JSON on the command line with jq in Jenkins

Question

I used jq -r '.version' package.json command to filter the version from package.json file using the terminal.

Can we use jq command in Jenkins shell without locally installing it?

Answer 1

不可以，在shell构建步骤中，您只能执行外壳可用的命令，因此您必须在系统上安装jq ，并且jenkins必须可以访问它。

Answer 2

Instead of using "jq", use the groovy.json.JsonSlurper class to parse the same output that "jq" can parse.

If "jsonStr" is a string variable with legal json content, here's an example using this:

def stuff = new JsonSlurper().parseText(jsonStr).stuff

This will get the "stuff" property in the json string and assign it to the "stuff" variable.
