There is nothing wrong with committing generated code in Ent and Go. I don't know about Java but in Golang it does not create any platform-specific code in general, so committing code in the VCS would ensure reproducibility. It is still OK to commit without generated code and things won't break as long as you pinned the package versions correctly. But some people don't like to put extra burden in the build phase. So it is totally organization's decision whether to commit generated code or not.
