Solved Need help calling bStats from another class

Hi,

I know using a constructor would allow me to pull my main class into bStats, but for some reason i'm getting

Code (Java):

java.lang.IllegalArgumentException: Plugin cannot be null!

Here's my constructor in my main class

Code (Java):

    /**
     * Constructor.
     */
    public KarmaAPI() {
    }

and here's my metrics class

Code (Java):

@Module(name = "Metrics Module", desc = "A test module")
public class MetricsModule {

    private KarmaAPI karmaAPI;

    // Setup metrics
    @Inject
    public MetricsModule() {
        // Start bStats metrics
        Metrics bStats = new Metrics(karmaAPI);
    }
}

I'm using @Desetude Modularity - API to inject the class into the onEnable, which uses guice.

Here's the full error that i'm getting.

Code (Java):

1) Error injecting constructor, java.lang.IllegalArgumentException: Plugin cannot be null!

Any ideas are welcomed! It's been about 2 years since I programmed in Java, so i'm a little rusty, hopefully i'm not missing something extremely obvoius!

Thanks!

 

I'm still getting the same error, I annotated the field, and constructor. I check guice and followed there documentation and i'm still getting the error. Any more ideas?

 

I did do that, but I got a different error, saying that the plugin was initialized more than once

 

You did still help me find a fix for another project i'm working on, so I do appreciate it!

Also thank you for your help, I got it working now!
