Ismael Juma commented on KAFKA-2566:
------------------------------------
Guozhang, it looks good to me apart from the PR job. We should use the lowest
version of Java and Scala to ensure people don't use features from the newer
version (as per my original suggestion).

> 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 jarAll docsJarAll
> testAll` command.
> 3. Introduce a kafka-trunk-jdk8 job with the command `./gradlew clean jarAll
> docsJarAll 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.
