Copy Jar File To Scripts Folder

[liverare]

You can make your jar files copy themselves across to the OSBot script directory. This is mostly useful if you plan on giving someone your script in the form of a jar file, and you can try it out yourself with my Glassblowing script.

 

 

 

Note:

• Nothing will happen if you try to run the jar file from within your script folder.
• The jar cannot delete itself. This is possible launching a batch process, but that's hacky and more effort than it's worth.

 

When you export your project to a jar, make the code below your main class:

Save as MoveToOSBotScriptFolder.java

import java.awt.Desktop;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;

import javax.swing.JOptionPane;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;

I just save all my scripts to the script folder and it overwrites them through eclipse, but nonetheless a nice snippet.

I only compile a jar file when I intend to distribute a script. Otherwise, my Eclipse will compile my script and save the compiled files to OSBot's script folder too.

How would you run a local script if you don't make a jar for it?

You don't need to. OSBot didn't always support jar files.
