# This file is only used by the Ant script.
# You can use this to override default values such as
# 'source.dir' for the location of your java source folder and
# 'out.dir' for the location of your output folder.
# You can also use it define how the release builds are signed by declaring
# the following properties:

# The password will be asked during the build when you use the 'release' target.

below to <setup import="false" />.
