>> At the moment, for every code change in any part of the project, we need to deploy and test the whole project code
This is exactly what we do and want to do. I rather have my build/test CI tell me if I broke something than keep a mental model of where a change may have impact. It also makes our versioning and rollbacks easier since our whole codebase has a single version baked into to jar meta info. The downside is a longer build cycle. But there are some good build tools like Bazel to help reduce that time. My 2 cents.
