# Perform a release.
#
# Performing a release involves Maven currently to build an test things and we
# ran into problems with the default dir structure maven assumes. This script
# works around those and we need to sign the release archives anyway, which can
# be easily automated as well to not need to follow manual instructions always.
#

# log4cxx is able to build using private copies of apr and apr-util, which are
# expected in some special relative dir structure. That doesn't work with the
# default working dir "perform" uses, which is "target/checkout". So we either
# need to make apr and apr-util available in "target" or change the working
# dir. Making available seems easy using symlinks, but "mvn clean" deletes the
# contents(!) of the linked dirs then. And always copying things around seems a
# bit unnecessary as well, so I'm using a relocation of the folder for now. The
# downside is that "mvn clean" is ignoring that dir by default...
