Loading a composer package through a Github fork - composer-php

Question

I forked a library on Github and now want to load my fork into the project without adding the forked library into packagist. I get the following error after adding the repository and require to my composer.json:
Your requirements could not be resolved to an installable set of packages.
Problem 1
- The requested package cnizzardini/ssl-certificate could not be found in any version, there may be a typo in the package name.
Potential causes:
- A typo in the package name
- The package is not available in a stable-enough version according to your minimum-stability setting
see <https://getcomposer.org/doc/04-schema.md#minimum-stability> for more details.
Here is my full composer.json

"url": "https://github.com/cnizzardini/ssl-certificate.git"
}
],

}
I have tried adding https://github.com/cnizzardini/ssl-certificate with and without the .git. I have also tried setting minimum-stability to dev and prefer-stable to false.
Nothing works :-(

Answer 1

The composer.json file on your fork still calls the package "spatie/ssl-certificate", so that's the name of the package you need to require.
This should work:
{
...
"require": {
...
"spatie/ssl-certificate": "dev-master"
},
...
"repositories": [
{
"type": "vcs",
"url": "https://github.com/cnizzardini/ssl-certificate.git"
}
],
...
}
If it doesn't, you can rename the package on your own fork by changing the name property in its composer.json file:
{
"name": "cnizzardini/ssl-certificate",
"description": "A class to easily query the properties of an ssl certificate ",
...
}
