[iOS][Swift5] Can't find template files #11121

Open AdrianZghibarta opened 3 years ago

AdrianZghibarta commented 3 years ago
Description

If I'll indicate a custom folder with template files for code generation, it will throw a file not found exception, more details bellow

Swagger-codegen version

3.0.26

Command line used for generation

swagger-codegen generate -i https://docs.helloreco.holiday/swagger/support.yaml -t handlebars -l swift5 -o TestOutput/

The handlebars is a folder located in /Users/username/Documents/project-ios/RecoSwaggerClient with this structure:

-- handlebars
     -- swift5
          -- model.mustache
          -- ... other mustache files

Result after running the command in /Users/username/Documents/project-ios/RecoSwaggerClient

I had previously installed version 3.0.24 and all was working as expected, after updating to 3.0.24 I am having this error. It seems that it's trying to find the templates not directly in the indicated folder (from -t param). As well if I'll indicate another folder for -t param, let's say templates, it seems to use default templates and ignore the ones from fodler.

As well, is there any ways of downgrading to 3.0.24? I tried downloading the file from https://raw.githubusercontent.com/Homebrew/homebrew-core/e2c833d326c45d9aaf4e26af6dd8b2f31564dc04/Formula/swagger-codegen.rb and running brew install downloaded-file.rb .. but there are issues as well:

error: Failed to download resource "swagger-codegen_bottle_manifest"

try adding --template-engine mustache and in -t defining the exact relative folder, -t handlebars/swift5
