I am trying to build an angular project in Jenkins

Tried both

"build": "npm run ng build",

as well as

"build": "ng build"

but getting the same error. Could it be because of the way this project has been set up in jenkins ?

On my local machine, setting

"build": "npm run ng build"

works fine. But it fails on jenkins.

Jenkins log below -

    try `npm run build` – Kardon63 Sep 09 '20 at 18:48
  • Thanks for the quick response. Just tried it but then it run into endless loop of "npm run build" command execution. – Vivek Vermani Sep 09 '20 at 18:51

    Have you tried `npm install`? You shouldn't put 'npm run' in the same script as the script you are running. What 'npm run' does is execute that script. If the build script has 'npm run build', then typing 'npm run build' will execute that script, which will run 'npm run build' which will execute that script, which will run 'npm run build' which will execute that script. And on, and on. – Jason Goemaat Sep 09 '20 at 19:01

    What about "./node_modules/.bin/ng build". If you get Error probably working directory isn't OK – MRsa Sep 09 '20 at 19:15

    Thanks @MRsa , Yes node modules were not checked in."build" : "npm ci && npm run ng build" did the trick. Thanks everyone. Appreciate your help. – Vivek Vermani Sep 09 '20 at 21:12

in pipeline add below, i hope this will solve the problem, i was facing the same issue while using jenkins pipeline to build my react application.

pipeline{
environment { 
        CI = 'false'
    }
#your complete pipeline stages and steps for npm and other commands
