Jenkins的groovy jsonBuilder發生間歇性堆棧溢出錯誤

我使用groovy jsonBuilder與jenkins中的groovy post build插件發生間歇性堆棧溢出錯誤。我會說，下面的代碼約25％的時間工作，其他75％的時間失敗。任何想法可能導致這種情況？錯誤的第一部分在下面。謝謝。Jenkins的groovy jsonBuilder發生間歇性堆棧溢出錯誤

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()

    fp.write(jsonString, null); //writing to file 
    manager.listener.logger.println "Done writing build.json"

聽起來像你的一個元素本身...你能記錄輸入，看看哪一個是導致崩潰？ –

嘗試更改'manager.build.timestamp'到'manager.build.timestamp.toString（）' –

當然，我一直無法讓它失敗。將toString（）添加到時間戳記給了我JSON輸出中的這一點：「build_timestamp」：「java.util.GregorianCalendar [time = 1389797077000，areFieldsSet = true，areAllFieldsSet = true，lenient = true，zone = sun.util .calendar.ZoneInfo [ID = \ 「美/東\」，偏移量= -18000000，dstSavings = 3600000，useDaylight = TRUE，轉換= 235，lastRule = java.util.SimpleTimeZone中的[ID = US /東歐，偏移量= -18000000 ，startDayOfWeek = 1，startTime = 7200000，startTimeMode = 0，endMode = 3，endMonth = 10，endDay = 1，...，dstSavings = .. – JamesE

這通常是由具有內部參照本身複雜對象，這導致JSON構建器來無限引起循環。

看在json.build所有的變量，只有複雜的，我可以看到的是manager.build.timestamp（這是一個Calendar實例）

您可以嘗試以下選項之一：

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

或

build_timestamp manager.build.timestampString2 // Not sure

或事實上，

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

日曆格式化爲日期/時間字符串

手指交叉！
