Composer not updating autoload_namespaces.php file, despite downloading package normaly. Can't understand where i did a mistake.
If i load something from packagist, namespaces file updating successfully.
Project structure
Main Composer.json
{
"repositories":[
{
"type": "package",
"package": {
"name": "test/framework",
"version": "1.0.0.1",
"dist": {
"url": "http://localhost/repo/1.zip",
"type": "zip"
}
}
}
],
"require": {
"test/framework": "*"
}
}
Package composer.json
{
"name": "test/framework",
"type": "library",
"require": {
"php": ">=5.2.4"
},
"autoload": {
"psr-0" : {
"Test" : "lib/"
}
}
}
autoload_namespaces.php
<?php
// autoload_namespaces.php #generated by Composer
$vendorDir = dirname(dirname(__FILE__));
$baseDir = dirname($vendorDir);
return array(
);

Answer 1

You are downloading the package defined in the repositories via zip.
https://getcomposer.org/doc/05-repositories.md#package-2
In this case I feel you should define the package definition at the same place. See the above link for the example which contains autoload definition defined.
{
"repositories":[
{
"type": "package",
"package": {
"name": "test/framework",
"version": "1.0.0.1",
"dist": {
"url": "http://localhost/repo/1.zip",
"type": "zip"
},
"autoload": {
"psr-4" : {
"Test\\": "lib"
}
}
}
}
],
"require": {
"test/framework": "*"
}
}
You can also try some variation see my post over http://harikt.com/blog/2014/05/29/hidden-gems-of-composer/
PS : psr-4 is the recommended way for it can autoload psr-0 structured classes. See https://getcomposer.org/doc/04-schema.md#autoload

Answer 2

Just to add to what Hari K T said, be sure to remove the vendor directory after making an update to the composer.json file as composer uses the installed.json file in the ./vendor/composer directory to generate the autoload php files.
I had setup the composer.json correctly, but did not remove the existing vendor directory, so I assumed the answer provided by Hari K T didn't work.
