3 years ago Here is a workaround until this is fixed: Using maven-dependency-plugin, unpack the jar , copy open api yaml to a local directory, point generator to the local directory. The generator will be happy now.

Description
When migrated from swagger-codegen-maven-plugin to openapi-generator-maven-plugin we are no longer able to generate Java code from an OpenAPI specification located in a Maven JAR-dependency. The specification file is first found, then at a later stage it's no longer found.
Please note that the codegen is successful with the exact same configuration if I put the
api.ymlin the local project and point<inputSpec>to the local file, e.g.Hence:
Detailed Description
When building verbose I can see that the generator first prints my YML-file (api.yml) as JSON (OK):
Then writing model files (schemas), e.g.
Then Model Info is printed (OK):
Then Supporting file info is printed (OK):
Then writing supporting files:
So far everything looks ok and the YML-file has obviously been found by the plugin. But directly after the supporting files have been generated I get a
FileNotFoundException:The maven plugin is located at
C:\code\example-impl\functions\pom.xmlI runmvn clean installfromC:\code\example-impl\which has a parentpom.xmlto thefunctions\pom.xml(functionsis a module). One thing I noticed is that the error message above looks for the file atC:\code\example-impl\api.yml, i.e. the folder of the POM I'm running. If I runmvn clean installon the module POMC:\code\example-impl\functions\pom.xmlthen it's the same error, but it now fails with:The file is inside the JAR-dependency, not on any of the project paths.
