openapi: unused path parameter produces an error

[jonaskahn]

I created project from jooby command cli with openapi. From the beginning, it worked pretty well, after I made some change. I can't generate OPEN API , it always throw error Failed to execute goal io.jooby:jooby-maven-plugin:3.2.6:openapi (default) on project api: execution of openapi resulted in exception: Kotlin lambda not found: io/jooby/kt/Kooby.<init>(Lkotlin/jvm/functions/Function1;)V -> [Help 1]

Could you point me out which's wrong? Here is my pom setting

UPDATE 1

I guess I found the reason why. So I used anonymous object to group routes like

fun Kooby.routes() {
    mount("/api", object : Kooby({
        install(JacksonModule(JsonMapper.instance))
        mvc(HealthController::class.java)
        mvc(AuthController::class.java)
        mvc(UserController::class.java)
        mvc(TestRoleController::class.java)
    }) {})
}

class App : Kooby({
...
    routes()
...
})

I change to declare a specific class like

fun Kooby.routes() {
    mount("/api", Router())
}

private class Router : Kooby({
    install(JacksonModule(JsonMapper.instance))
    mvc(HealthController::class.java)
    mvc(AuthController::class.java)
    mvc(UserController::class.java)
    mvc(TestRoleController::class.java)
})

And now, it lead me to another error
Caused by: java.lang.NullPointerException: Cannot invoke "java.util.List.stream()" because the return value of "io.jooby.internal.openapi.OperationExt.getParameters()" is null at io.jooby.internal.openapi.OperationExt.getParameter (OperationExt.java:138) at io.jooby.openapi.OpenAPIGenerator.generate (OpenAPIGenerator.java:211)

UPDATE 2

I found the reason for the error above, I guess we have some conflictions

I tried to used static files that built in vuejs. So, To tell vuejs handle menu link I delcare some routes like belove

fun Kooby.web() {

    assets("/*", "static")

    get("/uikit*") {
        ctx.forward("/")
    }
    get("/blocks*") {
        ctx.forward("/")
    }
    get("/utilities*") {
        ctx.forward("/")
    }
    get("/documentation*") {
        ctx.forward("/")
    }
}

These line break the maven build, if I remove get line. It works.

• Another thing I test even I tried to move get method controller. If I inject context to this. It's also dead.

UPDATE 3. I come closer to the issue

• Seem regex * break the maven build openapi. If I remove * in get path. Thing work normally, but I think it should be considered as a bug ?

[jknack]

Don't think the issue is on the *. We need to isolate the offending mapping/function

[jonaskahn]

I still think it's a bug. I do create a fresh start project
This will lead program to an error when maven run

class App: Kooby({
  install(NettyServer())
  install(OpenAPIModule())
  mvc(Controller_())

  get("/api/*") {
    ctx.forward("/")
  }

})

fun main(args: Array<String>) {
  runApp(args, ::App)
}

If I change to get(/api/) , it will work.

class App: Kooby({
  install(NettyServer())
  install(OpenAPIModule())
  mvc(Controller_())

  get("/api/") {
    ctx.forward("/")
  }

})

fun main(args: Array<String>) {
  runApp(args, ::App)
}

[jknack]

with script/lambda routes the open api parser expect to find the parameter in source code, so:

  get("/some/*") {
     val value = ctx.path("*").value()
      ...
  }

Works, while this one won't:

  get("/some/*") {
      // never retrieve the *
      ctx.forward("/")
  }

That is the bug
