# don't change versioning scheme
# to find correct _p number, look at
# https://github.com/openjdk/jdk${SLOT}u/tags
# you will see, for example, jdk-17.0.4.1-ga and jdk-17.0.4.1+1, both point
# to exact same commit sha. we should always use the full version.
# -ga tag is just for humans to easily identify General Availability release tag.
# we need -ga tag to fetch tarball and unpack it, but exact number everywhere else to
# set build version properly
