Using Other Plugins from ScriptCraft

The following question gets asked a lot so I'm going to try to answer it here:

How to use other bukkit plugins API?
Like PermissionEX API.
I can check permission group by java code:
ru.tehkode.permissions.bukkit.PermissionsEx.getUser(player).inGroup("moderator");
But I can't run this code in JavaScript.
-- Bukkit forum question

The above question refers to using ScriptCraft for CraftBukkit so I'll answer that first:

You can get the permissionsEx (or any other Bukkit plugin) like this...

var pex = server.pluginManager.getPlugin('PermissionsEx');
if (pex.getUser(player).inGroup('moderator') ) {
...
}

Generally if you want to use another plugin's API, then get the plugin object by name and then call its methods. In the above example the pex variable refers to the aforementioned PermissionsEx Plugin. Once you have that reference you can call any of the plugin's methods just as you would in Java. The tricky part is getting the reference and that's where server.pluginManager.getPlugin() comes in.
