@Target(value=LOCAL_VARIABLE)
 @Retention(value=SOURCE)
public @interface Cleanup

Ensures the variable declaration that you annotate will be cleaned up by calling its close method, regardless of what happens. Implemented by wrapping all statements following the local variable declaration to the end of your scope into a try block that, as a finally action, closes the resource.

Complete documentation is found at the project lombok features page for @Cleanup.

Example:

 public void copyFile(String in, String out) throws IOException {
     @Cleanup FileInputStream inStream = new FileInputStream(in);
     @Cleanup FileOutputStream outStream = new FileOutputStream(out);
     byte[] b = new byte[65536];
     while (true) {
         int r = inStream.read(b);
         if (r == -1) break;
         outStream.write(b, 0, r);
     }
 }
 

Will generate:

 public void copyFile(String in, String out) throws IOException {
     @Cleanup FileInputStream inStream = new FileInputStream(in);
     try {
         @Cleanup FileOutputStream outStream = new FileOutputStream(out);
         try {
             byte[] b = new byte[65536];
             while (true) {
                 int r = inStream.read(b);
                 if (r == -1) break;
                 outStream.write(b, 0, r);
             }
         } finally {
             if (out != null) out.close();
         }
     } finally {
         if (in != null) in.close();
     }
 }
