Issues when installing a composer-project from scratch

[deviationist]

Hello!
I really love this, great work! :)

I have an existing composer-based WP project, where i use composer to install WP and plugins. I really would like to implement composer-plugin-language-update into this project so we can easily manage translations with composer as well.

The project is already initialized – the vendor-folder is in place and so is the WP-folder along with all the plugin-folders.

Following your guide works perfect, but – since the packages are already installed or since there are no updates available at the moment – no languages are installed. So to install languages i need to reinstall WP and each plugin.

To avoid doing this manual process, i thought it would be better to trigger a complete re-install by:

• deleting the plugins folder
• deleting the WP folder
• deleting the vendor folder
• running composer install

When I then run composer install, the "post-package-install"-script runs. Not sure whats causing this, but since the autoload.php is still not generated i get an error which is printed under.
This is how my composer.json looks like: https://pastebin.com/tHhPMF7a

Output when running composer install:

composer install

This plugin seems to make certain assumptions regarding the installation layout and file paths. For example https://github.com/Angrycreative/composer-plugin-language-update/blob/master/src/AngryCreative/PostUpdateLanguageUpdate.php#L9

require dirname( dirname( dirname( dirname( __DIR__ ) ) ) ) . '/autoload.php';

Maybe if the plugin developers would document a bit what these assumptions are so users can adapt, or replace them with some more failure resistant code that can find files from correct paths.

Hey! Sorry, I've been really slow to answer here. Yeah, this works for our setup, but obviously not everyone has the same setup. I'll set if I can have a look at a possible solution for this, otherwise PRs are most welcome!
