Escape correctly double quotes

问题

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"

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

This is the error I get:

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