Reload plugin

How I can reload plugin, when server running?
(I would like edit and reload plugin, when server running)
(Not disable and enable!!!)
I try:

PHP:

$oldPlugin = $server->getPluginManager()->getPlugin($pluginName);
$server->getPluginManager()->disablePlugin($oldPlugin);
$pluginPath = $oldPlugin->getDataFolder();
$newPlugin = $server->getPluginManager()->loadPlugins($pluginPath);

 

what do you mean by reload if you don't mean to disable and re-enable it?

 

Simply run onEnable function to reload stuff? I'm not exactly sure what you're trying to do but modifying a working phar is a bad idea.
