Substitute a version in json with jsonbuilder in Groovy

How to replace the version from "1.0.2" to "2.6.5" in a json file "deploy.json" using groovy scripting, and the file content has been provided below. 

{
  "versions": [
        {
            "version": "1.0.2",
            "conf": "replian"
        },
        {
            "version": "1.0.2",
            "conf": "hp"
        },
        {
            "version": "1.0.2",
            "conf": "shutoff"
        },
        {
            "version": "1.0.2",
            "conf": "spark"
        }
            ]
}

I've tried the below, but getting an error;

import groovy.json.JsonBuilder
import groovy.json.JsonSlurper

def content = """
{
  "versions": [
        {
            "version": "1.0.2",
            "conf": "replian"
        },
        {
            "version": "1.0.2",
            "conf": "hp"
        },
        {
            "version": "1.0.2",
            "conf": "shutoff"
        },
        {
            "version": "1.0.2",
            "conf": "spark"
        }
            ]
}"""

def slurped = new JsonSlurper().parseText(content)
def builder = new JsonBuilder(slurped) 
builder.content.versions.find{it.version}.version = "2.6.5"
println(builder.toPrettyString())

The issue is: Only first conf "replian" version is getting replaced when i use the above script;

{
    "version": "2.6.5",
    "conf": "replian"
},
{
    "version": "1.0.2",
    "conf": "hp"
},
{
    "version": "1.0.2",
    "conf": "shutoff"
},
{
    "version": "1.0.2",
    "conf": "spark"
}

Use collect method

import groovy.json.JsonBuilder
import groovy.json.JsonSlurper

def content = """
{
  "versions": [
        {
            "version": "1.0.2",
            "conf": "replian"
        },
        {
            "version": "1.0.2",
            "conf": "hp"
        },
        {
            "version": "1.0.2",
            "conf": "shutoff"
        },
        {
            "version": "1.0.2",
            "conf": "spark"
        }
            ]
}"""

def slurped = new JsonSlurper().parseText(content)
def builder = new JsonBuilder(slurped) 
builder.content.versions.collect{ it.version = '2.6.5' }
println(builder.toPrettyString())

Output

{
    "versions": [
        {
            "version": "2.6.5",
            "conf": "replian"
        },
        {
            "version": "2.6.5",
            "conf": "hp"
        },
        {
            "version": "2.6.5",
            "conf": "shutoff"
        },
        {
            "version": "2.6.5",
            "conf": "spark"
        }
    ]
}
