I think you have to use OutputStream like this in your writeKolinFilee function:

private void writeKotlinFile(String pack, String fileName, String fileContent, Element it) {
    try {
        FileObject filerSourceFile = processingEnv.getFiler().createResource(StandardLocation.SOURCE_OUTPUT,
            pack, fileName + ".kt", it);
        OutputStream outputStream = filerSourceFile.openOutputStream();
        outputStream.write(fileContent.getBytes());
        outputStream.flush();
        outputStream.close();

    } catch (Exception e) {
        e.printStackTrace();
    }
}
