Steps to Reproduce

1. create a new maven micronaut project (micronaut 2.2.2) from https://micronaut.io/launch/ with options
   
   
   
   • java 11
   
   
   • maven
   
   
   • junit
   
   
   • openapi
   
   
2. compile app (via mvn compile or mvn mn:run)

Expected Behaviour

App is compiled without error

Actual Behaviour

maven compilation fails :

$ mvn compile

io.micronaut.openapi:micronaut-openapi:2.2.1:pom relies on

    <dependency>
      <groupId>io.micronaut</groupId>
      <artifactId>micronaut-http</artifactId>
      <scope>runtime</scope>
    </dependency>

which version is not completed from the BOM (it is in dependencyManagement, but is is not used to extend this pom)

Removing this dependency from o.micronaut.openapi:micronaut-openapi:2.2.1:pom file does allow to compile here (but would cause unexpected error in a real project where I would rather import the BOM than rely on micronaut-parent I think) .
Forcing whatever existing version for micronaut-http in this same pome (I tried with 1.0.0) fixes it also for this project (the BOM specified version is actually used at runtime).

Environment Information

• Operating System: Win10
• Micronaut Version: 2.2.2
• JDK Version: 11.0.9 (graal)
• maven Version: 3.6.3

Example Application

• use micronaut launch

[carlomorelli]

Just reproduced with Java 15 (Corretto) / mvn 3.6.3 over Win10 and MN 2.2.2.
Additional features: graphql, h2, hibernate-validator, openapi, security-jwt, views-freemarker

Also wanted to highlight that mvn mn:run fails with explicit stack trace, which roots to
Caused by: java.lang.ClassNotFoundException: io.swagger.v3.oas.annotations.responses.ApiResponse

Looks like there is a missing runtime package in the pom.xml? What should we add?

Hi,

It looks this issue came back on Micronaut 2.3.0:

[WARNING] Invalid POM for io.micronaut.openapi:micronaut-openapi:jar:2.3.0, transitive dependencies (if any) will not be available, enable debug logging for more details

Sadly, bad this is decreases the reputation of Micronaut Framework in total. Possibly you have bad DevOps engineers (or CI/CD pipelines) that can not detect those faults early.

And I do not understand Why I'm always need to specify version of Data JPA and Open API in Micronaut in pom.xml/build.gradle which is always one major version behind Micronaut version, I don't have this issue in Spring Boot.
