 This is happening because you're defining lastBuild and lastBuildResult without def, so they're scoped globally to the entire Pipeline script. And then when the Pipeline gets serialized, as happens with every step execution so that it can be resumed after a master restart, those variables are in the global scope and Pipeline attempts to serialize them. So...yeah. Be more careful about scopes. Also, we'd advise strongly against using Jenkins APIs in your Pipeline. That's not guaranteed to keep working.

 Here is the pipeline groovy code for tested. 

 

import jenkins.model.*

@NonCPS
def getJobStatus(def jobName) {
def job = Jenkins.instance.getJob(jobName)
lastBuild = job.getLastCompletedBuild()
lastBuildResult = lastBuild.getResult().toString()
return lastBuildResult;
}
node {
stage "Get Job Status"
result = getJobStatus("example_job")
print result
}
 

 Here is the failed console output:
