openapitools.json + generate error: requires option '-i' about openapi-generator-cli HOT 13 CLOSED

We have the same issue with pnpm. It happens when we invoke openapi-generator-cli (version 6.3.0) via pnpm (version 7.27.0) with the --dir flag from outside the project's root folder i.e.:

pnpm --dir <path to the projects root folder> run generate-sources

generate-sources in turn is defined as follows in the respective package.json's script section:

"generate-sources": "openapi-generator-cli generate"

The generation of types runs as part of the CI on windows, mac and linux. It only fails on windows. Furthermore it didn't cause any problems when used in conjunction with yarn and only appeared after switching to pnpm. The workaround for us is to change into the project directory and execute pnpm without --dir. It's worth noting that we have a bunch of different scripts all executed with --dir and they work flawlessly across all systems so this is likely an issue that pertains to openapi-generator-cli and not to pnpm.

I guess it's an issue with the current cwd. I'll fix it asap

from openapi-generator-cli.

which OS, Node and NPM you are using?

from openapi-generator-cli.

• npm: 6.14.8
• node: 14.12.0 / 14.13.0 (also present with the newest version)
• os: macOS 10.15.7

edit: running npm with --verbose shows that CWD points to the project root where the openapitools.json is located in.

fixed with v2.0.3

from openapi-generator-cli.

The error still appears with version 2.0.3. At least for me. Minimal example (tested on macOS, arch linux and windows):
cli_example.zip

1. run npm install to install openapi-generator-cli version 2.0.3
2. run npm run generate:openapi

Thanks, I'll check

You missed the generators node:

  "$schema": "node_modules/@openapitools/openapi-generator-cli/config.schema.json",
  "spaces": 2,
  "generator-cli": {
    "version": "5.0.0-beta2",

        "glob": ".apiSchema/swagger/*.json"
      }
    }
  }
}

I'll add a new feature to validate the given config ...

Yes, sorry I should have noticed.

I still get this error on the latest version.

Is there a workaround? I can't even figure out how to get this tool to print what Java command it is invoking so I can work around.

I'm on v 2.5.2 (latest at time of writing), Cygwin on Windows, Node 14. Here's all relevant info I can think of:

$ npx --version
6.14.17
$ npm --version
6.14.17
$ node --version
v14.20.0
$ npx openapi-generator-cli version
6.0.1
$ grep openapi-generator ../../package.json
    "@openapitools/openapi-generator-cli": "^2.5.2",
$ cat openapitools.json
{
  "$schema": "../../node_modules/@openapitools/openapi-generator-cli/config.schema.json",
  "spaces": 2,
  "generator-cli": {
    "version": "6.0.0",
    "generators": {
      "my-spec-gen": {
        "generatorName": "typescript-rxjs",
        "output": "./generated",
        "inputSpec": "./reference/my-spec.yaml"
      }
    }
  }
}
$ npx openapi-generator-cli generate
Download 6.0.1 ...

[error] Required option '-i' is missing

Any ideas what I can do to diagnose or fix?

from openapi-generator-cli.

I was able to work around by invoking Java directly:

 java -jar ../../node_modules/@openapitools/openapi-generator-cli/versions/6.0.1.jar generate -i ./reference/my-api.yaml -o generated -g typescript-rxjs

.. still not sure what's up with openapi-generator-cli or how to diagnose further. I wasn't able to get any diagnostic logs, and the main.js seems minified so I couldn't investigate further.

Found the issue!

Openapi-generator-cli is using INIT_CWD as its working directory:

When I ran my pnpm test script from a different directory (pnpm -r or pnpm run --dir) I got:

> node cwd-test.js

process.env.PWD undefined
process.env.INIT_CWD C:\Users\marek\GitHub\vsb-eink-services
process.cwd() C:\Users\marek\GitHub\vsb-eink-services\packages\facade-api-client

There's an issue in pnpm discussing where INIT_CWD is supposed to point.
