我有主从詹金斯设置。Editable Email Notification在詹金斯的一项工作中，只有当环境变量具有特定值时，我才需要通过插件发送电子邮件。所以我在Execute Shell命令中设置环境变量的值如下
echo "SHOULD_SEND_EMAIL=$should_send_email" > $WORKSPACE/build/env.properties
在构建后操作中，我有一个步骤可以使用触发器发送电子邮件，并且Script-After Build具有以下触发器脚本
def workspace = build.getWorkspace()
println "Value of workspace is ${workspace}"
filename = workspace.toString() + "/build/env.properties"
println "Value of filename is ${filename}"
def logs = readFile("${filename}")
println "Value of logs is ${logs}"
但它在错误以下失败
15:05:54 Value of workspace is /Users/jenkins/workspace/experiment-job
15:05:54 Value of filename is /Users/jenkins/workspace/experiment-job/build/env.properties
15:05:54 ERROR: Build step failed with exception

我尝试传递文件的硬编码值，考虑到 readFile 将从工作区而不是绝对路径准备好，如下所示
def logs = readFile("/build/env.properties")
println "Value of logs is ${logs}"
但它仍然失败以下错误

我不能使用https://stackoverflow.com/a/50503979/1465536中提到的文件。有人可以帮我理解这里的问题吗？如果您有任何其他解决方案可以根据情况发送电子邮件，我也很高兴知道。谢谢你。
