.parser.v3</groupId>
            <artifactId>swagger-parser</artifactId>
            <version>${swagger-parser-version}</version>
        </dependency>
