Symfony4 Error loading classes custom folder "Expected to find class... but it was not found"
Update your composer.json autoload setup
{
[...]
"autoload": {
"psr-4": {
"TestNamespace\\": "TestNamespace/",
"": "src/"
}
},
[...]
}
After run: composer dump-autoload
and try again.
composer dump-autoload --classmap-authoritative
will only work if your src
directory is present at the time you run the command.
This can be an issue with multi-stage Docker builds in particular, when you are normally only copying the composer.json
/composer.lock
into the build image.
