jenkins-pipeline

I'm iterating through building a Jenkins pipeline shared library, so my Jenkinsfile is a little cleaner. I'm using the following page for guidance: https://jenkins.io/doc/book/pipeline/shared-libraries/ . I first defined several methods in individual files, like " vars/methodName.groovy ", with a " call() " method in the code. This works ok, and I particularly note that " println " calls in these methods are seen in the Jenkins console output. I then decided I wanted to save some state between method calls, so I added a new file in " vars " named " uslutils.groovy " that begins like this

I have a pipeline with multiple steps, for example: stage 'dev - compile' node('master') { //do something } stage 'test- compile' node('master') { //do something } stage 'prod- compile' node('master') { //do something } I want to send a email if something goes wrong in the job, how can I send an email no matter where the error got triggered, something like: try { /** all the code above **/ } catch(Exception e) { mail the error } I think it is a better way to use the jenkins build in post section instead of using try catch: pipeline { agent any stages { stage('whatever') { steps { ... } } }

I want to use a variable which I am using inside of my Jenkinsfile script, and then pass its value into a shell script execution (either as an environment variable or command line parameter). But the following Jenkinsfile : for (i in [ 'a', 'b', 'c' ]) { echo i sh 'echo "from shell i=$i"' } Gives the output: a from shell i= b from shell i= c from shell i= Desired output is something like: a from shell i=a b from shell i=b c from shell i=c Any idea how to pass the value of i to the shell scipt? Edit: Based upon Matt's answer, I now use this solution: for (i in [ 'a', 'b', 'c' ]) { echo i sh "i=

Using the Pipeline plugin in Jenkins 2.x , how can I access a Groovy variable that is defined somewhere at stage- or node-level from within a sh step? Simple example: node { stage('Test Stage') { some_var = 'Hello World' // this is Groovy echo some_var // printing via Groovy works sh 'echo $some_var' // printing in shell does not work } } gives the following on the Jenkins output page: [Pipeline] { [Pipeline] stage [Pipeline] { (Test Stage) [Pipeline] echo Hello World [Pipeline] sh [test] Running shell script + echo [Pipeline] } [Pipeline] // stage [Pipeline] } [Pipeline] // node [Pipeline]
