RE: Is it possible to trigger a GitHub webhooks build - from another repo?

[gmaxera]

Hi,

You can do it from Jenkins itself.

 

For example, in our case we want the exact opposite, so we have in our pipeline:

 

stage('Setup') {
    when {
        beforeAgent true
        anyOf {
            triggeredBy 'UpstreamCause'
            triggeredBy 'UserIdCause'
        }
    }
    steps {

 

The above tells Jenkins to run the steps only if the build has been triggered 
by an upstream job or by a user.

 

To get what you want, you need a similar thing in repo_a, repo_b and repo_c 
that triggers the repo_main when webhook arrives:

 

stage('Setup') {
    when {
        beforeAgent true
        anyOf {
            triggeredBy 'SomethingGitHubTrigger' // look on internet for the 
exact name, I don’t know
            triggeredBy 'UserIdCause'
        }
    }
    steps {
build([
    job:
        "Your repo_main job",
    wait: false,
    propagate: false
])

 

And then everytime someone pushed on repo_a/b/c then the repo_main build is 
triggered on cascade.

 

I hope that helps.

Cheers,

Gianluca.

Subject: Is it possible to trigger a GitHub webhooks build - from another repo?

 

Hi, 

My repo_main "depends" on several other repos. It internally uses a script to 
git clone repo_a, repo_b and repo_c into subdirs. 

 

This poses a problem when using webhooks to trigger Jenkins builds from GitHub. 

 

The question is: is there a way to trigger a build in repo_main when there has 
been a push in either repo_a, repo_b, or repo_c? 

 

Any help most appreciated... 

Thanks, Danijel.
