Jenkins中groovy jsonBuilder的间歇性堆栈溢出错误

我在Jenkins中使用带有groovy后期构建插件的groovy jsonBuilder时遇到间歇性堆栈溢出错误。我要说的是，下面的代码大约有25%的时间是有效的，其余75%的时间是失败的。你知道这是什么原因吗？错误的第一部分如下。多谢各位

import groovy.json.*
import hudson.model.*


def projectName = manager.build.project.name
def job = manager.hudson.instance.getItem(projectName)
def scm = job.scm
def rtcStream = scm.getStreamName()
def rtcWorkspace = scm.getWorkspaceName()
def duration = manager.build.getExecutor().getElapsedTime()
def result = manager.build.result

def json = new JsonBuilder()

def root = json.build {
    build_number manager.build.number
    build_timestamp manager.build.timestamp
    build_duration duration
    build_url manager.build.url
    build_project_name projectName
    stream rtcStream
    workspace rtcWorkspace
    build_culprits manager.build.culprits
    build_result result.toString()
}

def jsonString = JsonOutput.prettyPrint(json.toString())
manager.listener.logger.println jsonString

def channel = manager.build.workspace.channel;

def fp = new hudson.FilePath(channel, manager.build.workspace.toString() + "\\build.json")

if(fp != null) {
    manager.listener.logger.println "Getting ready to write build.json"
    fp.write(jsonString, null); //writing to file
    manager.listener.logger.println "Done writing build.json"
}

错误：

这通常是由于一个复杂的对象本身有一个内部引用，这会导致json构建器无限循环

查看

json.build

中的所有变量，我能看到的唯一复杂变量是

manager.build.timestamp

（它是

日历

实例）

您可以尝试以下备选方案之一：

build_timestamp manager.build.timestampString // get duration of build

或

或者说

build_timestamp manager.build.timestamp.format( 'yyyy/MM/dd HH:mm:ss' )

将日历格式化为日期/时间字符串的步骤

祝你好运

听起来你的一个元素包含了它自己。。。您能记录输入并查看是哪一个导致了崩溃吗？尝试将

manager.build.timestamp

更改为

manager.build.timestamp.toString（）

当然，我无法让它失败。将toString（）添加到时间戳中会在JSON输出中给出这样的结果：“build_timestamp”：“java.util.GregorianCalendar[time=13897977000，areFieldsSet=true，areAllFieldsSet=true，lenient=true，zone=sun.util.calendar.ZoneInfo[id=\“US/Eastern\”，offset=-18000000，dstSavings=3600000，useDaylight=true，transitions=235，lastRule=java.util.SimpleTimeZone”[id=US/Eastern，offset=-18000000，dststavings=3600000，usedylight=true，startYear=0，startMode=3，startMonth=2，startDay=8，startDayOfWeek=1，startTime=7200000，startTimeMode=0，endMode=3，endMonth=10，endDay=1，……是的，我检查了这些参数，我相信这是唯一一个复杂的对象……可能

manager.build.timestampString

Is？看起来timestamp字符串实际上是以分钟为单位的构建持续时间。例如：timestamp:18分钟。我将继续这样做-我认为您是对的，这是由于timestamp对象造成的。要尝试timestamp字符串2吗

build_timestamp manager.build.timestampString2 // Not sure

build_timestamp manager.build.timestamp.format( 'yyyy/MM/dd HH:mm:ss' )
