I created a freestyle project in jenkins, in which I chose source code management as git, screenshot below
That's pretty my config. The repo you see in there is public repo. then I save the config, then I click build now.
It seems to works base on the notification on screen, which says 'success'. But I have no idea I what the heck Jenkins produced. I didn't instruct what to build and how to build. How does it know what I want? And lets say it did build something, where does it store the build? I didn't instruct it where to store the built file either. Can someone explain what is going on?
To actually build something you need to add something to your Build section in the project configuration. For a javascript configuration it might look something like:
npm install
npm run test-coverage
npm run linter
npm run complexity
where each item after run is a script in your package.json. Then you can add plugins to read the outputs of those actions, for example:
Clover test coverage publisher
TAP (Test) results publisher
HTML Publisher for publishing static analysis results
Checkstyle publisher for linting results
This allows you to pass and fail builds based on certain test criteria and where continuous integration starts to shine.
In Jenkins job you have several sections - you can define pre build actions to prepare the environment, SCM to check out from source control, Build section to run your build pipeline and post build operation to run actions after the build section.
If you defined only the SCM section all your job did is to check out your sources from the source control you provided. the status of this action is SUCCESS.
Don't forget to check the console output of the job that ran to see which steps ran.

I have created a Jenkins job and am able to assign it to run on the master/slave using their label name in Restrict where this project can be run. My job needs to do this
Copy test data to a target folder (not Jenkins workspace)
Run the test
Summarize results
Cleanup the folder with data - Yet to be implemented
Regarding step4, I have to delete the data before marking the job as complete. I have considered a Conditional Build step and it looks to be working in all cases except when the job is aborted.
I am considering a Post Build step using PostBuildTask/GroovyPostBuild and it only works when the job is assigned to run on Master. The issue here is when I try to run the job on Slave1/Slave2, the same task doesn't seem to work and I realized that its being executed on Master instead of Slave1/2.
Would appreciate any guidance on how I can solve this issue.
Thanks
Yes, Post build steps run on Master by default. So, you need another plugin allow you to choose which node you want to run Post build step. In my system, I use "Flexible Publish" plugin that I see it can solve you issue
Flexible plugin example
I have developed a webpage.In that i have a button. I want to run test cases in jenkins after clicking the button.How do i run testng testcases in Jenkins programatically ?
You will have to configure your job to trigger on that button click and write script to be executed in job config for running test cases.
OR
You can integrate your Jenkins with SCM tool.(eg GitHub)
Push your source codes files their, configure your repo with Jenkins.
You can have .xml file with target to run test cases, and u can mention that target in commands section it will run test cases OR instead of .xml file you can write entire script needed to run test cases.
(Additionally you can use github hook feature to trigger this job after new code changes have been done, so it can be tested instantly).
I hope this will give you an idea, feel free to contact if you have any queries.
I've recently found the question "How to integrate Eslint with jenkins?" and it seems great but it actually doesn't work as expected.
I've installed checkstyle with jenkins but it doesn't show up like this image:
In the post-build actions section, it does not give me the possibility to insert my eslint xml file.
Is there another way I can get checkstyle to work decently with eslint and fail build every time eslint fails?
Thank you
Unfortunately, contrary to the Build Steps the Post-Build Actions are still not sorted alphabetically in the respective dropdown list in Jenkins 1.625.1.
Publish Checkstyle analysis results is located at the very top of the list in my Jenkins after installing the Checkstyle Plugin.
See Conditional BuildStep Plugin to fail a build if a script doesn't succeed, i.e. if its return status is greater than zero.
I have a number of projects that need to be analysed by SONAR from jenkins. These projects include ant and maven projects. I have created a separate job for each SONAR analysis in jenkins.
Is it possible to have a single jenkins job in which I can pass some parameters from each individual sonar job and then see the dashboard?
If so, how do i go about it?
This solution is for Subversion and Maven.
Install the Parameterized Trigger Plugin
Create a Maven job for the SonarQube analysis, eg. _common-sonar with these settings:
Source Code Management: "Subversion", Repository URL: $PREVIOUS_SVN_URL, Check-out Strategy: "Always check out a fresh copy"
Build: Goals and options: install
Post-build Actions: "Sonar"
For the job you want to run analysis on add a Post-build Action "Trigger parameterized build on other projects" with these settings:
Projects to build: _common-sonar
Add Predefined parameters: Parameters: PREVIOUS_SVN_URL=${SVN_URL}
Now when the job-to-analyse completes it triggers the analysis job. The analysis job checks out the same SVN URL which was used by the first job.
This solution works without scripting or copying workspaces but there are quite obvious limitations and non-ideal features:
the build command is always only mvn install
the SVN checkout may be from different revision than original build
checkout and build are always done from scratch
I didn't consider ant at all here.
Improvement ideas are quite welcome!
Late improvement edit:
Instead of using a maven build ( in _common-sonar), you may also use SonarQube directly by invoking a Standalone SonarQube analysis
Additionally to the SVN URL you can add a parameter for the build tag and project name to use in sonar. Simply add
NAME=YOUR_PROJECT_NAME
BUILDTAG=$BUILD_TAG
beneath the PREVIOUS_SVN_URL parameter.
In your _common-sonar you can use it with ${NAME} and ${BUILDTAG}.
In a similar need I had once, I created a single job, which pulled sources of several projects (each to its own sub-folder in job's workspace).
Then, I wrote a simple shell script that looped over all directories and ran the sonar analysis.
The job had the sonar post build plugin which showed an aggregated report.
Unfortunately, I don't have an example as this was some years ago, but you can make it work.
I hope this helps.
I have a basic setup: some source files stored in GitHub that are pulled and built by a Jenkins job.
Now I'd like to run the unit-tests automatically when the build is done (I'm using NUnit if it can help).
I could add another build step to the "build" job to run nunit-console but I'd like to separate the build task from the unit-testing task, so that in the Jenkins dashboard I can directly see what is broken: the build or "only" the tests.
I could create another job that would pull the code-source too but it would duplicate the first job.
What's the simplest way to run the unit-tests directly on the binaries produced by the first job (run second job in the same workspace? copy the binaries? ...) ?
Thanks for any input.
You could use the Copy Artifact Plugin to copy the artefacts to another job and then run the unit tests but this may not work, depending on how C# handles packaging and the project is structured.
It look like you can use the NUint Plugin to publish the results of your tests so you may be able to use a single job as I don't think that the tests will run if the previous build step fails as they don't for JUnit tests
