Pipeline - Build failed due to MissingPropertyException: No such property: env

Issue

Pipeline builds fail with the exception that looks like following:

groovy.lang.MissingPropertyException: No such property: env for class: groovy.lang.Binding

Environment

Resolution

Inspect recent changes to the Pipeline Definition looking for the following pattern:

// a.groovy
import groovy.transform.Field

@Field
def LOADED_BUILD_NUMBER = "${env.BUILD_NUMBER}"

return this
// Jenkinsfile
node() {
    checkout scm
    def a = load('a.groovy')
    echo("${env.BUILD_NUMBER}")
    echo("${a.LOADED_BUILD_NUMBER}")
}

If it is the case you are affected by the known issue [JENKINS-63384] load step fails to bind “complex” @Field defined variables. At the time of the writing (2 Oct 2020) there is no fix for it.

Workaround

Rewriting the load-ed Groovy script to avoid using of @Field initialized with values global variables. For example above script can be re-written:

// a.groovy
class BuildValueObject {
    def LOADED_BUILD_NUMBER

    BuildValueObject(script) {
        this.LOADED_BUILD_NUMBER = "${script.env.BUILD_NUMBER}"
    }
}
return new BuildValueObject(this)
