Unable to readfilePropertie in Jenkins Declerative Pipeline I want to read properties from ini file in workspace

Question

I am using jenkins declerative pipeline to read file properties from workspace , File is in INI format (ansible host file).

I am using following syntax but its not working throwing following error, Please suggest how to read or correct syntax to read the properties.

Groovy code:

def props  = readProperties file: 'files/hosts'
assert props['webserver']
or 
println props['webserver']
------------------------------------
hosts files contains following:
-------------------------------
[webserver]
server1
server2
[dbserver]
db1
db2

I want to read value of webserver 1 like webserver[0]...

Error which i am getting:

java.lang.NoSuchMethodError: No such DSL method 'readProperties' found among steps [ArtifactoryGradleBuild, MavenDescriptorStep, addBadge, addErrorBadge, addHtmlBadge, addInfoBadge, addInteractivePromotion, addShortText, addWarningBadge, ansiColor, ansiblePlaybook, ansibleVault, archive, artifactoryDistributeBuild, artifactoryDownload, artifactoryEditProps, artifactoryMavenBuild, artifactoryNpmInstall, artifactoryNpmPublish, artifactoryPromoteBuild, artifactoryUpload, bat, build, catchError, checkout, collectEnv, conanAddRemote, conanAddUser,  

Comments

Do you have the needed plugins installed in Jenkins? Are you using maven as the build tool?

not using maven, I need to read file properties for same condition. Which throwing above error. By the way to use file properties we need Pipeline Step Utility plugin or something else?

---

For using the def props syntax that you have used, you will need to have a pipeline utility steps plugin.
