  9. good job, very simple tutorial

  10. Very useful video

  11. I have seen many tutorials.. but this one is really clear and awesome.. Explained every small step..

    Thanks a lot, Raghav!

  12. Hi

    i need some help for jenkins..

    am making new build in ITCDM and selecting environment as well. my deployment is integrated with jenkins as well. So while deploy code in itcdm , it will trigger build in jenkins and then itcdm deploy the code in respective environment.

    Problem:
    i want to take deployed environment for my other downstream jenkins job?

    Developer ->Code Deploy -> Jenkins Job (A)-> Build the code -> send back to ITCDM – but i want to take value of env from jenkins job and need to pass that value to another jenkins Job (B)

    my email: arunice17@gmail.com

  13. really awesome explanation, good going brother

  14. hi, Im not able to find the git plugin in github?Please help me?

  15. Hey Raghav! So when I give shell commands same like how you did, the build fails, I get permission denied error. And it's on Amazon ec2 server. Do I have to create a user? It's running as jenkins admin user

  16. By far the best tutorials I've seen in YouTube ,thank you.
    keep up the good work.

  17. Raghav one question what is the general practice for managing the projects in Git
    example – if I have 4 Java projects so I should create 4 repos for each or 1 repo to group them and keep the projects inside the repo, in that case how can I locate my projects from Jenkins for compilation?

  18. I would like to do more but the only thing i can tell you is thanks you 🙂

  19. Hi , Thank you for this session.
    Can we add git command like "git diff HEAD~2 HEAD" in jenkins job ?

  20. Note : In Step 5 : Configure Jenkins job to trigger the execution when a change is pushed to GitHub if you get an error
    * Failed to connect to repository Error performing command ls remote git exe -h <repo URL>

    Go to Global Tool Configuration. and check if you find an error as below.

    There's no such executable git.exe in PATH:

    So please specify the right git.exe location as per the location in your system

    ex : C:Program FilesGitbin

  21. Can we just ignore the webhook part that I've seen in other tutorials? BTW, thanks! This was helpful.

    Please Suggest.

  39. I was struggling around from a long time, I found other Channels tut very complicated….You explained it very smoothly like a butter…..Great Job …Thanks a lot.

  40. wonderfull vedio… but i am having 1 doubt here you created a project and pushed it to git..suppose if i am have downloaded the project from gitlab so just we need to give url right?? if some changes happens in that project from developer side so it will trigger automatically in jenkins ryt??

  41. one quick question : why we need step 2 ? say here i am already having my code in git , and that is triggered through the new job which i set from jenkins (after installing git plugin). then why you did step 2 ? i mean executing same program from console or using freestyle project

  42. getting this error. Failed to connect to repository : Error Performing command: Is-remote-h.

  43. Great tutorial. very recommended

  44. Good day Raghav,
    Our group is monitoring software builds that are built independently and not added to git or github. They get placed in a network file directory on our local network. Is there a way to monitor a local file in a directory so if a new file gets dropped into it we know a new software build was just added?
    Thanks

  45. Hi Raghav , is there a video by you on different ways to schedule jenkins jobs ? Here you used 5 star concept .. what other standards do we have ?
