You can just run composer run-script post-install-cmd
Most likely, it will run some other scripts (in the Symfony configuration, by default they work with cache, bootstrap, etc.).
If you want to use the parameters only , create a new section in the Composers / Scripts section. Like this:
"scripts": { "post-install-cmd": [ "Incenteev\\ParameterHandler\\ScriptHandler::buildParameters", "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::buildBootstrap", "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::clearCache", "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installAssets", "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installRequirementsFile", "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::prepareDeploymentTarget" ], "post-update-cmd": [ "Incenteev\\ParameterHandler\\ScriptHandler::buildParameters", "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::buildBootstrap", "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::clearCache", "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installAssets", "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installRequirementsFile", "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::prepareDeploymentTarget" ], "build-params": [ "Incenteev\\ParameterHandler\\ScriptHandler::buildParameters" ] }, ...
and then just run composer run-script build-params
