This commit modifies the build to require JDK 9 for
compilation. Henceforth, we will compile with a JDK 9 compiler targeting
JDK 8 as the class file format. Optionally, RUNTIME_JAVA_HOME can be set
as the runtime JDK used for running tests. To enable this change, we
separate the meaning of the compiler Java home versus the runtime Java
home. If the runtime Java home is not set (via RUNTIME_JAVA_HOME) then
we fallback to using JAVA_HOME as the runtime Java home. This enables:
- developers only have to set one Java home (JAVA_HOME)
- developers can set an optional Java home (RUNTIME_JAVA_HOME) to test
on the minimum supported runtime
- we can test compiling with JDK 9 running on JDK 8 and compiling with
JDK 9 running on JDK 9 in CI
This commit modifies the BWC build to invoke the Gradle wrapper. The
motivation for this is two-fold:
- BWC versions might be dependent on a different version of Gradle than
the current version of Gradle
- in a follow-up we are going to need to be able to set JAVA_HOME to a
different value than the current value of JAVA_HOME

When running the release tests, we set build.snapshot to false and this
causes all version numbers to not have "-SNAPSHOT". This is true even
for the tips of the branches (e.g., currently 5.6.6 on the 5.6
branch). Yet, if we do not set snapshot to false, then we would still be
trying to find artifacts with "-SNAPSHOT" appended which would not have
been build since build.snapshot is false. To fix this, we have to push
build.snapshot into the version logic.

We look for the remote by scanning the output of "git remote -v" but we
were not actually looking at the output since standard output was not
redirected anywhere. This commit fixes this issue.

The output when building bwc versions is currently verbose, with git
warnings from doing git checkout of a hash. This commit changes this to
print the useful info before and after checking out. Note that due to
using LoggedExec, if the git task exits non-zero, the entire output will
still be dumped.
This commit adds files to the build output called build_metadata which
contain key/value pairs of metadata associated with the build. The first
use of this metadata are the git hashes associated with bwc checkouts.
These metadata files will be picked up by CI intake jobs and stored
along with last-good-commit, and then passed back in throug the
BUILD_METADATA env var on periodic jobs.
The build was ignoring suffixes like "beta1" and "rc1" on the version numbers which was causing the backwards compatibility packaging tests to fail because they expected to be upgrading from 6.0.0 even though they were actually upgrading from 6.0.0-beta1. This adds the suffixes to the information that the build scrapes from Version.java. It then uses those suffixes when it resolves artifacts build from the bwc branch and for testing.

This is a regression introduced in #25510, which removed the explicit fetching of upstream. Sadly this doesn't work if you don't have any local branch referring to `upstream` as an upstream branch.
Some times we need a fix / change to have two parts in two different branches (corresponding to two different ES releases). In order to be able to test these cases you need to run the BWC tests against a local branch rather than then using a branch from `github.com/elastic/elasticsearch`.
This commit adds a system property called `tests.bwc.refspec` that allows you to do it. Note that I've chosen to go with the simplest code change for now, at the expense of some user friendliness.
Removes the `assemble` task from the `build` task when we have
removed `assemble` from the project. We removed `assemble` from
projects that aren't published so our releases will be faster. But
That broke CI because CI builds with `gradle precommit build` and,
it turns out, that `build` includes `check` and `assemble`. With
this change CI will only run `check` for projects without an
`assemble`.
Removes the `assemble` task from projects that are not published.
This should speed up `gradle assemble` by skipping projects that
don't need to be built. Which is useful because `gradle assemble`
is how we cut releases.
This commit changes the task type of the checkoutBwcBranch task to Exec
from LoggedExec so that the output of the checkout command is
shown. This enables us to see the SHA used for the checkout which can be
useful when debugging a BWC break.

Commit bf007e8d93 was a forward port of logic needed in 5.x to get
the correct bwc branch. However, other changes on master meant that this forward port was not
needed and actually broke the bwc tests. This change removes the incorrect if statement.

When testing against the previous 5.x release, the bwc project incorrectly would checkout the 5.x
branch instead of the 5.5 branch as it still had the logic that applies for major versions bwc. This change adds
a check to compare the major version when making the decision on the branch to use.
Removes the `distribution:bwc` project in favor of
`distribution:bwc-release-snapshot` and
`distribution:bwc-stable-snapshot`.
`distribution:bwc-release-snapshot` builds a snapshot of the
latest release branch (5.4 now) if needed for backwards
compatibility. `distribution:bwc-stable-snapshot` builds a
snapshot of the latest stable branch (5.x now) if needed for
backwards compatibility.
Some packaging tests depend on snapshot versions of packaging
distributions yet the build does not use a repository that includes such
distributions. While we could add such a repository, a better strategy
is to follow our approach for other BWC tests where we depend on a
locally-compiled archive distribution. This commit adds a local
compilation of packaging artifacts and substitutes these anywhere that
we would otherwise depend on a snapshot of these artifacts.
