custom codegen modules with Homebrew?

Description

I installed Swagger via Homebrew. Now i'm wondering how to integrate custom codegen modules with it. I was able to replace the

java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar meta \
  -o output/myLibrary -n myClientCodegen -p com.my.company.codegen

command with

swagger-codegen meta \
  -o output/myLibrary -n myClientCodegen -p com.my.company.codegen

but now i'm wondering how to use my custom module. After building it with Maven, the documentation states to

java -cp output/myLibrary/target/myClientCodegen-swagger-codegen-1.0.0.jar:modules/swagger-codegen-cli/target/swagger-codegen-cli.jar io.swagger.codegen.SwaggerCodegen

which results in

Error: Could not find or load main class io.swagger.codegen.SwaggerCodegen
Caused by: java.lang.ClassNotFoundException: io.swagger.codegen.SwaggerCodegen

I tried mvn clean install instead of mvn package, hoping the swagger-codegen command would then find the installed package for the new module, but that didn't work. Is there any way to do this, or do i have to install Swagger via Maven?

Swagger-codegen version

idk, swagger-codegen doesn't recognize the --version parameter. Installed last friday, so a very current stable release ;)

Reproduce the failure using the Homebrew swagger-codegen command and the classpath shown in the issue. Read the custom module instructions around modules/swagger-codegen-cli and output/myLibrary, then determine whether the documented invocation works with the Homebrew installation. Done means the supported integration path or limitation is documented and verified.
