JIRA Plugin json Ressource: kann nicht in com.atlassian.json.marshal.Jsonable umgesetzt werden

Question

Problem mit der Verwendung von WebResourceDataProvider für die Bereitstellung von config, alle von Handbuch https://developer.atlassian.com/docs/advanced-topics/adding-data-providers-to-your-plugin erstellt, aber Absturz beim Versuch, eine Seite zu öffnen.

package com.company.plugins.sestit.settings; 

import com.atlassian.json.marshal.Jsonable; 
import com.atlassian.webresource.api.data.WebResourceDataProvider; 
import com.google.gson.Gson; 

import java.io.IOException; 
import java.io.Writer; 

/** 
* Provides plugin settings data as downloadable web resource. 
*/ 
public class PluginSettingsDataProvider implements WebResourceDataProvider 
{ 
    public Jsonable get() { 
     return new Jsonable() { 
      public void write(Writer writer) throws IOException { 
       String[] strings = {"abc", "def", "ghi"}; 
       writer.write(new Gson().toJson(strings)); 
      } 
     }; 
    } 
}

Answer 1

Das seltsame Fehler ist. Ich erstelle ein neues Plugin und verschiebe dort alle Funktionen, die mir helfen, das zu lösen.
