Problem description

I try to use vite plugin but I have everything configured to output to ./dist. I'm getting following error:

An unhandled rejection has occurred inside Forge:
Error: Electron Forge is configured to use the Vite plugin. The plugin expects the
"main" entry point in "package.json" to be ".vite/*" (where the plugin outputs
the generated files). Instead, it is "dist/electron/src/main.js"

I've check code and search for this issue. Why we cannot specify custom output dir? Why it is hardcoded

my vite.main.config.ts looks like this:

import { defineConfig } from 'vite';
import { viteStaticCopy } from 'vite-plugin-static-copy';

// https://vitejs.dev/config
export default defineConfig({
  build: {
    outDir: './dist/electron/src/',
  },
  plugins: [
    viteStaticCopy({
      targets:[
        {
          src: './projects/electron/package.json',
          dest: '../'
        }
      ]
    }),
  ],
});

Proposed solution

Allow for custom baseDir

Remove hardcoded code
