The files in ../debian/ are for stretch.
You may also use them for jessie if you have libjetty9-java from jessie-backports.

Alternates are in the subdirectories here.
To use them, copy them over the files in ../debian/  .

Built file compatibility:
trusty may be copied to vivid.
trusty may be used for jessie without libjetty9-java from backports.
xenial may be copied to yakkety, zesty
bionic may be copied to cosmic
disco may be copied to eoan

Not maintained:
wheezy files are not maintained. Use the precise files instead.
jessie files may not be maintained. Use the trusty files instead.
buster and sid files are not maintained, see the latest in Debian.

Note on systemd:

# 'dh $@ --with systemd' needs dh-systemd which isn't available in Wheezy (except from backports),
# and is only Ubuntu as of "Saucy". The official packages will enable this for Debian unstable and
# Ubuntu Saucy (and newer)

Through release 0.9.25, the debian/ directory was not current for the release;
any changes required for the build were checked in after the release.
Starting with release 0.9.26, we will attempt to test debian builds
before the release, and check in any required changes to debian/
and debian-alt/ before the release, so that the files
may actually be used to build the release.
