JENKINS
ABOUT JENKINS
• Open Source
• Easy to install
• Best known CI solution
INSTALL JENKINS
ADD PLUGINS
ADD PLUGINS
CREATE A JOB
CREATE A JOB
CREATE A JOB
• Set up Github url and restrict where the job should be run if your
mac is a node of Jenkins.
CREATE A JOB WITH PLUGINS
CREATE A JOB WITH A SCRIPT
Build your project, run Unit Tests, compute code coverage, package your app, deploy it etc…
$ pod install$ xcodebuild -workspace Lima.xcworkspace -scheme "Lima" -destination=build -configuration Debug_deploy -sdk iphoneos7.0 ONLY_ACTIVE_ARCH=YES clean build archive
$ xcodebuild -exportArchive -exportFormat "IPA" -archivePath "$NEW_ARCHIVE" -exportPath ./Lima.ipa -exportProvisioningProfile "Lima Adhoc Distribution"
# And then upload to testflight via curl
Full script here: https://gist.github.com/rvirin/7796647
PLUGINS vs SCRIPTS
Most of the time, plugins are easier to use. Sometimes we don’t have other choices to use plugins
Examples : • cocoapods plugin if podFile is not in root folder• run Unit tests with Xcode plugin
THAT’S IT, YOU CAN ENJOY NOW…
AND ONE DAY, THE BUILD FAIL !
WE NEED TO KNOW WHEN BUILD FAILED
• Basic Alert : Email
• Growl Notification : Hudson-on-cocoa
• Or you can connect Jenkins to your real life…
YOU’LL NEVER BROKE THE BUILD AGAIN !

BOTS ON iOS
SETUP - REQUIREMENTS
• A mac (at least 10.9)• OS X Server • Xcode
SETUP
• Install OS X Server and Xcode on your mac
• Activate Xcode as a service of your server
• Connect to remote repository• Create your first bot
ERRORS DURING SETUP
• Error on getting source code -> no error, big logs for nothing
• Add _teamserver public key to your Github repository (deploy keys)
ERRORS DURING SETUP
• CodeSign error: code signing is required for product type 'Application' in SDK 'iOS 7.0’ just trying to build the app !
• Get your provisionning profile on the mac server (Add your account to Xcode)
SETUP
• If you have to install your pods before building your app :
• $ sudo visudo -f /etc/sudoers
• Add this line :# Same thing without a password# %wheel ALL=(ALL) NOPASSWD: ALL%_teamsserver ALL=(ALL) NOPASSWD: ALL
• v

COOL THINGS ON BOTS
• Bots Can be created and monitored from Xcode.
• Integrate with Xcode
• UI and UX rocks.
BAD THINGS ON BOTS
• Lots of bugs
• Fetching pods before building app is painfull
• No 3rd party integration (Testflight, hockeyapp etc…)
• Can’t Archive an app
• Need to create a specific scheme
SONARAn open source platform for
Continuous Inspection of code quality
SONARQUBE
•
SONARQUBE
• Issues with OCLint are powerfull
• Generate Documentation, Count lines of code, analyze code duplication and run Unit Tests !

CONCLUSION
IMPROVEMENTS
• « Thanks to Jenkins I’m able to test the last version of our app just by pressing a button, it’s awesome ! » Alex Product Guy at Lima
IMPROVEMENTS
• « Each day at 4pm, we get a new build of our app, it’s really efficient to reduce the amount of bugs » Tester at Meetic (Dating website)
COST : 8 to 10 % of the project time
THANKS !
