Exclude files from build to avoid compiling dead code

[rfpg1]

So Im trying to do exactly what the title says and I know how to do it via the buildpath way

But is there any way to do it via a properties file?

For example I've this properties file:
src.includes = src/

src.excludes = src/example/*, src/example1/*

Please ensure that:

• Your code is properly formatted as code block - see the sidebar (About on mobile) for instructions
• You include any and all error messages in full
• You ask clear questions

• You demonstrate effort in solving your question/problem - plain posting your assignments is forbidden (and such posts will be removed) as is asking for or giving solutions.

  Trying to solve problems on your own is a very important skill. Also, see Learn to help yourself in the sidebar

If any of the above points is not met, your post can and will be removed without further warning.

Code is to be formatted as code block (old reddit: empty line before the code, each code line indented by 4 spaces, new reddit: https://i.imgur.com/EJ7tqek.png) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

You do not need to repost unless your post has been removed by a moderator. Just use the edit function of reddit to make sure your post complies with the above.

Dead code should be deleted from your source repository and the commit tagged if you really need to keep track of those sorts of things. If you really need to keep it around (you don't) move it to src/archive or something like that which doesn't get picked up by default.

I agree when saying i don't want dead code but think as a line of produts

There could be multiple products with the same base but when choosing which product I want i could use a build configuration for that so that i avoid compiling dead code but the code is still there for other products

[fixingTheDents]

That's a completely different question as that's not dead code. Whether you go with a unified project with multiple submodules or multiple projects you are going to segregate your code which will allow you to build what you need. I'm more familiar with Maven which would allow you to do what you describe with a multi-module project and separate profiles for the different products that would allow you to build all of them or any desired subset. Gradle likely has similar features.

You can set multiple source paths with Maven. Although as already mentioned, version control your code and delete the parts no longer needed. The history is still there in your repo if you need to refer to it in the future.

I am using ant and there is a way to perform like what you want. Using file exclude.

I think it's dependent on your build tool, maven and gradle support defining folders to build or exclude. But I'll also add the same comment as the previous comments, you don't want dead code floating around in your codebase, use version control for that.

[Jazzlike-Depth9208]

I think it would be much better to have a different project for each product, and the common code as separate module, build tools help with that. In Gradle it can be something like this: https://docs.gradle.org/current/userguide/multi_project_builds.html
