Kirby crashes on latest version when plugin is installed as git submodule

[nelhop]

After Updating better-rest to its latest version (1.2.8) Kirby (3.5.3.1) throws an ErrorException on startup:

Whoops\Exception\ErrorException thrown with message "include(.../site/plugins/better-rest/vendor/composer/../../tests/kirby/src/Cms/Plugin.php): failed to open stream: No such file or directory"  Stacktrace:

Should be fixed with the latest release

Unfortunately this issue is not fixed with the latest release.

It seems that /tests/kirby needs to be in the repository, but its listed in the .gitignore

[robinscholz]

could you provide a repository with a reproduction of the bug?

[nelhop]

Here you go: https://github.com/nelhop/kirby_better-rest

This is just the Kirby starterkit and better-rest as a git submodule.

@nelhop Could you try deleting the vendor folder from site/plugins/better-rest ? That should do the trick.

@robinscholz This makes Kirby available again, but crashes the API itself:

{
    "status": "error",
    "exception": "Error",
    "code": 0,
    "message": "Class 'Robinscholz\\Betterrest' not found",
    "details": null,
    "file": "plugins/better-rest/index.php",
    "line": 22
}

@nelhop Running composer dist inside site/plugins/better-rest fixes the issue for me. I'll have to talk to the kirby team to get a better understanding why this error occurs. Maybe @bnomei has an idea?
