Description Jesse Glick 2003-10-23 16:49:48 UTC
If after running <propertyfile> you have made no actual changes to the
properties contained in it, it should avoid rewriting the file: changing the
timestamp might cause other tasks to think they are out-of-date etc. Important
in a big incremental build where the .properties file is used as an upstream
dependency.

There are three cases:

1. Property file did not exist before. Whether or not any keys are being added,
create the .properties file, and log a message (INFO).

2. Existed before, and we are making changes. Rewrite, log a message (INFO).

3. Existed before, and we are not making any changes. Just log a message (VERBOSE).

Patch includes added unit test.
