sed command to change value in .spec file

How to change a value in .spec file using sed. Want to change the $nmatch value of build to someother value say build1.1

{
"files": [
  {
    "aql": {
    "items.find": {
    "repo": {"$eq":"app-java-repo"},
    "path": "archives/test/app",
    "type": "folder",
    "$or": [
          {
            "$and": [
              {
                "name": {"$nmatch" : "*build*"} //change value using sed
              }
            ]
          }
        ]
      }
    }
  }
]
}

Tried below command but not working

sed -i -e '/name:/{s/\($nmatch\).*/\1: "'"build1.1"'" /}'

>Solution :

You document format is json, so you should use jq for editing:

jq '.files[0].aql."items.find"."$or"[0]."$and"[0].name."$nmatch"="build1.1"' spec

With sed, you can’t reliably access the correct name node. Your code doesn’t work because you didn’t include the quotes around name in your search pattern. Using sed would be ok if you have a unique identifier for build. Example:

sed -i 's/BUILD_NUMBER/build1.1/g' spec
