Reproduce the command with swagger-codegen-cli-3.0.0-rc1 and inspect TypeScriptAngularClientCodegen alongside DefaultGenerator.java, especially the model generation path. Check why the model.mustache template is resolved as /v2/typescript-angular/v2/typescript-angular/model.mustache; done means the same Angular generation completes without the FileNotFoundException.
