Jenkins作业可以保存在执行中，这需要对它们进行序列化。rawBuild的内容无法序列化，因此，如果要访问它，则需要在以开头的函数中进行序列化
@NonCPS。例如：
showChangeLogs()@NonCPSdef 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}" } } }}
