how to implement ScriptRunner for commit/pull request, merge check for complex branches in BitBucket

[Kha Hoang]

I am having a lot of issues or not understand enough about how to implement the pre-hook in BitBucket using ScriptRunner.  I have many but following are the first 3 cases:

we are using this kind of branching scheme:

develop/proj1/feature/[A-Z]{2,9}-\d+.*
develop/proj2/feature/[A-Z]{2,9}-\d+.*
develop/proj3/feature/[A-Z]{2,9}-\d+.*

release/proj1/feature/[A-Z]{2,9}-\d+.*
release/proj2/feature/[A-Z]{2,9}-\d+.*
release/proj3/feature/[A-Z]{2,9}-\d+.*

master/proj1/feature/[A-Z]{2,9}-\d+.*
master/proj2/feature/[A-Z]{2,9}-\d+.*
master/proj3/feature/[A-Z]{2,9}-\d+.*

The pre-hook for Branch and tag naming standards enforcement seems to work fine in the statement: master/feature/(proj1|proj2|proj3)/[A-Z]{2,9}-\d+.*

Case 1:
The Require commits to be associated with a valid Jira issue doesn't work in the JQL clause template: (issuetype = feature OR issuetype = Story OR issuetype = Bug OR issuetype = Sub-Task) AND (status = 'In Progress' OR status = 'In Review'))

Case 2: 
It also doesn't work for Require that pull request associated with a valid Jira issue:
Condition: (mergeRequest.pullRequest.fromRef.displayId.matches("release/.*") || mergeRequest.pullRequest.fromRef.displayId.matches("master/.*")) &&
!(mergeRequest.pullRequest.toRef.displayId.matches("develop/.*") || mergeRequest.pullRequest.toRef.displayId.matches("feature/.*"))

JQL clause template: issuetype = (issuetype = feature OR issuetype = Story OR issuetype = Bug OR issuetype = Sub-Task) AND (status = 'In Progress' OR status = 'In Review')

Case 3: 
Merge Check, how do I implement a check so that you can't only merge from develop/proj1 to /release/proj1 and /release/proj1 to /master/proj1 but can't not merge from proj1 to be or proj2 to proj3?

How do I make it work?  Is there a good tutorial somewhere or training that I can take?  Can we implement in bash or perl script and inject it to scriptRunner instead of using groovy?

Thank you.

Cases 1. 2. Can I confirm if you already set up the Jira application link as documented in Adaptavist site?

Case 2. Following part of your condition:

mergeRequest.pullRequest.toRef.displayId.matches("feature/.*"))

probably should be: 

mergeRequest.pullRequest.toRef.displayId.matches(".*/feature/.*"))

Please note that: the condition is not for a condition to reject a pull request, instead it is a condition to check for valid Jira issue.

Case 3. You can create a "Conditional merge check" that use similar condition in your case (2). Just be mindful that: In your condition, "fromRef" refers to source branch, "toRef" refers to target branch.

I hope this helps.

Thank you so much for your response.

Case 1. 2. Yes, Jira application link was established and is working properly.

Case 2. I will try that to see if it will work; however, I think it may still not know the Jira issue information because of the complexity level of the branch.

For Case 3.  I did something like this it seems to work but I'm not sure if it's working correctly yet:

def toBranch = mergeRequest.pullRequest.toRef.displayId
def fromBranch = mergeRequest.pullRequest.fromRef.displayId

def str1 = toBranch.split('/')[1];
def str2 = fromBranch.split('/')[1];

if (str1 == str2) {
     return false;
} else {
     return true;
}
