Git Exclude Region in Multibranch Pipeline Job Not working

[Ven H]

I have a GitHub repository and a multi-branch pipeline job. I am trying to exclude some paths from triggering builds, but can't get it to work. Any help would be appreciated. Here are the details.

GitHub URL: https://github.com/<my-org>/<project-name>.git

The project has App, DB and Config. DB and Config folders are inside the App. App is at the root level. There are 3 multibranch jobs and 3 Jenkinsfile at the following paths.

<project-name>/Jenkinsfile

<project-name>/db/Jenkinsfile

<project-name>/config/Jenkinsfile

Requirement is to ensure that a change in a file inside DB directory shouldn't trigger a build for App. PFB the checkout step in the App Jenkinsfile.

checkout([
	$class: 'GitSCM',
	branches: [[name: "*/${BRANCH_NAME}"]],
	doGenerateSubmoduleConfigurations: false,
	extensions: [[$class: 'DisableRemotePoll'],[$class: 'PathRestriction', excludedRegions: '<project-name>/db/.*', includedRegions: ''],
	[$class: 'RelativeTargetDirectory', relativeTargetDir: "<my-folder-path>"]
	],
	gitTool: "<my-git-portable>",
	submoduleCfg: [],
	userRemoteConfigs: [
	[
	credentialsId: "<my-creds>",
	url: "https://github.com/<my-org>/<project-name>.git"
	]
	]
	])

I have tried various combinations for excludedRegions like below. I tried generating the above syntax using the Pipeline Syntax with the option "Polling ignores commits in certain paths"

1. <project-name>/db/.*

2. <project-name>/db/**/*

3. db/.*

4. db/**/*

5. With and without "includedRegions"

6. With and without DisableRemotePoll (Force Polling using Workspace)

None of the above seems to be working. Can anyone please help me with this?

The git plugin provides some capabilities that are used in Freestyle projects but are not usable or are not the best choice when using a multibranch pipeline.  Path restrictions is one of those capabilities.  Rather than using the path restrictions from inside the checkout step in the Jenkinsfile, you'll need to use the Pipeline: Multibranch build strategy plugin.  

If you need to ignore changes by specific authors, you'll need to use the Ignore committer strategy plugin rather than using the git plugin facility that is similar.

Those strategies provide a higher level implementation for multibranch pipelines.  The higher level implementation can work for multiple SCM providers.

Thank you very much for your reply, Mark. Unfortunately, that is also not working for me. Can you please provide some samples? I can see from the Plugin documentation that it is excluding some files. However, I would like to exclude folders / directories. Say for example, if I have a GitHub repository like below.

https://github.com/org-name/project-name.git

The App project is at the root level and has a Jenkinsfile and an associated multibranch pipeline job in Jenkins.

I have a db directory at project-name/db path. Here also, I have a Jenkinsfile and an associated multibranch pipeline job in Jenkins.

I tried with the following path combinations in the App build multibranch pipeline configuration (cancel build excluded regions strategy) to exclude any changes in the db folder / directory from triggering an App build.

project-name/db

project-name/db/.*

project-name/db/**/*

project-name/db/**/.*

db

db/.*

db/**/*

db/**/.*

None of the above works. Please help.
