Cannot use credentialsId in multibranchPipelineJob

[Polina Koornneef]

Hello,

I am trying to create multibranchPipelineJob using DSL. Here is my script:

multibranchPipelineJob('job name') {
    branchSources {
        branchSource {
            source {
                git {
                    remote('git-url')
                    credentialsId('credentialsId')
                }
            }
        }
    }
}

but I get:

Processing DSL script JenkinsItems.groovy
ERROR: (JenkinsItems.groovy, line 44) No signature of method: java.lang.String.call() is applicable for argument types: (java.lang.String) values: [656567d3-7645-4289-a0dd-fb1ef0f09536]
Possible solutions: wait(), any(), wait(long), split(java.lang.String), any(groovy.lang.Closure), each(groovy.lang.Closure)
Finished: FAILURE

Do you have any idea why credentialsId is not accepted?
