Attempting to lock a resource label in a declarative pipeline script fails with the following error:
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 7: Missing required parameter: "resource" @ line 7, column 17.
lock(label: 'foo') {

The error was generated by the following declarative pipeline script:
pipeline {
agent none
stages {
stage('Build') {
agent none
steps {
lock(label: 'foo') {
echo 'Do something here that requires unique access to the resource'
}
}
}
}
}
If resource is swapped in for label, the script is able to execute. Likewise if lock call is called from a non-declarative pipeline, label works fine.
