在构建时用新版本替换git子模块中的特定文件

Question

I am using an open source repo as a git submodule inside my own project.

Every time I build the whole project, I have to replace a specific file in the submodule with my own implementation. How can I do that without forking the open source repo? (The open source project is under heavy development and I get lots of conflicts when I add my own logic)

Thanks!

Answer 1

没有足够的信息可以提供具体的建议，但是我想看看是否有办法通过扩展/覆盖基础仓库中的文件而不是替换文件来找到解决方案，正如我所能做到的那样。看不到任何地方领先。

Git doesn't offer a way to let you do this natively. The version of a submodule for a particular revision is fixed, and there isn't a way to replace files in the submodule the way that you want to without maintaining your own fork.

However, you can easily do this by changing how your build operates. As part of your build process, you can copy all of the source files from one directory to another and replace or patch the files at that point, and then perform your build using the second directory as your source files.

Your question could use a little more info. There are multiple ways to solve your problem if i understand it correctly -

1. use a build script that overwrites the file in submodule and then invoke the actual toolchain to build.

2. Take a look at git post clone hooks.
