正确转义双引号 [英] Escape correctly double quotes

问题描述

我在管道中执行了以下两个命令

I have the following two commands executed inside a pipeline

def IMAGE = "url/microservices/currency-converter-search:${env.BUILD_NUMBER}"
sh "cat task-blueprint.json | jq .containerDefinitions[0].image=${IMAGE} > currency-converter-search-task-${env.BUILD_NUMBER}.json"

问题是我返回了一个错误，因为要保存的字符串需要用"双引号括起来才能用 jq

the problem is that I get back an error because the string that I need to save need to be surrounded by " double quote in order to be save by jq

这是我得到的错误:

[workspace] Running shell script
+ jq .containerDefinitions[0].image=264721266761.dkr.ecr.us-east-1.amazonaws.com/currency-converter/search:1
