Jenkins setup locally

[Moeby]

Hi!

So i did the setup and the configuration of jenkins, but my hosting service does not offer jenkins and other options are not free so the best solution is to have everyone set up a local jenkins themselves.

What needs to be done:

Setup Jenkins

• [x] Download the latest stable Jenkins WAR file to an appropriate directory on your machine.
• [x] Open up a terminal/command prompt window to the download directory.
• [x] Run the command java -jar jenkins.war.
• [x] Browse to http://localhost:8080 and wait until the Unlock Jenkins page appears.
• [x] jenkins will ask for a password to unlock itself. This password can be found in your cmd where you started jenkins from
• [x] Now install the suggested plugins. This will add github support to jenkins
• [x] You will be prompted to create a user for jenkins, after doing this you will be able to use the application

Add the project

• [x] Click on "New item" in the menu, give it a name and select a freestyle project

• [x] Now you need to add some options to the configuration:

  • Add that it is a github project as follows:
    • Add the source code management config (you need to add your github credentials before you can select them from the dropdown):
    • Add the triggers (the number means it will be run once a day, checking the github option means it will detect new commits and run a build after each of them)
    • Now we need to tell jenkins how to build the project. For this click "add a build step" and select "Invoke gradle script"

• In the build step you need to add another option. Click on "advanced" for the just added build script

  

• [ ] Save the configuration

Missing files

• [x] In jenkins on the project overview, click "Build now". he build will fail but the project should be downloaded from github if your configuration was done correctly.
• [x] Jenkins created a copy of the project from github locally. You might remember that we did not add the DatabaseConnection file to github for security reasons, so the local copy is also missing this file. You need to copy the whole "databaseConnection" folder and add it to your local jenkins copy so it looks like this: (Do not check it into github, this is only done locally on your PC) C:\Users_YOUR_USERNAME.jenkins\workspace\Flattie_Build\Flattie\app\src\main\java\com\tbz\mntn\flattie\databaseConnection\DatabaseConnection.java

Install lint plugin

• [x] Android studio is not using checkstyle to check for code correctness but lint. We need to add the plugin "Android Lint Plugin" which you can find here: http://localhost:8080/pluginManager/available . Check the box and then restart your jenkins (in cmd stop it and start it again).

• [x] In your project configuration in jenkins you can now add a post-build step. We do this to visualize the lint results in jenkins itself:

  

• [ ] No manually start a build again, if everything worked out you will find the android icon in your build overview which will display the results when clicked:

And that's it! now you can run the "Build now" option again in Jenkins and it should work. If it doesn't and you can't figure out why you can show me your problem in school

At the step 6 (Installation of plugins) there has been an installation failure of the "Pipeline":

Fehlermeldung beim Build nach Lint instalation:

FAILURE: Build failed with an exception.

• What went wrong: A problem occurred configuring project ':app'.

  SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable.

• Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

Solution: copy local.properties from D:\TBZ\M426 Methoden zu Softwareentwicklung Rollen Aufgaben Ergebnisse\wgapp\FlatsharePlanner\Flattie and paste it into C:\Users\Marvin.jenkins\workspace\flattie\Flattie
