Capacitor support detected already. Aborting.

Error message

Capacitor support detected already. Aborting.

What it means

When adding Capacitor mode (`quasar mode add capacitor`), Quasar first checks whether Capacitor support is already installed in the project. If it is, the add command is a no-op and this warning is printed instead of re-installing.

Solutions

1. Do nothing — Capacitor mode is already installed; just build: quasar dev -m capacitor or quasar build -m capacitor.
2. If you truly want a fresh setup, remove the src-capacitor directory (and capacitor devDependencies) then run quasar mode add capacitor again.
3. Suppress the warning in scripted/CI contexts by passing silent (only relevant if calling the API programmatically).

const fs = require('fs');
if (fs.existsSync('src-capacitor')) {
  console.log('Capacitor mode already installed — skip `quasar mode add capacitor`');
}

When it happens

Trigger: Running `quasar mode add capacitor` (addMode in capacitor-installation.js) when a src-capacitor directory / capacitor mode already exists in the project, unless silent===true.

Common situations: Re-running scaffolding scripts or CI provisioning twice; forgetting the mode was already added; a leftover src-capacitor folder from a previous attempt that was never removed.
