Not generating anything but output success

[JFCote]

Hi,

I'm trying to use sbt-openapi-generator but unfortunately, it doesn't seems to work.

Here is the output in the command line. I receive a "success" but I can't find generated code anywhere. There is no error.

C:\dev\CS\CSBackEnd>sbt openApiGenerate
[info] welcome to sbt 1.3.13 (Oracle Corporation Java 1.8.0_201)
[info] loading global plugins from C:\Users\jcote\.sbt\1.0\plugins

[info] set current project to S360ControlSite (in build file:/C:/dev/CS/CSBackEnd/)
[success] Total time: 0 s, completed Feb 9, 2021 9:05:55 AM

I followed the example pretty closely.

Here is my config.yml

generatorName: "java-play-framework"
outputDir : "generated"
additionalProperties:
  hideGenerationTimestamp: "true"
  booleanGetterPrefix: "is"

Here is the new part of the build.sbt

lazy val generated = project.in(file("generated"))
  .settings(
    openApiInputSpec := "swagger.yaml",
    openApiConfigFile := "config.yml",
    openApiValidateSpec := SettingEnabled,
    openApiGenerateModelTests := SettingDisabled
  )

All the files are at the root, there is only one module in my project... Am I missing something important?
Thanks

Hey @JFCote! I tried out the snippets you pasted over here. I ran $ sbt openApiGenerate on Linux and then checked in the resulting generated folder. Can you do a quick check of that build definition against yours?

Can you also try running $ sbt 'show openApiGenerate' to print the list of generated files after generation, if any? The output looks something like this for me:

$ sbt 'show openApiGenerate'

@jrouly First. I must add that I'm using Windows 10 in case it might be related (even if sbt is cross platform).

Here is the result with the command sbt "show openApiGenerate". It seems to add a * in the output but I can't find any generated code.

The generated folder only contains a target folder without code.

I'm going to try with your sample project later today but here are couple of difference I can see:

• My yml spec is using OpenAPI v2 instead of v3
• My spec is very large, spawning across multiple files.

If you are on the openapi-generator slack , I could send you the files and you could test it on your side? I will try to reach you today on Slack.

@jrouly I have tried with your project in branch issue.31 and it worked. Then, I replaced your spec with mine and received this strange error. Maybe this type of log is turned off in my own project?

Let me know if you need more information.

We spoke on Slack, but summarizing here: I was able to generate code using the same sample build setup and your provided spec files, so the multi-file spec is not an issue.

When I run sbt "show openApiGenerate" using your spec files, I see the following output (snippet):

$ sbt "show openApiGenerate"

It's interesting that in your first provided output, after set current project, there's no read configuration from config.yml. This seems to indicate that the generator is not being invoked at all. I'm not entirely sure why the * is present - normally this refers to the global configuration in sbt.

Even if I run something like sbt "show compile", I still see relevant output:

@JFCote Hm. The sample build works for me on Windows 10 as well:

There's definitely something about the rest of your build context that is causing the failure. Perhaps try deleting the other sbt projects and re-adding them one at a time?
