Multiple regex filtering using json path.

[aytemuryakup]

Hi everyone, I'm using the generic webhook trigger plugin when triggering jenkins via gitlab. I am using the path based generic webhook trigger feature. In addition, I want to use the user_name based trigger feature. I haven't seen more than one filtering like this, is this usage possible?

• Plugin version 1.84.
• Jenkins version Jenkins 2.332.1.

My Default trigger pipeline script like this:

pipeline {
    agent any
    triggers {
        GenericTrigger(
        genericVariables: [
            [key: "changed_files", value: "\$.commits[*].['modified','added','removed'][*]"]
        ],
        genericRequestVariables: [
        [key: 'requestWithNumber', regexpFilter: ''],
        [key: 'requestWithString', regexpFilter: '$changed_files']
        ],
        causeString: 'Triggered on $changed_files',
        tokenCredentialId: 'gitlab-trigger-token',
        printContributedVariables: true,
        printPostContent: true,
        silentResponse: false,
        regexpFilterText: '$changed_files',
        regexpFilterExpression: "wheater-forecast-app/PrivateHub-Test/[^\"]+?"
        )
    }

Is it possible to use it like this? Or is the configuration correct?

What I want to do: If the committing user is DevOps, the pipeline is not triggered.

pipeline {
    agent any
    triggers {
        GenericTrigger(
        genericVariables: [
            [key: "changed_files", value: "\$.commits[*].['modified','added','removed'][*]"],
            //user_name filter
            [key: "commit_user", value: "\$.user_name"]
        ],
        genericRequestVariables: [
        [key: 'requestWithNumber', regexpFilter: ''],
        [key: 'requestWithString', regexpFilter: '$changed_files'],
        //user_name filter
        [key: 'requestWithNumber2', regexpFilter: ''],
        [key: 'requestWithString2', regexpFilter: '$commit_user'],
        ],
        causeString: 'Triggered on $changed_files',
        tokenCredentialId: 'gitlab-trigger-token',
        printContributedVariables: true,
        printPostContent: true,
        silentResponse: false,
        regexpFilterText: '$changed_files $commit_user',
        regexpFilterExpression: "wheater-forecast-app/PrivateHub-Test/[^\"]+?\\^(?!DevOps\$)"
        )
    }

What I want to do in the trigger block above: regexpFilterText: I'm calling _changesfiles and commit_user regexes.

regexpFilterExpression:

• I'm doing path-based filtering in the wheater-forecast-app/PrivateHub-Test/[^\"]+?
• I'm checking the user_name DevOps in the ^(?!DevOps\$) block.

gitlab json request output:

I thnk this regexp might work:

regexpFilterExpression: ".*"wheater-forecast-app/PrivateHub-Test/[^\"]+?\".*\\s(?!DevOps\$)"

After opening Issue, I tried combining 2 regex but triggering did not work properly. When I tried the regex you sent, it worked fine. Thanks for your support.

        GenericTrigger(
        genericVariables: [
            [key: "changed_files", value: "\$.commits[*].['modified','added','removed'][*]"],
            [key: "commit_user", value: "\$.user_name"] 
        ],
        causeString: 'Triggered on $changed_files',
        tokenCredentialId: 'gitlab-trigger-token',
        printContributedVariables: true,
        printPostContent: true,
        silentResponse: false,
        regexpFilterText: '$changed_files $commit_user',
        regexpFilterExpression: ".*\"wheater-forecast-app/PrivateHub-Test/[^\"]+?\".*\\s(?!DevOps\$)"
        )
