How to create relative symlink in Java NIO.2?

In linux we can create relative symlinks.

 ln -s targetfile symlink

In java NIO.2 

Files.createSymbolicLink(symlink, targetfile);

this code not working with relative paths.

Solution

  • Below is the code to give relative path while creating Symbolic links in order to make it accessible in cross platform environments.

    Path source = Paths.get("D:\\A\\B\\C\\D\\E\\F\\G\\a.mp4"); // original file's absolute path
Path link = Paths.get("D:\\A\\B\\C\\D\\E\\F\\H\\I\\a.mp4"); // symbolic link's absolute path
Path relativeSrc = link.getParent().relativize(source); // relative path of original file from symbolic link
    
link.getParent().toFile().mkdirs(); // create the directory hierarchy if any folder is not available 
Files.createSymbolicLink(link, relativeSrc); // create symbolic link.

    Hope this will help :)
