Solved Extract a .yml from the jar in the plugin folder?

Hello ,
I want that my plugin extract a .yml which is include in the Jar into my Plugins folder but I dont know how :/
Would be nice if someone help me

 

If I recall JavaPlugin has a method for copying files out to the plugin/plugin name folder

 

Do you mean the default config.yml?

 

Thanks i will look for this but may a bit more help would be nice


EDIT:

I want to have Config and some other Files which only get copy in the plugin Folder

 

If you want to collect defaults from inside of you jar you can do this:

Code:

    customConfigFile = new File(getDataFolder(), "custom.yml");
    customConfig = YamlConfiguration.loadConfiguration(customConfigFile);
    InputStream defaultStream = getResource("custom.yml");
    YamlConfiguration defConfig = YamlConfiguration.loadConfiguration(defaultStream);
    customConfig.setDefaults(defConfig);

 

Thanks but I dosent want to collect them , only Copy

Bump :/

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

 

The wiki

 

then use the method saveResource(String location) in the javaplugin class

 

Thanks !

 

Just as general info, you can also do it manually:

Code:

File yourFile = new File(yourPluginsDirectoryPath + "yourFile.extension");
if(yourFile.exists())
return;
try {  
            FileOutputStream out = new FileOutputStream(yourFile);
           
            InputStream in = YourPluginClass.class.getResourceAsStream("yourFile.extension");
           
            int read = -1;
           
            while((read = in.read()) != -1)
                out.write(read);
           
            out.flush();
            out.close();
            in.close();
           
        } catch (Exception e) {
            e.printStackTrace();
        }

The file you want to use as ressource has to be in the same package as "YourPluginClass", otherwise use the relativ package path to the ressource. Of course when using the bukkit api it's easier to just use their method as stated by p000ison

As far as i can remember, this will break after a reload. To fix this, you need to get a URL object and turn caching off. I can post an example tomorrow

 

Never tested it thoroughly within a plugin, only within other java projects. Also the code doesn't get executed on reload cause the file usually already exists at that time. But if you want to test it and it's unsave, let me know.

 

The copy method:

Code:

public static void copy(InputStream input, File target) throws IOException
    {
        if (target.exists()) {
            throw new IOException("File already exists!");
        }
 
        File parentDir = target.getParentFile();
 
        if (!parentDir.mkdirs()) {
            throw new IOException("Failed at creating directories!");
        }
 
        if (!parentDir.isDirectory()) {
            throw new IOException("The parent of this file is no directory!?");
        }
 
        if (!target.createNewFile()) {
            throw new IOException("Failed at creating new empty file!");
        }
 
        byte[] buffer = new byte[1024];
 
        OutputStream output = new FileOutputStream(target);
 
        int realLength;
 
        while ((realLength = input.read(buffer)) > 0) {
            output.write(buffer, 0, realLength);
        }
 
        output.flush();
        output.close();
    }

To get the input stream:

Code:

public static InputStream getInputFromJar(String path) throws IOException
{
if (filename == null) {
throw new IllegalArgumentException("The path can not be null");
}
 
URL url = YOURCLASS.class.getResource(filename);
 
if (url == null) {
return null;
}
 
URLConnection connection = url.openConnection();
connection.setUseCaches(false);
return connection.getInputStream();
}
