I'm trying to add conditions to a Jenkins stage so it will only trigger when there's been a change to a .yaml file in the changeset
The code I've ended up trying is:
when { changeset '*.yaml' } According to the following site, this should cause the stage to be run when there is a change to a *.yaml file in the changeset, however this stage is always being skipped
Does anyone know where I'm going wrong, or what else I could try?
Thanks!
Jenkins must have first collected the changelog e.g. checkout scm. When you just run checkout scm in a jenkins pipeline it will tell you: ERROR: ‘checkout scm’ is only available when using “Multibranch Pipeline” or “Pipeline script from SCM”.
So add your pipeline in a Jenkinsfile to your repository. My repository contains a file test.yaml and a file Jenkinsfile with this pipeline:
pipeline{ agent any stages{ stage('checkout'){ steps{ git branch: 'master', url: 'https://github.com/xxx/xxx.git' } } stage('test'){ when { changeset "*.yaml" } steps{ echo "The file did change in the last commit (SCM checking)" } } } } Now it will work. When there was a change in Git in your file you will see:
[Pipeline] { (test) [Pipeline] echo The file did change in the last commit (SCM checking) [Pipeline] } [Pipeline] // stage And else if there was no change:
[Pipeline] { (test) Stage "test" skipped due to when conditional [Pipeline] } 
branch stage The Jenkins task is being kicked off when the 'master' branch is being updated, however, is there any chance that this mechanism causes the changeset to be passed into the Jenkinsfile somehow?
checkout and multibranch pipeline. When I add a folder to the changeset like this it doesn't work ( ) : changeset "*/folder1/**"
