[QUESTION] - Does this require Java to be installed on Windows 10?

Question

This is really question/clarification. I followed the steps here where it says run npm install @openapitools/openapi-generator-cli, and then you can run openapi-generator-cli.

But when I run openapi-generator-cli version, I get this error:

> openapi-generator-cli version
Download 5.0.1 ...
Downloaded 5.0.1
C:\...\node_modules\@openapitools\openapi-generator-cli\main.js:621
                error ? reject(new Error(stderr)) : resolve(stdout);
                               ^

Error: 'java' is not recognized as an internal or external command,
operable program or batch file.

    at C:\...\node_modules\@openapitools\openapi-generator-cli\main.js:621:32
    at ChildProcess.exithandler (node:child_process:316:5)
    at ChildProcess.emit (node:events:329:20)
    at maybeClose (node:internal/child_process:1055:16)
    at Process.ChildProcess._handle.onexit (node:internal/child_process:288:5)

Do I need something else? I haven't installed Java on my machine. But the instruction does not say I need it.

Steps to Reproduce

Steps to reproduce the behavior:
On Windows 10 prompt, run:

1. npm install @openapitools/openapi-generator-cli
2. openapi-generator-cli version

Then you'd get the error.

Operation System (please complete the following information):

• OS: Window
• Version 10

Yes, you will need to install JDK: https://adoptopenjdk.net/

This project is just a CLI wrapper.

If installing JDK is not an option in your use case, you may consider using Docker instead: https://hub.docker.com/r/openapitools/openapi-generator-cli
