----------------------------------

             Summary: Improve Jenkins set-up
                 Key: KAFKA-2566
                 URL: https://issues.apache.org/jira/browse/KAFKA-2566
             Project: Kafka
          Issue Type: Task
            Reporter: Ismael Juma


There are currently two Jenkins jobs:

https://builds.apache.org/job/Kafka-trunk
https://builds.apache.org/job/kafka-trunk-git-pr

They both run with Java 7 and execute the following gradle command:

./gradlew -PscalaVersion=2.10.1 test

There are a few issues with this:
* We don't test Java 8 even though that's the only stable release of the JDK that still receives security fixes
* We are testing with Scala 2.10.1 even though we should be testing with Scala 2.10.5
* We are not testing with Scala 2.11.x
* We are not doing clean builds

I suggest the following:

1. Change the `kafka-trunk-git-pr` job to use the `./gradlew clean test` command.
2. Change the `Kafka-trunk` job to use the `./gradlew clean testAll` command.
3. Introduce a kafka-trunk-jdk8 job with the command `./gradlew clean testAll`

This is a compromise that doesn't slow down the PR job (which is executed much more often) while still testing trunk in all of our supported JDK and Scala versions.
