jenkinspipeline groovy.lang.MissingMethodException: No signature of method

Question

I have created a pipeline that takes an array of JSON objects and will call a shared library which will iterate over the JSON objects

When trying to run the Jenkins job to test that I can forward the objects but I'm seeing the following error:

hudson.remoting.ProxyException: groovy.lang.MissingMethodException: No signature of method: imageBuild.call() is applicable for argument types: (java.lang.String) values: [[{"dockerConfig":"home/pipelines/conf/journeys/dockerbuild.yaml","aquaConfig":"home/pipelines/conf/journeys/aquascan.yaml","gtag": "v1.0.1","preFixName": "journey1"},{"dockerConfig":"home/pipelines/conf/if.com/dockerbuild.yaml","aquaConfig":"home/pipelines/conf/if.com/aquascan.yaml","gtag": "v2.0.2","preFixName": "journey2"},{"dockerConfig":"home/pipelines/conf/colleague/dockerbuild.yaml","aquaConfig":"home/pipelines/conf/colleague/aquascan.yaml","gtag": "v3.0.3","preFixName": "journey2"}]]

Looks like the groovy method or global variable imageBuild in the shared library Jenkins-shared lib-cooking@BB-3611 does not expecting any parameter but you are trying to pass a string, that's the reason you are getting MissingMethodException. with the details

hudson.remoting.ProxyException: groovy.lang.MissingMethodException: No signature of method: imageBuild.call() is applicable for argument types: (java.lang.String) values

To fix the issue, you have to change the shared library method or global variable imageBuild from imageBuild() to imageBuild(String param) or imageBuild(def param)

I will try to illustrate with an example similar to your example for your reference.

Assuming you have a shared library in a git repository named - jenkins-sharedlib-cooking-lifecycle and you are following the folder structure suggested by Jenkins shared library documentation

// vars/imageBuild.groovy
import groovy.json.JsonSlurper
def call(def imagebuildParameter) {
  def jsonSlurper = new JsonSlurper()
  def object = jsonSlurper.parseText(imagebuildParameter)
  // use loop on object to retrive the value like below  
  println object[0].name
}

//Jenkinsfile
node {
  stage('stageName') {
    def x = '[{"name": "foo"},{"name": "bar"}]'
    imageBuild(x)
  }
}
