Hi,
in my old builds jobs I often prepared some environment parameters, based
on groovy code.
For example I extracted some attribute values from an existing *.xml file:
def appServerCluster = new XmlSlurper().parse( myXmlFileAtURI )
// SSHParams is a simple Serializable Wrapper to encapsulate some values
SSHParams params = new SSHParams(appServerCluster)
return [ unixuser: params.unixuser,
dir: params.dir,
hostname: params.hostname ]
How does this approach look like now - using cps-workflow-libs ?
I couldn´t find a standard step and I also couldn´t get the shown code
running.
A simple Testpipeline looked like:
import com.mycompany.SSHParams
@NonCPS
SSHParams getSSHParams( String httpPath ) {
def appServerCluster = new XmlSlurper().parse( httpPath )
return new SSHParams(appServerCluster)
}
def params = getSSHParams(
'https://licdci01.bmwgroup.net:7993/projects/CD/repos/deployment-configs/raw/DEV/MRP/TEST/EMEA/deploy.app.xml'
)
echo params.toString()
What I got was instead was :
- a hanging job
- a job terminating with
com.cloudbees.groovy.cps.impl.CpsCallableInvocation

=> What is "best practice" to transform the old code - and to get pipeline
code running without CPS errors ?
Thanx in advance,
Torsten
