Erroneous "unable to copy, file is symlinked outside the package" assumption in electron builder 26.0.1 #8823

lukas2 · 2025-01-30T10:06:25Z

Hi guys, we are observing a problem with version 26.0.1 if used in conjunction with quasar 4, the following happens.

 App •  WAIT  • Bundling app with electron/builder...
  • electron-builder  version=26.0.1 os=24.2.0

 App • ⚠️   FAIL  App build failed (check the log above)

Looks like some faulty assumption regarding symlinks? The images are not symlinked:

% ls -la

drwxr-xr-x  6 x10  staff    192 Aug 27 13:21 .
drwxr-xr-x  6 x10  staff    192 Aug 27 13:21 ..

Interestingly, with older quasar versions it works without a problem.

These package.json entries cause it to not work:

    "@quasar/extras": "1.16.16",
    "quasar": "2.17.7",
    "@quasar/app-webpack": "^4.0.8",
    "@quasar/quasar-app-extension-testing-unit-jest": "^3.0.3",

And these still work:

    "@quasar/extras": "1.16.15",
    "quasar": "2.17.5",
    "@quasar/app-webpack": "^3.15.1",
    "@quasar/quasar-app-extension-testing-unit-jest": "^3.0.3",

The text was updated successfully, but these errors were encountered:

Looks like "@quasar/app-webpack": "^4.0.8", is doing something weird with symlinks.
Looking at this

source=dist/electron/UnPackaged/icons/icons/appx/Square44x44Logo.png realPathFile=customer/x/app-icons/appx/Square44x44Logo.png

Where is customer/x/app-icons located? Is this a monorepo and still within project root?

Might be best to provide a minimum repro repo to help with debugging this. That way I can create a unit test around it if possible

lukas2 · 2025-01-30T16:26:36Z

Yes, it's a subfolder in the main folder where package.json, quasar config file etc. are located.

Re:

Looks like @quasar/app-webpack is doing the symlink itself.

Can you try this suggestion from quasarframework/quasar#15654

viteConf.resolve.preserveSymlinks = true

lukas2 · 2025-01-31T12:11:12Z

Thanks for the idea, but I don't think we even use vite. I might be wrong, but it's either vite or webpack, not both together.

To double check I created a vite config file, but that wasn't read.

lukas2 · 2025-01-31T13:30:00Z

I tried to use extraResources and files like this:

      extraResources: [
        {
          "from": "customer/",
          "to": "customer/",
          "filter": ["**/app-icons/appx/*.png", "**/public/mio-sdk/*.svg"]
        }
      ],

      files: [
          "**/*",
          "!customer/**/app-icons/appx/*.png",
          "!customer/**/public/mio-sdk/*.svg",
          ... other rules here ...
      ]

but to no avail.

I also deleted the culprit files, but then just other ones cause it to fail:
