+ | DESCRIPTION |
+ The copy task uses org.apache.ant.tools.ant.Project.copyFile() which
+ contains a minor bug. It uses a BufferWriter or FileOutputStream and starts
+ copying the file contents, without removing the original file.
+ If the original file is a soft link (on Unix), it changes the contents of the
+ file that the soft link points to, which is not what you want IMHO.
+ One would expect the copy task to work more similar to the Unix 'cp' command
+ which creates a new file (in essence wiping out the previous file.)
+
+ To fix this, add something like this before copying the contents:
+
+ //--- Original code
+
+ ...
+ if (parent.exists())
+ {
+ parent.mkdirs();
+ }
+
+ //--- Start of insertion:
+
+ File dest = new File(destFile);
+ if (dest.exists()) dest.delete();
+
+ //---- End of insertion. Rest of original code:
+
+ if (filtering) ...
+
+ //--- etc.
+
+ I'm not sure what should happen if the existing file is a directory.
+ My guess is you would want to delete it anyway, so I don't think you need
+ to test for that.
+
+ I was using Ant 1.2 on Solaris, but the problem concerns any platform that
+ has (soft) links.
