We can choose any services for CI, but now we decided to use Jenkins, Travis CI and AppVeyor.

CI	Target OS	Target Language	Description
Jenkins CI	Windows	Java 8	Deprecated
Travis CI	Ubuntu	Oracle Java 8 OpenJDK7	Test all new pull requests Test all branch commits
AppVeyor CI	Windows	.NET VS 2013, 2015, 2017	Test all pull requests Test all commits

1. Build services provided by ASF

This page (http://ci.apache.org) contains information on the various build services that are provided to all ASF projects for continuous integration, builds, testing, snapshots and deployment. Please read this page first.

Jenkins setup

You can see more information in this link: http://wiki.apache.org/general/Jenkins?action=show&redirect=Hudson

First, you have to get an access to Jenkins (http://builds.apache.org). To get an access to Jenkins, Ask your PMC chair
If you get an access, open builds.apache.org and login with your account
Jenkins > New Item : Enter item name and check Maven project.
To trigger Github pull request builds, Follow the steps in this link: https://blogs.apache.org/infra/entry/github_pull_request_builds_now
Set JDK version to 1.7
Check "Restrict where this project can be run" and add "ubuntu" into the "Label Expression" filed. The builder will be executed on ubuntu machines. Therefore, to build in windows machine, we have to create another new item and add "windows1||windows2" into the "Label Expression".
In Build, write "clean install" into "Goals and options"
In Post Steps, check "Run regardless of build result"
If you want to update relevant JIRA issues whenever Jenkins builds the related patch, then add "Update JIRA relevant issues" in Post-build Action. To trigger this post build action, we have to insert JIRA issue number into our commit message. Here is an example commit message: "[REEF-11] Jenkins integration test".
If you have any problem using Jenkins, please file a ticket to INFRA (https://issues.apache.org/jira/browse/INFRA ) or send an email to builds@apache.org
Here is an example setting:

Rebuild

Open http://builds.apache.org and login with your account
Access a build link what you want to rebuild. (ex. https://builds.apache.org/job/Reef-pull-request-ubuntu/187/ )
Click rebuild button

Reconfiguration

Open http://builds.apache.org and login with your account
Click "Configuration" in https://builds.apache.org/job/Reef-pull-request-ubuntu/ or https://builds.apache.org/job/Reef-pull-request-windows
Change setting and click the save button

2. Travis CI

Travis-CI.org provides free service for Open Source projects.

Travis CI was enabled for apache/reef GitHub repository by Apache INFRA team : https://issues.apache.org/jira/browse/INFRA-10567

For instructions on setting up your own instance of Travis CI see Java build instructions.

3. AppVeyor

AppVeyor provides free service for Open Source projects.

For instructions on setting up your own instance of AppVeyor see C# build instructions.
