Solved Get A Plugin's File

So, basically what i want to do is get a file object for the Plugin's JarFile. I do not know if this is possible, but ive done some googling and cant find anything. This must be possible, but im not sure how to go about it.

 

@meguy26 I'm not sure if this is exactly what you meant, but you could always get it by doing:

Code:

File pluginJar = new File("plugins" + File.seperator + "pluginName.jar");

 

@CodePlaysMinecraft
no, you cant, what if the jar it is renamed? what if the author has a custom name? That wont work... unfortunately.

 

@meguy26 If the jar is renamed, there isn't any way you could get the actual file object. Why would someone want to rename this, anyway?!

 

@CodePlaysMinecraft
Dunno... but maybe i was not clear enough, I need to get another plugins file, not my own... so i dont know the name. Bukkit must store them somewhere.

@CodePlaysMinecraft
Probably could have been easier, but i used the following code to populate a map of plugin name to plugin file path:

Code:

    @Override
    public void run() {
        this.populatePluginMap();
    }

    private void populatePluginMap() {
        Map<String, String> m = this.pluginFiles;
        File pd = new File("plugins");
        for (File fi : pd.listFiles()) {
            if (fi.getName().endsWith(".jar")) {
                try {
                    JarFile f = new JarFile(fi);
                    ZipEntry ent = f.getEntry("plugin.yml");
                    BufferedReader reader = new BufferedReader(new InputStreamReader(f.getInputStream(ent)));
                    String line;
                    boolean done = false;
                    while ((line = reader.readLine()) != null) {
                        if (line.startsWith("name: ")) {
                            String name = line.replaceFirst(Pattern.quote("name: "), "");
                            String loc = fi.getAbsolutePath();
                            m.put(name, loc);
                            done = true;
                            break;
                        }
                    }
                    if (!done) {
                        this.getPluginLogger().severe("The jarfile \"" + fi.getAbsolutePath()
                                + "\" could not be read into map as a plugin. Ignoring.");
                    }
                    f.close();
                } catch (IOException e) {
                    this.getPluginLogger().severe("The jarfile \"" + fi.getAbsolutePath()
                            + "\" could not be read into map as a plugin. Ignoring.");
                }
            }
        }

    }
}

Yes anyone else can use this. I will also be including this functionality in my plugin/library "MipaYrarbil"
