Yeah, it is intresting, by default when you run serve, we run dev server on both compiation (but we keep files in memory), to solve it we need:

1. Allow to disable dev server for required compilation, here is issue serve does not work with multi-server webpack-cli#2408

As workaround now you can do it:

const path = require("path");

module.exports = [
    {
        mode: "production",
        name: "build1",
        entry: "./src1",
        output: { filename: "build1.js", path: path.resolve(__dirname, "src2") },
        devServer: {
            devMiddleware: {
                writeToDisk: true,
            }
        }
    },
    {
        mode: "production",
        name: "app",
        dependencies: ["build1"],
        entry: "./src2",
    }
];

I want to close the issue here (in favor webpack/webpack-cli#2408), because we should fix bug/implement enchantment in webpack-cli.

Feel free to feedback
