# This script file is used for travis-ci snapshot deployment.

# This script creates a maven settings file 'mySettings.xml'.
# If there is an existing settings.xml, it is used as base for the new settings file.
# After that it adds the server configuration for the sonatype maven repository
# The username and password are taken from environment variables named SONATYPE_USERNAME and SONATYPE_PASSWORD
