How to use Factions as a soft depend

Hello!

I have this code:

Code:java

if (hasFactions)
            Bukkit.getPluginManager().registerEvents(new InteractListener(), this);
        else
            Bukkit.getPluginManager().registerEvents(new FactInteractListener(), this);

but whenever I use that it causes a dependency error even though the second else statement should not run. How do I handle this?

 

To add something as a depend, write one of these in your plugin.yml:

Code:

softdepend: [Factions]
depend: [Factions]

 

Yeah I do that and it still gives me the following stack trace:

Code:

Do you get any errors in your editor with your written code? If not, can you show the full code?

 

I do not get any errors in my code.

The part of the code that is relevant is the following:

if (this.getServer().getPluginManager().isPluginEnabled("Factions"))
hasFactions = true;

and the code in the first post in this thread.

That statement works just fine, as well as the else and if statement. My problem is when the plugin starts it reads the class I do not want it to read and sees there is a missing dependency, and errors out

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Try this:

Code:java

Bukkit.getServer().getPluginManager().getPlugin("Factions").isEnabled()
    hasFactions = true;

In the past, isPluginEnabled has been pretty buggy for me. This may fix your problem.

 

The boolean works fine. I have used debug code by broadcasting what it is to the server to make sure that wasn't the issue.

 

Is Factions working correctly on your server? Does factions give you errors?

 

I do not have factions on the server.... That is the whole point. I want this plugin to work when factions is not on the server AND when it is on the server.

 

EnderTroll68 You are only using "softdepend" in your plugin.yml, and not "depend"? Can you post line 36 of your main class?

 

1. if (hasFactions)
2. Bukkit.getPluginManager().registerEvents(new InteractListener(), this);
3. else
4. Bukkit.getPluginManager().registerEvents(new FactInteractListener(), this);

Line 36 is line 4 of that

 

EnderTroll68 Can you post your entire onEnable, or even better, the main class? Posting plugin.yml would be good too. Something in your code is making references to Factions regardless of its presence.

Edit: Actually, nevermind. You're registering your Factions listener when it's not present.

1. if (hasFactions)
2. Bukkit.getPluginManager().registerEvents(new InteractListener(), this);
3. else
4. Bukkit.getPluginManager().registerEvents(new FactInteractListener(), this);

 

SmooshCakez don't forget to check for null. Also funny how people claim parts of Bukkit are buggy, and solve it by doing pretty much the same thing manually as a fix.

 

If that's your definition of complaining...

 

SmooshCakez it's true though, you do the same as the 'buggy' method.
