my-vendor.sh

#!/bin/bash
                    
MY_VENDOR_DIRECTORY=my-vendor
VENDOR_DIRECTORY=vendor

if [ ! -d "$MY_VENDOR_DIRECTORY" ]
then
  echo "Le dossier $MY_VENDOR_DIRECTORY n'existe pas : on le crée."
  mkdir $MY_VENDOR_DIRECTORY
else
  echo "Le dossier $MY_VENDOR_DIRECTORY existe : on le vide."
  rm -rf $MY_VENDOR_DIRECTORY/*
fi

echo "Copie des fichiers autoload généré depuis $VENDOR_DIRECTORY vers $MY_VENDOR_DIRECTORY."
cp $VENDOR_DIRECTORY/autoload.php $MY_VENDOR_DIRECTORY
cp -R $VENDOR_DIRECTORY/composer $MY_VENDOR_DIRECTORY

cd $MY_VENDOR_DIRECTORY/composer
echo "Remplacement de 'require \$file' par \str_replace(\"my-vendor\/composer\/..\", \"vendor\", \$file)"
sed -i 's/require $file/require \\str_replace("my-vendor\/composer\/..", "vendor", $file)/' autoload_real.php
echo "Remplacement de 'include \$file' par \str_replace(\"my-vendor\/composer\/..\", \"vendor\", \$file) "
sed -i 's/include $file/require \\str_replace("my-vendor\/composer\/..", "vendor", $file)/' ClassLoader.php

This script can be usefull when you want two Laravel projects to share the same vendor folder.

1. Put this script at the root of your differents projects (dont forget to chmod +x)
2. In public/index.php, replace require __DIR__.'/../vendor/autoload.php'; by require __DIR__.'/../my-vendor/autoload.php';
3. Add ./my-vendor.sh in your composer.json in the post-autoload-dump
4. (Optionnal) Add my-vendor directory in your .gitignore

I only try this shellscript in the context of two laravel projects which shares the same vendor folder.
