Add defaultreviewers to PR if particular change in a specific json file usinh hook

Hello, I'm trying to add default reviewers to a PR opened just if a field in a json is modified.

Until now i figured out just the first condition: to add defaultreviewers if a change is made in that particular file. But i will also need to somehow parse that .json diff and check if that particular field was changed. 

My code in repository events:


import com.atlassian.bitbucket.hook.HookResponse
import com.atlassian.bitbucket.repository.RefChange
import com.atlassian.bitbucket.repository.Repository


def pullRequest = event.pullRequest

if(pullRequest.pathsMatch("glob:myfile.json", pullRequest.getCommits())){
       return true
       return false


the json format:

"repositoryName": "",
"family": "none",
"developmentBranch": "master",
"emailingList": "",
"defaultReviewersForPR": "userEmail",
"nrReviewersMustApprovePR": "1",
"buildSteps": {
      "rpm": {},
      "docker": {
             "publish": true,
             "gate": true
       "helm": {
             "publish": true
       "sonar": {
             "minCoverage": "0"


I will need to add default reviewers only if the "gate" field is changed.


Is there a way to do this?

Hi @Dirlau Andrei ,

Thank you for your post.

We have published a Script to our Adaptavist Library that shows an example of blocking commits based on file content.

The Script can be found here:

Please let me know if this example helps you with what you are trying to achieve. It should be possible to edit the example to meet your needs.
