		if (openAPI == null) {
			throw new IllegalArgumentException("No openAPI were supplied");
		}
		String destPath = language + "-" + type.getTypeName();
		ClientOptInput clientOptInput = new ClientOptInput();
		ClientOpts clientOpts = new ClientOpts();
		String outputFolder = new File(Files.getGeneratedFilesFolder().getLocationURI().getPath(),
				new File(apiFileName, destPath).getPath()).getAbsolutePath();
		clientOptInput.opts(clientOpts).setOpenAPI(openAPI);

		CodegenConfig codegenConfig = null;
		try {
			codegenConfig = CodegenConfigLoader.forName(language);
		} catch (RuntimeException e) {
			throw new IllegalArgumentException("Could not find codegen configuration for language " + language, e);
		}
		codegenConfig.additionalProperties().put("openAPI", openAPI);//$NON-NLS-1$
		codegenConfig.setOutputDir(outputFolder);
		LOGGER.debug(Json.pretty(clientOpts));
		clientOptInput.setConfig(codegenConfig);
		new DefaultGenerator().opts(clientOptInput).generate();
