When upgrading via the RPM package, we can run into a problem where
the keystore fails to be created. This arises because the %post script
on RPM runs after the new package files are installed but before the
removal of the old package files. This means that the contents of the
lib folder can contain files from the old package and the new package
and thus running the create keystore tool can encounter JAR hell
issues and fail. To solve this, we move creating the keystore to the
%posttrans script which runs after the old package files are
removed. We only need to do this on the RPM package, so we add a
switch in the shared post-install script.
This commit moves the distribution specific tasks into the respective
archives and packages builds. The collocation of common and distribution
specific tasks make it much easier to reason about what is expected in a
particular distribution.
This commit adds intermediate gradle projects for archive based
distributions (zip, tar) and package based distributions (rpm, deb). The
grouping allows the common distribution build file to be considerably
shorter and clearly separated from the common zip/tar and rpm/deb
configuration.
