Error with changeSet in jenkins pipeline (Error:java.io.NotSerializableException: hudson.plugins.git.GitChangeSetList)

Jenkins jobs can be saved in mid execution, which requires them to be serialized. The contents of rawBuild cannot be serialized, so if you access this, you need to do so within a function that is prefaced with @NonCPS. E.g.:

showChangeLogs()

@NonCPS
def showChangeLogs() {
  def changeLogSets = currentBuild.rawBuild.changeSets
  for (int i = 0; i < changeLogSets.size(); i++) {
     def entries = changeLogSets[i].items
     for (int j = 0; j < entries.length; j++) {
          def entry = entries[j]
          echo "${entry.commitId} by ${entry.author} on ${new Date(entry.timestamp)}: ${entry.msg}"
          def files = new ArrayList(entry.affectedFiles)
          for (int k = 0; k < files.size(); k++) {
              def file = files[k]
              echo "  ${file.editType.name} ${file.path}"
          }
      }
  }
}
