How to generate client code using springdoc-openapi-maven-plugin and swagger-codegen-maven-plugin?

Question

My goal is to generate Spring Boot REST Client using OpenAPI 3.0.

I would like to first generate the OpenAPI specification file (springdoc-openapi-maven-plugin) of my API and then generate the client code from this file (swagger-codegen-maven-plugin) using Maven.

My problem is that swagger-codegen-maven-plugin is executed before springdoc-openapi-maven-plugin. So, the output file generated by springdoc-openapi-maven-plugin does not exist when swagger-codegen-maven-plugin executes.

How to execute springdoc-openapi-maven-plugin before swagger-codegen-maven-plugin given the following Maven build plugins configuration?

My Maven build plugin configuration:

    <build>
        <plugins>
            <plugin>

Answer 1

The issue was that springdoc-openapi-maven-plugin is executed during integration-test phase while swagger-codegen-maven-plugin default phase is generate-sources which is executed before integration-test in the build lifecycle.

I just specified a phase for swagger-codegen-maven-plugin which is after integration-test: <phase>post-integration-test</phase>.
