Unable to install `swagger-codegen` using brew command on Ubuntu

Platform: Ubuntu 18.04

Description

I'm using brew to install swagger-codegen. I installed brew like this:

$ sudo apt install linuxbrew-wrapper

Command line used

$ brew install swagger-codegen

This downloads, tries to install and ends with this message:

==> Downloading https://github.com/swagger-api/swagger-codegen/archive/v3.0.8.tar.gz

Error: An exception occurred within a child process:

Error:* swagger-codegen is not installed, then. *

Checks made before

I have openjdk installed:

JAVA_HOME="/usr/lib/jvm/java-1.11.0-openjdk-amd64/bin"

$ java -version
openjdk version "11.0.3" 2019-04-16
OpenJDK Runtime Environment (build 11.0.3+7-Ubuntu-1ubuntu218.04.1)
OpenJDK 64-Bit Server VM (build 11.0.3+7-Ubuntu-1ubuntu218.04.1, mixed mode, sharing)

Check version of brew:

$ brew -v
Homebrew 2.1.5
Homebrew/linuxbrew-core (git revision b1e9; last commit 2019-06-13)

Steps to reproduce

Have homebrew installed on Ubuntu. Check with brew install hello that's working properly. Than try installing swagger-codegen.

Start by reproducing brew install swagger-codegen on Ubuntu 18.04, then compare it with the working brew install hello command and inspect the reported NotImplementedError. The issue names no project files or tests; done would require identifying the installation failure's source and verifying that swagger-codegen installs successfully.
