Having trouble with softdepend and Vault.

So I want to make it so my plugin, Fly Payment, supports an Economy paying system, (so you pay in economy currency instead of items) but when I try and make Vault a softdepend, it comes with errors when I have EconomyEnabled: true in the config, and Vault isn't present.

Here's the code for the Main Class (I commented were the error/confusion is)

I know I may be putting this in a confusing way, so if you have questions to clarify please ask, as this error has stumped some of my friends, and is very irritating! Thank you very much for even attempting to go through the code!
Thanks for reading and the feedback,
Colby

You don't need this if you require Vault for economy:
RegisteredServiceProvider<Economy> rsp = getServer().getServicesManager().getRegistration(Economy.class);
if (rsp == null) {
return false;
}
econ = rsp.getProvider();
return econ != null;
}

You also check EconEnabled before you set it.

@coldandtired
Thanks for the reply and help, but that didn't solve this issue. I still get "[SEVERE] Plugin Fly Payment is attempting to register in class net/milkbowl/vault/Vault, which does not exist. Ignoring events registered in class com.ahellhound.bukkit.flypayment.Main"

If vault is not loaded neither is the Economy class, thus Java throws a ClassNotFoundException on the line where you try to get the service provider. Either add a try...catch to catch the exception or add an if statement so that the code is only executed if vault is present (Bukkit.getPluginManager().getPlugin("Vault") != null)

What do you set the econ to then? Because rps is always null for me.

if (getServer().getPluginManager().getPlugin("Vault") != null)
{
RegisteredServiceProvider<Economy> economyProvider = getServer().getServicesManager().getRegistration(net.milkbowl.vault.economy.Economy.class);
if (economyProvider != null) economy = economyProvider.getProvider();
}

That's all you need.

EDIT: Hmmm, looking at it now, that's exactly what you already have.
