Tip: Uploading to Google Code

I learned this the hard way: put a version number in your Google Code releases!

I kept receiving an error when I tried to upload my new Jar file.  It was the same 403 error as this person.  The problem is that you can’t overwrite files any more.  Each new download needs to have it’s own unique file name.

So, the easy fix is to include and incrementing version number in the file name.

From Ant, I was able to accomplish the version number is this manner:

  • I created a version.txt to hold a minor number and major number property — saves the version
  • In the destfile parameter of the Jar step, I use the ${major.number} and ${minor.number} properties in the file name.
  • In the release section, I use the propertyfile command to increment the version number

Here is the full Ant Build file:
