Steps to reproduce

• create new project with defaults
• change the serve command to the following: vue-cli-service build --watch --dest public/build
• run yarn serve

What is expected?

rebuild when file changes

What is actually happening?

it rebuilds in an infinite loop and creates infinite build folders inside public/build

Would you be interested in a PR that adds this as a configuration option?

Sorry but no. We aim to provide consistent project layouts with Vue ClI, so static assets should always go into /public. Users are free to change it on their own if they must.

Managed to solve it with the following, big thanks to @LinusBorg for the advice:

// vue.config.js
module.exports = {
    chainWebpack: config => {
        if (config.plugins.has('copy')) {
            config.plugins.delete('copy')
        }
    }
}

This assumes (as in my specific case) that you don’t need the statics in the public folder
