Groovy报告文件在系统中确实存在时不存在 [英] Groovy reports that a file doesn't exists when it really is present in the system

问题描述

每当完成Jenkins作业的构建时，我都会使用Editable Email Notification插件(也称为Email-ext插件)发送包含结果的电子邮件. 另外，如果系统中存在某个文件，则我正在修改消息的默认内容，以通知该文件的存在.

Whenever a build of my Jenkins job finishes, I'm sending an email with the results using the Editable Email Notification plugin (a.k.a. Email-ext plugin). Also, if a certain file is present in the system, I'm modifying the default content of the message to notify of the existence of that file.

为此，我正在使用插件的Pre-send Script字段.

For that end, I'm using the Pre-send Script field of the plugin.

为运行准备环境

属性内容

Prepare an environment for the run

Properties Content

LOG="log.txt"

构建阶段

#!/bin/bash

touch ${WORKSPACE}/${LOG}
echo "this is just a log" >> ${WORKSPACE}/${LOG}

构建后操作

可编辑的电子邮件通知

预发送脚本

Post-build Actions

Editable Email Notification

Pre-send Script

File log = new File("${WORKSPACE}/${LOG}");
logger.println(log.text);

---

执行构建时，Jenkins将在${WORKSPACE}中创建文件并将其填充(我能够从Jenkins从站中的终端打印内容).

---

When executing the build, Jenkins will create the file in the ${WORKSPACE} and fill it (I'm able to print the contents from the terminal in the Jenkins slave).

但是当尝试从Email插件访问它时，会引发异常java.io.FileNotFoundException:

But when trying to access it from the Email plugin, the exception java.io.FileNotFoundException is raised:

我不知所措，为什么Groovy抱怨缺少文件，而如果我改为使用

I'm at a loss as why Groovy is complaining about the missing file, whereas if I instead print the path with

logger.println(log.getPath());

它将成功打印.

注意: 通知插件提供了Pre-send Script中的logger变量，以直接访问构建日志.

NOTE: The logger variable in the Pre-send Script is provided by the notification plugin to access directly the build log.

推荐答案

java.io.File方法将引用运行Jenkins的主服务器上的文件，而不是从属计算机上当前的工作空间中的文件.

java.io.File methods will refer to files on the master where Jenkins is running, so not in the current workspace on the slave machine.

要引用从属计算机上的文件，应使用readFile方法

To refer to files on the slave machine, you should use the readFile method

def log = readFile("${WORKSPACE}/${LOG}");
