The version of Zinc included with Gradle 6.4 includes a fix for the blocker
that was preventing us from passing `-release 8` to scalac.
Release notes for Gradle 6.4:
https://docs.gradle.org/6.4/release-notes.html
Reviewers: Manikumar Reddy <manikumar.reddy@gmail.com>
Scala 2.13.2 introduces support for suppressing warnings,
which makes it possible to enable fatal warnings. This is
useful enough from a development perspective to justify
this change.
In addition, Scala 2.13.2 also has a Vector implementation
with significant performance improvements and encoding
of String matches to switches.

* Introduce `gradlewAll` script to replace `*All` tasks since the approach
used by the latter doesn't work since Gradle 6.0 and it's unclear when,
if ever, it will work again ( see https://github.com/gradle/gradle/issues/11301).
* Update release script and README given the above.
* Update zinc to 1.3.5.
* Update gradle-versions-plugin to 0.28.0.
The major improvements in Gradle 6.0 to 6.3 are:
- Improved incremental compilation for Scala
- Support for Java 14 (although some Gradle plugins
like spotBugs may need to be updated or disabled,
will do that separately)
- Improved scalac reporting, warnings are clearly
marked as such, which is very helpful.
Tested `gradlewAll` manually for the commands listed in the README
and release script. For `uploadArchive`, I tested it with a local Maven
repository.

Disabled by default, but enabled for Jenkins PR builds (maximum of 1 retry per
test with up to 5 retries for the test run).
Reviewers: Ismael Juma <ismael@juma.me.uk>
* Adjust build and documentation.
* Use lambda syntax for SAM types in `core`, `streams-scala` and
`connect-runtime` modules.
* Remove `runnable` and `newThread` from `CoreUtils` as lambda
syntax for SAM types make them unnecessary.
* Remove stale comment in `FunctionsCompatConversions`,
`KGroupedStream`, `KGroupedTable' and `KStream` about Scala 2.11,
the conversions are needed for Scala 2.12 too.
* Deprecate `org.apache.kafka.streams.scala.kstream.Suppressed`
and use `org.apache.kafka.streams.kstream.Suppressed` instead.
* Use `Admin.create` instead of `AdminClient.create`. Static methods
in Java interfaces can be invoked since Scala 2.12. I noticed that
MirrorMaker 2 uses `AdminClient.create`, but I did not change them
as Connectors have restrictions on newer client APIs.
* Improve efficiency in a few `Gauge` implementations by avoiding
unnecessary intermediate collections.
* Remove pointless `Option.apply` in `ZookeeperClient`
`SessionState` metric.
* Fix unused import/variable and other compiler warnings.
* Reduce visibility of some vals/defs.

Fixed a small typo in the main README file ("They are also are printed" --> "They are also printed").
Reviewers: Manikumar Reddy <manikumar.reddy@gmail.com>
Given we need to follow the Apache rule of not checking
any binaries into the source code, Kafka has always had
a bit of a tricky Gradle bootstrap.
Using ./gradlew as users expect doesn’t work and a
local and compatible version of Gradle was required to
generate the wrapper first.
This patch changes the behavior of the wrapper task to
instead generate a gradlew script that can bootstrap the
jar itself. Additionally it adds a license, removes the bat
script, and handles retries.
The documentation in the readme was also updated.
Going forward patches that upgrade gradle should run
`gradle wrapper` before checking in the change.
With this change users using ./gradlew can be sure they
are always building with the correct version of Gradle.

Closes#7694 from arvindth/ath-debugdeps-task
- include Scala 2.13 in gradle build
- handle future milestone and RC versions of Scala in a better way
- if no Scala version is specified, default to scala 2.12 (bump from 2.11)
- include certain Xlint options (removed by Scala 2.13) for Scala 2.11/2.12 build only
- upgrade versions for dependencies:
- scalaLogging: 3.9.0 -->> 3.9.2
- scalatest: 3.0.7 -->> 3.0.8
- scoverage: 1.3.1 -->> 1.4.0

I didn't update the license header in this PR since that touches
so many files. Will file a separate one for that.

Gradle 5.0 was released on 26 November. See the release notes for enhancements and fixes: https://docs.gradle.org/5.0/release-notes.html.
A notable bugfix ensures that Javadoc artifacts are cleaned between builds.
The upgraded wrapper was spot-checked against the commands in the README and the
README was updated not to use removed system property `-Dtest.single`.
Reviewers: Ismael Juma <ismael@juma.me.uk>
Scala 2.12 has better support for newer Java versions and includes additional
compiler warnings that are helpful during development. In addition, Scala 2.11
hasn't been supported by the Scala community for a long time, the soon to be
released Spark 2.4.0 will finally support Scala 2.12 (this was the main reason
preventing many from upgrading to Scala 2.12) and Scala 2.13 is at the RC stage.
It's time to start recommending the Scala 2.12 build as we prepare support for
Scala 2.13 and start thinking about removing support for Scala 2.11.
In the meantime, Jenkins will continue to build all supported Scala versions (including
Scala 2.11) so the PR and trunk jobs will fail if people accidentally use methods
introduced in Scala 2.12.

findBugs is abandoned, it doesn't work with Java 9 and the Gradle plugin will be deprecated in
Gradle 5.0: https://github.com/gradle/gradle/pull/6664
spotBugs is actively maintained and it supports Java 8, 9 and 10. Java 11 is not supported yet,
but it's likely to happen soon.
Also fixed a file leak in Connect identified by spotbugs.
Manually tested spotBugsMain, jarAll and importing kafka in IntelliJ and running
a build in the IDE.

Closes#5625 from ijuma/kafka-5887-spotbugs
* Set --source, --target and --release to 1.8.
* Build Scala 2.12 by default.
* Remove some conditionals in the build file now that Java 8
is the minimum version.
* Bump the version of Jetty, Jersey and Checkstyle (the newer
versions require Java 8).
* Fixed issues uncovered by the new version if Checkstyle.
* A couple of minor updates to handle an incompatible source
change in the new version of Jetty.
* Add dependency to jersey-hk2 to fix failing tests caused
by Jersey upgrade.
* Update release script to use Java 8 and to take into account
that Scala 2.12 is now built by default.
* While we're at it, bump the version of Gradle, Gradle plugins,
ScalaLogging, JMH and apache directory api.
* Minor documentation updates including the readme and upgrade
notes. A number of Streams Java 7 examples can be removed
subsequently.

Closes#4200 from ijuma/scala-2.11.12-part2
0. Minor fixes on the existing examples to merge all on a single input topic; also do not use `common.utils.Exit` as it is for internal usage only.
1. Add the archetype project for the quickstart. Steps to try it out:
a. `mvn install` on the quickstart directory.
b. `mvn archetype:generate \
-DarchetypeGroupId=org.apache.kafka \
-DarchetypeArtifactId=streams-quickstart-java \
-DarchetypeVersion=1.0.0-SNAPSHOT \
-DgroupId=streams-quickstart \
-DartifactId=streams-quickstart \
-Dversion=0.1 \
-Dpackage=StreamsQuickstart \
-DinteractiveMode=false` at any directory to create the project.
c. build the streams jar with version `1.0.0-SNAPSHOT` to local maven repository with `./gradlew installAll`; `cd streams-quickstart; mvn clean package`
d. create the input / output topics, start the console producer and consumer.
e. start the program: `mvn exec:java -Dexec.mainClass=StreamsQuickstart.Pipe/LineSplit/WordCount`.
f. type data on console producer and observe data on console consumer.
