And what is your question?

 

this is don't work, how can i make it work?

 

This is my code:

Code:

static {
        try {
            FirebaseOptions options = new FirebaseOptions.Builder()//line 33
                    .setCredentials(GoogleCredentials.fromStream(new ByteArrayInputStream(key.getBytes())))
                    .setDatabaseUrl("https://yourpixel-32575.firebaseio.com")
                    .build();

            FirebaseApp.initializeApp(options);
            PlayerData.init();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

(key is static String, and i don't want to share it)


This is the error:

The jar that i export contains only my code and the plugin.yml

 

@ofeking try running 'mvn clean install' from the command line in your project directory. That's all i can think of. I have no experience with firebase.

Does it work in any other projects?

 

@Kars
this is work if i don't use plugin (just run it)
what is 'mvn clean install'?

 

Also, make sure in your pom.xml you don't have the <scope>provided</scope> in your firebase depen

 

@Machine Maker I tried, and this is didn't solve the problem.

 

Yea, okay. So you can't access the firebase API from Bukkit. You need a connector of some sort.

 

@Kars so how i do that?

 

@ofeking i dont have experience with this. But i had the same problem trying to run a spring application from a plugin. Spring needs to be run a certain way. Probably is the same way with firebase.

Either that or you just can't access the dependency somehow.

 

@Kars i think that the problem is that i access the dependency.
this is my first plugin with maven, and i don't know exactly how maven work.
i use maven because this is the single way to use firebase.
the jar don't contains only my code and the plugin.yml.
i think that the problam is that the maven don't export the firebase.

 

@ofeking Yea exactly. It is the same way with spring. But some guy wrote a connector for bukkit and spring, which made it work. You could try searching for a firebase one.

 

I succeeded, the problem was that i didn't export the firebase but now the jar is big (37MG). Can i save some space?
Sorry for my English.

 

but maybe is possible to export only what i need.
is it?

 

OK, so how i close this post?
